Volatiles are an essential aspect of subduction zones and constraining their cycling through subduction zones is of prime importance to better understand the genesis, transport, storage and eruption of arc magmas. Here we performed an along-arc investigation of the chemical composition of melt inclusions trapped in minerals representative of ten volcanic centers and 23 key explosive eruptions along the presently active Lesser Antilles arc, from Montserrat in the North to St. Vincent in the South. We use the melt inclusion compositions to reconstruct pre-eruptive conditions, especially pre-eruptive magma storage and degassing levels that highlight how the magma plumbing system is organized and works and to discuss magma source characteristics. All major and selected trace elements and volatiles (H₂O, CO₂, S, halogens (F, Cl, Br)) have been measured on the same melt inclusions when possible. Eruptions dominantly involved andesitic to dacitic magmas (Montserrat, Guadeloupe, Dominica, Martinique, St. Lucia) and basaltic andesite magmas from St. Vincent.

Melt inclusions have been used as pressure probes for magmas, for inferring crustal equilibration pressures. We shed light on the systematic occurrence and lateral complexity of a vertical transcrustal magmatic systems feeding active volcanoes. The geochemical view of the architecture of the plumbing system and in particular the Moho's depth is more variable than the view obtained by seismic data along the Lesser Antilles arc. We propose that the discontinuity between the upper and the middle crust is a major magma ponding zone beneath most of the Lesser Antilles islands and that the crustal structure thus imparts a control on the geochemical signature of arc lavas.

Melt inclusions are highly differentiated (dacitic to rhyolitic in composition), so they are distant in composition from the primary, mantle-derived magmas, but they provide indirect information about the magmatic sources. The along-arc variability in Y and heavy rare earth element contents of melt inclusions is consistent with the presence of garnet in the mantle source. Our results also indicate an important contribution of oxidized and saline slab-derived fluids to the magma source predominantly in the southern Lesser Antilles that may have implication on the accretionary system behaviour. In addition, a high geographical gradient between sediment melt and slab-derived fluid contributions,
48 illustrating high variability in magmas erupted in close spatial association is reported for some islands,
49 such Martinique and Dominica. Volatile contents are variable for MIs across the arc: the highest
50 H₂O (<8 wt%), Cl (up to 3800 ppm) and Br (up to 20 ppm) concentrations occur in MIs from
51 Dominica. But there is no systematic correlation between MI volatile content and position along the
52 arc. Halogen Cl/F and Cl/Br ratios vary from one island to another, even between the different
53 eruptions, but without any along arc zoning, indicating that halogen fractionation occurred by fluid
54 transfer (variable assimilation rate of fluids derived from seawater) or by heterogeneities of mantle
55 origin inherited from the initial differentiation of the mantle.

INTRODUCTION

58 Subduction zones contribute significantly to Earth's geochemical cycle. Subducted plates return high
59 quantities of lithophile and especially volatile elements to the mantle. Some of the material is recycled
60 deep into the mantle, yet most of it returns to the crust and atmosphere within subduction zones
61 (Sadofsky et al., 2007; Bebout, 2014; Zellmer et al., 2015). Volatiles released from subducting slabs
62 may induce and significantly control mantle partial melting. The depth and rates at which volatiles are
63 released from subducting oceanic plates largely depends on slab thermal state (Manning, 2004; Rüpke
64 et al., 2004; Zellmer et al., 2014). Melts that form in subduction zones contribute to the growth of the
65 continental crust (Hawkesworth et al., 2019). Volatiles carried by and released from these melts have
66 a major impact on atmosphere composition and thus climate and they crucially control the explosivity
67 of volcanic eruptions (MacDonald et al., 2000; Robock, 2000; von Glasow et al., 2009; Roberts et al.,
68 2009). Along-arc variability in melt/magma and volatile fluxes, lava and cumulate geochemistry and
69 petrology, crustal structure and thickness are commonly strikingly large, with very abrupt variations
70 over the scale of only tens of kilometres and between tightly spaced volcanic centers (Sadofsky et al.,
71 2007; Turner and Langmuir, 2015; Melekhova et al. 2015). Considering these parameters on the arc-
72 scale is thus crucial for resolving their interplay.

73 The Lesser Antilles arc, related to the westward subduction of the North and South American plates
74 under the Caribbean plate, is one the most-studied arcs in the world, for which extreme along-arc
variation in magma and crustal parameters has been documented (Brown et al., 1977; MacDonald et al., 2000; Melekhova et al., 2019; Cooper et al., 2020). The overall lava production rate for the Lesser Antilles (162 km³ km⁻¹ My⁻¹; Jicha and Jagoutz, 2015) is considered low when compared with that of other intra-oceanic arcs such as the Izu arc (220 km³ km⁻¹ My⁻¹) or the Aleutians (211 km³ km⁻¹ My⁻¹), but it is higher than for the Tonga-Kermadec arc (157 km³ km⁻¹ My⁻¹) (Gill, 1981; MacDonald et al., 2000; Stern, 2010; Jicha and Jagoutz, 2015). Lava and cumulate geochemistry and petrology have been studied at some locations along the arc, revealing variable maturity of the plumbing system with more or less facility of melt to percolate through the mush (Cooper et al., 2016; Camejo-Harry et al., 2018). Volatile fluxes are less well constrained, particularly for halogens. Studies to date have primarily focused on individual volcanic centers and/or limited element suites (e.g. Gurenko et al., 2005; Bouvier et al., 2008, 2010; Balcone-Boissard et al., 2010, 2018; d'Augustin et al., 2020; Cooper et al., 2020) and on other subduction zones worldwide (Wallace et al., 2005; Sadofsky et al., 2008; Rose-Koga et al., 2014). They show the potential variability of fluid origin and content but are rarely correlated with major and trace elements. For the Lesser Antilles, recent studies have revealed crustal structure at unprecedented detail, using geophysical data and cumulate petrology (Schlaphorst et al. 2018; Melekhova et al. 2019). Melt inclusion studies have shed light onto volatile budgets and transcrustal magma evolution (Métrich and Wallace, 2008; Moune et al., 2012; Mercer and Hofstra, 2020). The diverse character of the arc in terms of its eruptive products (Brown et al., 1977) and its highly variable, well-characterized crustal structure make the Lesser Antilles arc a prime target for further studying the roles of volatiles in controlling magma production, crustal magma storage and differentiation, and their link to crustal structure.

In this study, we present a comprehensive compositional dataset for glassy melt inclusions (major-, trace- and volatile elements, H₂O-CO₂-S-F-Cl-Br) for selected eruptions of the past 60,000 years across the Lesser Antilles arc (from Montserrat, Guadeloupe, Dominica, Martinique, St. Lucia, St. Vincent). Our sample set comprises silica-rich eruptive products. We use the melt inclusion compositions to reconstruct pre-eruptive conditions and especially pre-eruptive magma storage and degassing levels. These provide new constraints for the interpretation of crustal structure as
reconstructed through geophysical surveys and cumulate petrography. We thus present a rare, detailed arc-scale picture of volatile abundances, compositional variation and fluxes that we link to source heterogeneities, variable magma flux and crustal growth rates, crustal magma plumbing systems.

107 GEOLOGICAL CONTEXT

108 The Lesser Antilles arc is an active, mature intra-oceanic arc that stretches for ~850 km, resulting
109 from the oblique (westward) subduction of the north and south American Plates beneath the
110 Caribbean Plate (Fig. 1). The arc has one of the slowest subduction rates on Earth (2-4 cm y⁻¹),
111 probably leading to one of the lowest subduction zone magma production rates (Wadge, 1984).
112 Along-arc variation and location of magma production, and consequently the potential for magma
113 storage/accumulation, may relate to the segmentation of the slab and variation in the dip-angle of the
114 Wadati-Benioff zone (Wadge and Shepherd, 1984; Wadge, 1986). Magmatism in the Lesser Antilles
115 started in the Eocene or earlier, continuing today with active volcanic centers on most of the islands.
116 The arc has a broadly convex geometry. Since the Pleistocene, volcanic activity has occurred in three
117 distinct segments (Fig. 1): (i) in the northern segment from Saba to Montserrat; (ii) in the middle
118 segment from Guadeloupe to Martinique; and (iii) in the southern segment from St. Lucia to Grenada.
119 The northern part of the arc shows two branches: the external arc (Eocene to mid-Oligocene) and the
120 internal arc (Miocene to recent). The switch from the external to the internal arc resulted from the
121 oblique subduction of an aseismic ridge (Barracuda ridge), which blocked the active subduction (at
122 the outer arc composed of the oldest islands like Anguilla, Barbuda) and changed the dip of the
123 subducting plate (Bouysse & Westercamp, 1990). This caused the westward displacement of
124 volcanism and crust formation, which recommenced at ~22 Ma after a 7 million years hiatus. In the
125 southern part of the arc, volcanism has been continuously active. A new compilation of marine
126 magnetic anomaly and seismic data proposes a revised tectonic model for the eastern Caribbean
127 including arc migration in both direction (Allen et al., 2019). The model proposes two phases of back-
arc spreading and eastward-arc migration toward the incoming Atlantic and a third phase of arc migration to the west subdividing the earlier back-arc basin on either side of the present-day Lesser Antilles arc. This feature makes the Lesser Antilles arc the first example of regional multidirectional arc migration in an intra-oceanic setting.

Volcanoes on the northern group of islands, from Saba to Montserrat, have mostly erupted andesite with minor amounts of dacite and basalt. Volcanoes on the central group of islands, from Guadeloupe to St. Lucia, have also mostly erupted andesite, but also basalt, dacite and rare rhyolite, showing the highest magma production rates of the arc. Volcanoes on the southern group of islands, from St. Vincent to Grenada, have dominantly erupted basalt and basaltic andesite. Erupted basalts with near-primary compositions vary widely from low-K tholeiites (north) to alkaline basalts (central part) and silica-saturated basalts (south) (Macdonald et al., 2000). The origin of the wide range of primary and fractionated magma compositions remains debated, but they may be due to magma source variation, variable fluid input, and/or variable differentiation or crustal contamination (Gill, 1981; Zellmer et al., 2014; Rustioni et al., 2021; Labanieh et al., 2010, 2012; Plank, 2014; Teng et al., 2016). In the southern part of the arc, mainly clastic sediments are subducted, deriving from the South American continent, whereas in the northern part, submarine highs and pelagic marine are subducted (Faugères et al., 1993; Carpentier et al., 2008; Labanieh et al., 2012). Fluid inputs may come from various sources, including sediments, crust or mantle. Serpentine has been proved to be the dominant supply of water in the central part of the arc (Cooper et al. 2020).

Crustal differentiation – and thus the architecture of the crustal magma plumbing systems – has long been recognized to vary along the arc, between various volcanic centers, and through time, given that not only lava compositions, but also plutonic xenolith mineralogy is highly variable (Arculus, 1980; Macdonald et al., 2000; Cooper et al., 2016, 2019; Camejo-Harry et al., 2018). Recent geophysical and petrological studies have revealed crustal and magma system structure of the arc in unprecedented detail (Schlaphorst et al., 2018; Melekhova et al., 2019), suggesting an upper crust ~<6 km thick, a variably thick middle crust between ~3 and 32 km thick, and a lower crust between ~5 and 37 km thick. Based on along-arc cumulate petrography and local melt inclusion studies, main magma storage zones are inferred to have variable position and vertical extent. All islands appear to have magma
156 storage zones at or near the boundary between upper and middle crust and most (except for
157 Guadeloupe), while most are inferred to also have deeper magma storage zones within the middle
158 crust or near the middle-lower crust boundary. The degree of crustal contamination appears variable
159 both along the arc and between different volcanic centers of individual islands (Davidson, 1987; van
160 Soest et al., 2002).

162 We have studied samples from Montserrat, Guadeloupe, Dominica, Martinique, St. Lucia and St.
163 Vincent, including samples from ten volcanic centers and 23 explosive eruptions, as summarized in
164 Table 1. Further details on the eruptive centers and their eruptive history are provided in
165 Supplementary file S1.

SAMPLES AND ANALYTICAL METHODS

170

Samples

171 Most of our samples were collected during field campaigns performed by G. Boudon (St. Vincent), G.
172 Boudon and A. Le Friant (St. Lucia), G. Boudon, J.-C. Komorowski and H. Balcone-Boissard
173 (Guadeloupe), G. Boudon and H. Balcone-Boissard (Dominica, Martinique). Samples from July 1997
174 eruptive phase of Soufrière Hills, Montserrat were kindly donated by the Montserrat Volcanological
175 Observatory. Samples studied are pumice samples from: (1) Montserrat, from pyroclastic density
176 currents resulting from collapses of short-lived, sustained sub-Plinian or vulcanian columns that
177 occurred in September 1996 and July 1997 during the 1995-2010 eruption of Soufrière Hills, (2)
178 Guadeloupe, the fallout deposits: from the large pumiceous Pintade eruption (42 ka) and the 1530 AD
179 Sub-Plinian eruption of the Grande Découverte- Soufrière volcano; the Ajoupa Plinian eruption of
180 Mont Caraïbes, (3) Dominica, the fallout deposit from a vulcanian eruption of Plat Pays Volcanic
181 Complex, (4) Martinique, the fallout deposits from four of the last Plinian eruptions: P1 (1348±50 cal
182 AD) P2 (314±69 cal AD), P3 (113±85 cal AD), and P5 (2542±80 cal BC) of Montagne Pelée, (5) St.
183 Lucia, the fallout deposit from one of the eruptive events of Choiseul (~39 ka) and Belfond (~24 ka) and (6) St. Vincent: from pyroclastic density currents of the May 7th 1902 eruption and from a similar eruption dated at 1477 cal AD of the Soufrière volcano. The samples were selected to specifically address the silica-rich magma of each volcano. To also have data on the southern part of the arc, where silica-rich compositions of eruptive products are rare to absent, we selected samples of a well-known eruption (St. Vincent, 1902) with basaltic andesite eruptive products, but silica-rich melt inclusions (Table 2, Fig. 2).

190

191

## 192 Sample preparation

193 Several unaltered pumice or scoriae fragments from each eruption were gently crushed to produce coarse powders (with clast sizes of up to 3 mm) to avoid breaking crystals. Glassy matrix and phenocrysts were then separated by sieving the powders into different size fractions (125-250 µm; 250-355 µm; 355-500 µm). Each size fraction was first washed in an ultrasonic bath to remove fine particles, and minerals were then separated by density in water.

198 Euhedral crystals were most abundant in the 250-355 µm size fraction, and in the 355-500 µm size fractions. Orthopyroxene (opx) (Fig. 3a to e), clinopyroxene (cpx) (Fig. 3f), plagioclase (plag) (Fig. 3g) and magnetite (mgt) (Fig. 3h) were handpicked under a binocular microscope, and mounted in epoxy resin. The mounts were roughly polished using sandpaper with decreasing grain size and finally polished using 0.3 µm, Al₂O₃-impregnated lapping films to expose melt inclusions at the surface (Fig. 3). Samples were carbon- or gold-coated for subsequent analyses, where samples and standards were coated together to avoid potential analytical bias caused by a different coat thicknesses.

205

## 206 Whole-rock compositions

207 Major element compositions of selected pumice powders were analyzed by ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) (Carignan et al., 2001) at CRPG (Centre de Recherches Pétrographiques et Géochimiques, Nancy, France) (Table 2).

210
211 **Melt inclusion characterization**

212 *Light optical microscope observations*

213 At first, melt inclusions were observed by using an optical microscope in transmitted light for
214 documenting their textures (wall shapes, devitrification..) or the presence of post entrapment bubbles
215 or microlites (following the procedure by Cannatelli et al., 2016; Rose-Koga et al., 2021)
216 (Supplementary material S2). This allowed us to exclude MIs that would have been problematic for
217 analysis and to concentrate our effort on bubble-free melt inclusions, as further explained below.

218 *SEM observations*

219 Crystal mounts were then imaged using the Scanning Electron Microscope (SEM) at the “Institut des
220 Sciences de la Terre de Paris”, Sorbonne Université (Paris) to locate melt inclusions (MIs). At this
221 stage, composition was characterized by Energy-dispersive X-ray Spectroscopy (EDS) to avoid
222 analysing partly crystallised or mineral-filled inclusions during subsequent, fully quantitative analysis
223 in opaque minerals. The characterization showed that the melt inclusions have a mean size of ~30 µm
224 (the largest in Dominica, up to 50 µm) and typically ≤20 µm with highly irregular to ellipsoidal
225 shapes (Fig. 3, Supplementary material S2). The EDS characterization identified individual inclusions
226 as targets for fully quantitative analyses (Supplementary material S3).

227

228 *Electron probe microanalysis (EPMA)*

229 Major- and minor-element compositions (Si, Ti, Al, Fe, Mg, Mn, Ca, Na, K, P, F, and Cl) of MIs and
230 host minerals were determined using a CAMECA SX five electron microprobe (EPMA) at Camparis
231 (Paris). Concentrations of Si, Ti, Al, Fe, Mg, Mn, Ca, Na, K, and P were analysed at an acceleration
232 voltage of 15 keV and a beam current of 10 nA, with a spot size of 5 µm. Peak counting time was 10 s
233 for all elements except for Na (5s). Na was analysed first to minimize loss by volatilisation under the
234 electron beam. The beam was defocused to a 10 µm diameter to minimize volatile loss for all glass
235 analyses, while it was focused for all mineral analyses. To determine the F and Cl concentrations of
236 the glasses, a second set of analysis was subsequently performed at an acceleration voltage of 15 keV
237 and a beam current of 80 nA. Counting time was set to 120 s for F and to 60 s for Cl to achieve low
detection limits (<~100 and 20 ppm, respectively). For inter-calibration of EPMA sessions, three internal standards were analysed at the same conditions as the samples (CO5, LIP, LGM, *Balcone-Boissard et al., 2008*) (Supplementary material S4).

241

Analysis of volatile elements (H₂O, CO₂, S, Br) by secondary ion mass spectrometry (SIMS).

The concentrations of H₂O, CO₂, Br, and S in MIs were measured at the Centre de Recherches Pétrographiques et Géochimiques (CRPG) of Nancy (France), using an IMS 1280 HR2 Secondary Ion Mass Spectrometer (SIMS), following the methodology of Bouvier *et al.* (2010) and Métrich and Deloule (2014) (for H₂O, CO₂, and S), and Cadoux *et al.* (2017) (for Br). The beam size was 10-15 µm. Calibration curves for H₂O, CO₂, S, and Br were calculated using best fit regressions for [H₂O] versus ¹⁶OH/¹⁸O, [CO₂] versus ¹²C/¹⁸O, [S] versus ³²S/¹⁶O, and [Br]/[SiO₂] versus ⁸¹Br/²⁹Si¹⁶O₃, respectively, using reference materials from Shishkina *et al.* (2010), Jochum *et al.* (2006), Métrich and Deloule (2014), Behrens *et al.* (2004) and Kendrick *et al.* (2012) (Supplementary material S4).

Raw data were normalized to oxygen because the oxygen content is approximately constant in all magma compositions from basalts to rhyolites, regardless of the silica content. The signal is thus less compositionally dependent than if it was normalized to silica (Bouvier *et al.*, 2010; Métrich and Deloule, 2014). The Br calibration curve was normalized to silica content (previously measured by EPMA) to cast off silica content dependency. The regression curve for H₂O was fitted by a polynomial, whereas the CO₂, S, and Br curves were fitted by a linear regression. For each volatile species, sample concentrations were within the standard compositional range (Supplementary material S4-2). For the standards, relative standard deviations were 125 ppm for H₂O, 43 ppm for CO₂, and 1 ppm for sulphur and Br. We monitored signal stability during the analysis for every volatile element.

Melt inclusion trace-element compositions were determined by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at the Institut des Sciences de la Terre d'Orléans (CNRS-ISTO), using a RESOlution SE 193 nm excimer laser ablation system with a Laurin Technic cell coupled to an Agilent 8900 QQQ quadrupole mass spectrometer. Instrument parameters and operating
conditions are summarized in Supplementary material S4. The analytical spot size varied between 10 and 14 µm. Isotopes analysed were ⁶Li, ⁷Li, ²⁷Al, ⁴³Ca, ⁴⁴Ca, ⁵⁹Co, ⁶⁰Ni, ⁸⁵Rb, ⁸⁸Sr, ⁸⁹Y, ⁹⁰Zr, ⁹³Nb, ¹³⁷Ba, ¹³⁹La, ¹⁴⁰Ce, ¹⁴¹Pr, ¹⁴⁶Nd, ¹⁴⁷Sm, ¹⁵³Eu, ¹⁵⁷Gd, ¹⁵⁹Tb, ¹⁶³Dy, ¹⁶⁵Ho, ¹⁶⁶Er, ¹⁶⁹Tm, ¹⁷²Yb, ¹⁷⁵Lu, ¹⁸¹Ta, ²³²Th, and ²³⁸U. NIST610 was used as the external standard and NIST612 and BCR-2G as quality controls (Supplementary material S4). All raw data were processed using “Glitter” (“GEMOC Laser ICP-MS Total Trace Element Reduction”, version 4.4.4; van Achterbergh et al. 2001) with CaO as the internal standard. For the external standard NIST610, data regression showed low RSDs of ≤1.5 for all elements (Supplementary material S4). For quality controls NIST612 and BCR-2G, RSDs were <4 and <11, respectively (Supplementary material S4). Bias was mostly within 4% (Supplementary material S4). Standard errors on individual sample analyses are reported in Supplementary material S4 and are indicated in figures.

278 Test of equilibrium for MI mineral host couples

279 Melt inclusions may provide valuable information on pre-eruptive melt composition, but they may seal late or undergo post-entrapment modification, including post-entrapment crystallization (PEC), involving growth of the host crystal or daughter crystals, leakage or decrepitation, diffusion of volatile species through the host crystals, or partitioning of volatile species into shrinkage bubbles (e.g., Wallace 2005; Esposito et al., 2014; Rose-Koga et al., 2021). The intensity of these processes depends on the host mineral and the post-entrapment evolution (time scales, conditions) (e.g., Barth and Planck, 2021; Lloyd et al., 2012; Rose-Koga et al., 2021). To assess equilibrium between MIs and their hosts and the degree of PEC, we have used the published partition coefficients (Kd) for each host (Table 1, 3). The solid-liquid partition coefficient of an element X (noted as Kd (X) solid-liq) describes the ratio of the concentration of an element in the solid (crystal) to the concentration in the liquid (silicate melt). Equilibrium was assessed using Kd (Fe-Mg) Opx-liq = 0.4805 – 0.3733[Si] (liq) (Putirka, 2008), Kd (An-Ab) plag-liq = 2.46 ±0.09 for Pl (Solaro-Müller 2017), lnKd (Fe-Mg) cpx-liq = -0.107-(1719/T(Kelvin)) (Putirka, 2008) and Kd (Mn) (mgt-liq) = 0.34 ±0.14 (Sievwright et al., 2020). Hereafter we only consider MIs with less than 8% of PEC for pyroxene, 20 % for plag (as they are more prone to modifications) and 10% for magnetites. Pyroxenes, in particular cpx, have a

relatively high potential for preserving initially trapped melt H₂O content compared to feldspar (Lloyd et al., 2016). In our dataset,90% of the MIs analysed in pyroxenes were at equilibrium, similarly to magnetite (85%). On the contrary, 70% of the MIs were at equilibrium in feldspars.

Recent studies have shown that up to 90% of the CO₂ budget in MIs can diffuse into shrinkage bubbles because of the low solubility of CO₂ in silicate melts (Robidoux et al., 2018). Here, we did not quantify the CO₂ content of the shrinkage bubbles (e.g. using Raman spectroscopy). Analysing only MIs without obvious bubbles and microlites bears the risk that the initially most volatile-rich MIs are unsampled, as they are most likely to have exsolved volatiles and partially crystallized during decompression (Hartley et al., 2014; Moore et al., 2015). Equally important is that MIs may experience selective loss of H₂O (in the form of H⁺), which may take place during intermittent magma storage, during magma ascent, or syn- to post-eruptive, where MIs are thought to partly re-equilibrate (lose H₂O) within hours to days (Plank et al., 2013; Ingrin & Blanchard 2006; Lloyd et al., 2016). To reconstruct the pre-eruptive volatile contents as best as possible (i.e. to minimize selective loss of H₂O on our dataset), we only analysed the largest possible melt inclusions (> 20 µm in size) within large phenocrysts (315 – 500 µm in size) of the largest eruptive clasts (Chen et al., 2011). All our samples are pumice (Table 1), which experienced rapid ascent from pre-eruptive storage to the surface, where they were rapidly quenched.

312 CO₂-H₂O-solubility pressure relations

To estimate MI equilibration pressures, we have used their CO₂-H₂O compositions and the widely applied MagmaSat software (Ghiorso and Gualda, 2015) to calculate saturation pressures for each individual MI, using the measured major element compositions, an assumed fO₂ of ~NNO +1 (Pichavant et al., 2018) and the temperatures calculated from mineral-melt thermometry (Supplementary information S5). We have assumed volatile saturation and calculated a range of equilibration temperatures using several mineral-melt thermometers of Putirka (2008) (equations 24a (Plag-liq), 28a (Opx-liquid), 33 (Cpx-liquid) and 37 (Opx-Cpx)) here for Martinique. For the other studied eruptions, we used literature data : for MIs from Montserrat (Barclay et al., 1998, Couch et al., 2001, Murphy et al., 2000) giving a temperature 840-870 °C, and up to 1050 °C, for Guadeloupe,
the temperature of the mush zone for the differentiated melt is comprised between 825-875 °C (Pichavant et al., 2018; Metcalfe et al., 2022), for Dominica, a temperature range of 850-900 °C for ignimbritic eruptions (Balcone-Boissard et al., 2018) and Plinian eruptions (d'Augustin et al., 2020), for St. Lucia, an average equilibration temperature of 810-850°C for differentiated melt, and for MIs from St. Vincent, an average equilibration temperature of 1020°C (this study). In addition, we have used the “VolatileCalc” solubility model of Newman and Lowenstern (2002) to graphically represent the data. In addition to the CO₂-H₂O saturation pressures, we have also estimated equilibration pressures using H₂O-Cl solubility relationships (Webster et al., 1999).

## 331 RESULTS

For each of the 23 considered eruptions (Table 1), moving from island to island from North to South, we present whole-rock major element compositions (Table 2) and MI major-, minor- and trace-element compositions including volatiles and halogens (Table 3, 4, 5 and Supplementary material S6 to S10). Following this, we present a summary of the key compositional characteristics and their variation along the arc. All MI compositional data are presented in Figures 4 to 15.

#### 341 Montserrat (Soufrière Hills volcano)

Whole-rock compositions of the studied Montserrat samples are andesitic (Fig. 2a). All analysed MIs are rhyolitic, with SiO₂ contents ranging from ~76 to 78 wt % and a total alkali content (Na₂O+K₂O) of 5.0-5.5 wt% (K₂O ~1.5-2.0 wt%), corresponding to the medium-K series (Figs. 2a, 4a,; S6). The MIs have some of the most differentiated major element compositions in our dataset (Fig. 2a, 4a,, S6). They have relatively homogeneous H₂O contents ranging from ~1.7 to 3.2 wt %, show significant variations in CO₂ content, from tens of ppm to ~2550 ppm, and low S contents (<30 ppm) (Fig. 5a, b,

c; S7, S8). Fluorine concentrations in MIs fall into a narrow range (100-250 ppm), while Cl contents are variable and relatively high (~1000 and up to 4000-4500 ppm) (Figs. 5d, e). Br contents are low and moderately variable (~3-9 ppm) (Fig. 5f). Trace elements patterns of the MIs exhibit a positive anomaly in Ba, and a negative anomaly in Nb-Ta (Fig. 6a). They show a slight enrichment in light Rare Earth Elements (LREEs, La, Ce, Pr, Nd) compared to middle REEs (MREEs, Sm, Eu, Gd) and high REEs (HREEs, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) (Fig. 6a). The MI compositions (Table 5) are further characterized by an enrichment in La relative to Ce (Fig. 6a; Table 3), high Ba/La ratios of ~25 (Fig. 7a), low Y contents (12-20 ppm) (Fig. 7b), low Sr contents (114±20 ppm) (Fig. 7c), low Rb contents (39±7 ppm) at intermediate Zr contents (145±27 ppm) (Fig. 7d), and intermediate Li contents (< 40 ppm) at low H₂O contents (< 3 wt%) (Fig. 7e). The MIs show moderately high to high La/Sm ratios (5-9) (Fig. 8a), nearly invariant Ba/Th ratios of 73 ±3 (Fig. 8a), constant U/Th ratios of ~0.32 (Fig. 8b), among the highest Ba/Nb (80-120) and Th/Nb (1 - 1.5) ratios (Fig. 8c) and low Dy/Yb ratios (1±0.2) (Fig. 8d).

361

## Guadeloupe (GDS-1530AD and Pintade eruptions- and Monts Caraïbes volcanoes)

Whole-rock compositions of Guadeloupe samples are evolved basaltic andesite to andesite (Fig. 2b). All MIs are rhyolitic (in most 1530AD samples) or dacitic (in Monts Caraïbes, Pintade and some 1530 AD samples). MIs show a fairly large range in SiO₂ from ~67 to 75 wt%, with variable alkali content (Fig. 4b, S6). All MIs from 1530 AD samples have an alkali content between ~5-6 wt% (Fig. 2b). MIs from older eruptive products (Pintade and Monts Caraïbes eruptions) are characterized by a larger range of alkali contents, extending to lower values (~2.1-6 wt%) (Fig. 2b). All MIs from the Pintade and 1530 AD samples belong to the medium-K series (~1.2-2.0 wt%), contrary to those of the Monts Caraïbes eruption, which belong to the low-K series (with a mean K₂O of ~0.5 wt%), each falling on linear differentiation trends (Fig. 4b). Water contents in MIs show a large range from ~0.5 to 5.9 wt % H₂O in the products of the Mont Caraïbes and Pintade eruptions, while MIs from 1530AD eruption have <3.5 wt% H₂O (Fig. 5a; supplementary material S7). Carbon dioxide contents in MIs show a large range. The majority of values are below 1000 ppm, yet some higher concentrations have been

detected (up to 4570 ppm) (Fig. 5b). Sulfur content in MIs is low (<~200 ppm) with a mean of 69±33 ppm (Fig. 5c). Halogen contents show large ranges for F (70-1040 ppm) and Cl (310 up to 3230 ppm), yet a narrow range for Br (at ~0-8 ppm) (Figs. 5d, e f). The MI trace element patterns exhibits a positive anomaly in Ba, and a negative anomaly in Nb-Ta (Fig. 7a). The patterns are similar for MIs from the Pintade and Monts Caraïbes eruptions, and also for MIs from the 1530 AD eruption, but the compositions of the latter are shifted to higher values (Fig. 6a). All MIs show a moderate enrichment in LREEs compared to MREEs and HREEs (Fig. 6b. Monts Caraïbes MIs show a positive anomaly in Sr, contrasting with the negative Sr anomalies of MIs from the other eruptions (with 200-277 ppm Sr and <200 ppm Sr, respectively). The MIs are characterized by an enrichment in Ce (32±10) relative to La (13 ±4) (Fig. 6b; Table 3, 5), low Ba/La ratios (10-15; Fig. 7a), low to high Y contents (8-58 ppm) (Fig. 7b), variable Sr contents (Fig. 7c), relatively low Rb contents (9-117 ppm), low to high Zr contents (34-233 ppm) (Fig. 7d), and moderately low to low Li contents (<35 ppm) (Fig. 7e). MIs show low La/Sm ratios (2-3) and variable Ba/Th ratios between 46 and 112 (Fig. 8a), a constant U/Th ratio of 0.32 (Fig. 8b), the lowest Ba/Nb (25-60) and Th/Nb (0.3 – 1) ratios (Fig. 8c) and moderately high Dy/Yb ratios of 1.5±0.2 (Fig. 8d).

391 Dominica (Plat Pays Volcanic Complex, PPVC)

Whole-rock compositions of Dominica's PPVC eruption products, as for other volcanic centers, are andesitic to dacitic (Fig. 2c). All PPVC MIs are rhyolitic with an SiO₂ content of ~75.4 to ~77.8 wt% and a total alkali content (Na₂O + K₂O) of ~5 to 8 wt% (Fig. 2b). They belong to the medium-K series, and they are as differentiated as other MIs from Dominica in terms of major element compositions (Fig. 4c, S6). The MIs have homogeneous, yet low H₂O contents of 2.4±0.2 wt% (except for one value at 0.5 wt%; Fig. 5a), which contrasts with their relatively high CO₂ content, which is mostly higher than 1500 ppm (Fig. 5b). Melt inclusion S contents are very low (< 20 ppm; Fig. 5c). The F and Cl contents of MIs are low (<780 ppm and 1020-1890 ppm, respectively), while Br contents are variable (from 2.4 to 7.6 ppm) (Fig. 5d to f). The trace element patterns are similar for MIs from all eruptive centers (Fig 6c). All PPVC MIs exhibit a positive anomaly in Ba, and they show a moderate enrichment in LREEs compared to HREEs (Fig. 6c). The MIs are characterized by a large

The MIs also show high La/Sm ratios (4.4-5) yet homogeneous Ba/Th ratios with a mean of 57 ±2 (Fig. 8a), constant U/Th ratio of ~0.32 (Fig. 8b), high Ba/Nb (100-120) and Th/Nb (1-2) ratios (Fig. 8c) and Dy/Yb ratios of 1.2±0.3 (Fig. 8d).

Whole-rock compositions of the studied Martinique eruptive products are mostly andesitic, but include one basaltic andesite (Fig. 2d). The MIs have nearly exclusively rhyolitic composition with ~73.5 to ~77.3 wt% SiO₂, showing a relatively large range of total alkali contents (Na₂O+K₂O) between ~3.8 and 6.5 wt% (Fig. 2d). They classify as medium-K series, falling on a linear differentiation trend (Fig. 4d, S6). The MIs show a large range in H₂O, with up to ~7 wt% (Fig. 5a), a large range in CO₂ (up to 4867 ppm, Fig. 5b), and moderately low S contents (mostly < 200 ppm, Fig. 5c). Halogen contents (Fig. 5d to f) are variable for F (65-760 ppm) and Cl (~618-2867 ppm), and moderately variable for Br (0.7 – 10 ppm). The MI trace element patterns of all studied eruption products from Martinique (Fig. 6d) exhibit a positive anomaly in Ba and a negative anomaly in Nb-Ta. They also show a moderate enrichment in LREEs compared to HREEs. Melt inclusion compositions are characterized by a large range in Ce (21-78) relative to La (10-35) (Fig. 6d; Table 3, 5), variable but mostly low to moderately low Ba/La ratios between 12 and 28 (Fig. 7a), low to high Y contents (14-60 ppm, Fig. 7b), high to low Sr contents (162 ±48 ppm, Fig. 7c), low to moderate Rb contents (26-153 ppm) and low to high Zr contents (49-249 ppm) (Fig. 7d), and relatively high Li contents (20-80 ppm, Fig. 7e). The MIs show variable, but mostly low to intermediate La/Sm ratios (mostly 2-5.8) at low to high Ba/Th ratios of ~73 ±17 (Fig. 8a), relatively variable U/Th ratios of ~0.3 ±0.1 (Fig. 8b), mostly low Ba/Nb ratio (50-80) for low Th/Nb ratio (0.6 – 1.2) (Fig. 8c) and low to high Dy/Yb ratios of 1.2±0.3 (Fig. 8d).
431 St. Lucia (SVC)

432 Whole-rock compositions of the St. Lucia samples are dacitic (Fig. 2e). The composition of the MIs is
433 the most silica-rich in our sample set with ~77 to 79.5 SiO₂ and with a total alkali content (Na₂O +
434 K₂O) content of 6 wt% (Fig. 2e) with K₂O contents up to ~4.0 wt%, belonging to the high-K series
435 (Fig. 4e, S6). The MIs have low H₂O contents (< 3 wt%, Fig. 5a), even at the highest K₂O contents (4-
436 4.3 wt%), and they show relatively minor variation in CO₂ content (150 – 1455 ppm, Fig. 5b), and no
437 detectable S content (Fig. 5c). Halogen contents (Fig. 5d to f) are characterized by homogeneous, low
438 F (255-355 ppm) and low Cl contents (<525 ppm). Bromine contents were not measured successfully.
439 Only glass in an embayment in plagioclase has been analysed for trace-element compositions due to
440 the small size of the MIs (Fig. 6e). The embayment shows high Ba/La (Fig. 7a), low Y content at high
441 Th (Fig. 7b), low Sr (Fig. 7c), high Rb content at low Zr content (Fig. 7d), and intermediate Li content
442 (60 ppm, Fig. 7e). The embayment glass also has low Ba/Th at high La/Sm (Fig. 8a), a U/Th ratio of
443 ~0.4 (Fig. 8b), a high Ba/Nb (120) ratio at a high Th/Nb (2.2) ratio (Fig. 8c), and high Dy/Yb (1.7)
444 (Fig. 8d).

445

446 St. Vincent (Soufrière volcano)

447 Whole-rock compositions of the studied St. Vincent samples are basaltic andesitic (Fig. 2f). MIs from
448 the 1902 eruption are dacitic with SiO₂ between 65-68 wt% and with a total alkali content (Na₂O +
449 K₂O) content of 5-6 wt% (Fig. 2f). Melt inclusions of the 1477 AD eruption are rhyolitic with SiO₂
450 contents of ~75 wt% at an alkali content of ~6.7-6.9 wt%. Melt inclusion compositions fall on the
451 boundary between the medium and low-K series with K₂O contents of ~0.8 and ~1.4 wt% for dacitic
452 and rhyolitic MIs, respectively (Fig. 2f, S6). They show relatively homogeneous major element
453 compositions (Fig. 4f). Melt inclusion volatile contents (Fig. 5; S7, S8) differ for the 1477 AD (only 2
454 values) and for the 1902 eruptions. The silica-rich, 1477 AD MIs are volatile poor with H₂O < 1.4
455 wt%, CO₂ <300 ppm (except for one MI with the highest CO₂ value, 3230 ppm), and they have very
456 low S (bdl), F < 160 ppm, Cl < 930 ppm, and Br < 1.5 ppm. The 1902 dacitic MIs, in contrast, show
457 moderately high H₂O contents (2.6-4 wt%), variable, low to moderately high CO₂ contents (230-1700
458 ppm), and low to moderately high S contents (30-92 ppm). Halogen contents (Fig. 6 d to f) also show
a large range for F (100-520 ppm), Cl (680-1865 ppm) and Br (1.1 – 4.1 ppm). The MI trace element patterns (Fig. 6f) exhibit a positive anomaly in Ba, a negative anomaly in Nb-Ta and a high range in Ce (26±3) and La (10 ±1) (Fig. 6f). There is a slight enrichment in LREEs/MREEs compared to the HREEs. The MIs are further characterized by moderately low Ba/La ratios of ~20 (Fig. 7a; Table 5), a low Y/Th (3) ratio (Fig. 7b), relatively high Sr contents (150±26 ppm, Fig. 7c), low Rb contents (19-28 ppm) and high Zr contents (153-186 ppm) (Fig. 7d), and intermediate to low Li contents (15-25 ppm, Fig. 7e). They also show low La/Sm ratios (2.2±0.1) yet high Ba/Th ratios of 94 ±11 (Fig. 8a), U/Th ratios of ~0.6 ±0.2 (>0.5, Fig. 8b), intermediate Ba/Nb (80-110) and Th/Nb (1 - 1.6) ratio (Fig. 8c) and a high Dy/Yb ratio of 1.7±0.5 (Fig. 8d).

Along-arc silicic MI compositional variation

471

Our MI data presented above are discussed together with data from the literature for comparable
silicic composition where they exist. Data are from Cooper et al. (2020), Mann et al. (2013) and
Humphreys et al. (2009) for Montserrat, Cooper et al. (2020) and Metcalfe (2022) for Guadeloupe,
from Gurenko et al. (2005), Balcone-Boissard et al. (2018), Cooper et al. (2020) and d'Augustin et al.
(2020) for Dominica, from Cooper et al. (2020) and Martel et al. (1998) for Martinique and from
Cooper et al. (2020) for St. Lucia. Here, the most important observations for the different volcanic
centers are:

(1) There is no systematic correlation between MI volatile content and MI major element composition (Fig. 5; supplementary information S8 and S9) or between MI volatile content and host mineral type (supplementary information S9). Concentrations of volatiles are highest in MIs from the central part of the arc, i.e. from Dominica and Martinique and closely followed by those from Guadeloupe, where magma production rates are the highest, as was previously noticed by Cooper et al. (2020) for H₂O concentrations. The less differentiated melts from St. Vincent show high halogen content. The
maximum H₂O content is highest in MIs from Dominica and lowest in MIs from St. Lucia. The CO₂ content is highest in MIs from Martinique, Guadeloupe, and Dominica and lowest in MIs from St. Lucia. The S content is highest in MIs from Guadeloupe and lowest in MIs from Montserrat and St. Lucia. For halogen, the differences are less obvious. The F content is highest in MIs from Guadeloupe and St. Vincent and lowest in MIs from Montserrat and St. Lucia. The Cl content is relatively similar for all islands except for a lower concentration in MIs from St Lucia. The Br content is highest in MIs from Dominica and comparable in MIs from all other islands. Volatile contents are thus variably high for MIs across the arc with no North-South systematic variations. Cooper et al. (2020) suggests that the variable mantle wedge hydration is linked to the heterogeneous distribution of serpentine in subducting mantle lithosphere.

(2) Large Ion Lithophile Elements (LILEs; Rb, Ba, Sr) show no systematic variation with MI major element composition or host mineral type, but they do show variation along the arc depending on the considered island (Fig. 7a). The Ba-La contents of MIs, as an indicator of slab input (Ba enrichment by fluids), are positively correlated (Figs. 6, 7a, 8). The Ba-La compositions of MIs from Guadeloupe, Martinique, and St Vincent fall on one compositional trend, while those of MIs from Dominica, Montserrat and St. Lucia follow a distinctly more Ba-rich trend (Fig. 7a). Melt inclusions from the Monts Caraïbes eruption in Guadeloupe have the highest Sr contents, followed by Martinique, the rest of Guadeloupe, St. Vincent and then Dominica that are less and less Sr-rich (Fig 7c). Such fluid-mobile elements are carried down in subduction zones by hydrous minerals (e.g., amphibole, biotite, phengite, barite, serpentine, brucite, chlorite), and they are released along with hydrous fluids into the mantle wedge during mineral breakdown. The lack of along arc systematic variation of LILEs in erupted magmas indicates variable fluid input from the slab, possible released at different depth (Ribeiro et al., 2013).

(3) The high-field strength elements (HFSE; U and Th) also show no systematic variation with MI major element composition or host mineral type. For all MIs analysed, there is a strong, positive linear correlation for U-Th, as expected for cogenetic magmas (U/Th~0.3; Fig.8b; S10), which passes through the origin. MIs from Montserrat, Guadeloupe, Dominica, and St. Lucia (only one analysis but
describing the same domain with the literature data) have closely comparable U/Th compositions of ~0.3±0.05, while those of Guadeloupe extend from ~0.3 to higher values of ~0.5, which compare to the U/Th compositions of ~0.5 of St. Vincent. Some data that deviate from this correlation may indicate a larger influence of sediment contribution which is variable along the arc (Plank, 2014)

(4) LILEs vs. HFSEs: In Rb vs. Zr compositional space (Fig. 7d), MIs from the different islands show variable compositions and compositional trends. The less differentiated MIs from St. Vincent are Rb-poor, whereas those from Dominica and St. Lucia are relatively Rb-rich. MIs from Montserrat, Guadeloupe and Martinique fall on the same, moderately Rb-rich linear trend. Melt inclusion Y contents are mostly positively correlated with Th contents (except for Th-rich MIs from Dominica), showing linear correlations (Fig. 7b). The Y/Th ratios of MIs decrease from St. Vincent and Guadeloupe over Martinique to Montserrat/Dominica, showing characteristic trends for each island (Fig. 7b). Garnet is the most probable mineral that can scavenge Y from melt (Sisson and Bacon, 1992), suggesting that a low Y content in melt inclusions is related to the presence of significant amount of garnet in the mantle source. For the Lesser Antilles arc, the Y/Th ratio of magmas is a remarkable benchmark along the arc to identify a given volcanic center which may be useful for correlations of on land and sea tephrostratigraphy.

(4) Lithium: Melt inclusion Li content and range vary between volcanic centers of the different islands, yet show no clear North-South variation (Fig. 7e). For the central islands of Dominica and Martinique, MIs have the highest Li contents. Dominica shows the largest compositional range (4 up to 220 ppm), followed by Martinique (22-70 ppm) and St. Lucia (50-70 ppm). The MIs from St. Vincent and the evolved MIs from Montserrat and Guadeloupe have low and a comparatively narrow range of Li concentrations (Montserrat ~15-37 ppm, Guadeloupe ~3-32 ppm, St. Vincent ~12-25 ppm).

## Architecture of the magma plumbing systems
The architecture of the magma plumbing system of a volcano is a parameter of prime importance to understand its behaviour in case of reactivation. Here, based on a series of samples representative of the silicic magmas emitted from nine volcanic centers along the Lesser Antilles arc, we provide a detailed model for active, intermittent magma storage zones beneath the various islands along the arc.

We use the MIs compositions which can be entrapped at variable pressures (in mantle to crust) within relatively incompressible phenocryst hosts (Lowenstern, 1994) as key witnesses of magma history, from magma generation and storage to emission. Crystals in magma ponding zones may entrap MIs, in which case the MIs should be predominantly located in compositional plateau zones. Crystals transferring in the magma plumbing system, or crystals in magma mixing zones, which may experience rapid variation in intensive parameters, may also entrap MIs, in which case the MIs should be predominantly located along dissolution surfaces or within rapidly formed crystal layers.

Our along-arc dataset includes MIs entrapped in different mineral types (Cpx, Opx, Plag, Mag) and published data for silicic melt inclusions from the arc have the potential to provide an unprecedented record of conditions within the evolved but also within primitive (St. Vincent) magma plumbing systems (Table 3; Supplementary information S6 to 10). The number of mineral host types considered is wide. This could cause variably re-equilibrated MI compositions, but also holds the potential to unravel crystallization conditions for a larger range of magma compositions, pressures and temperatures. As we have carefully considered MI-host mineral equilibrium, we argue that the wide range of MI-host mineral type pairs offers an opportunity to access additional information that may otherwise be lost from the record. We have specifically sampled rapidly erupted pumice, emitted in explosive eruptions that favour fast cooling rate limiting H₂O diffusion from MI to the crystal (Lloyd et al., 2012; Koga et al., 2021), especially in large MIs as most of the studied MIs are (at least 40µm (S2), and with less than 5% of post-entrapment modification, Lloyd et al., 2012). We have moreover selected large crystals (250-350µm), which also have a relatively high probability hosting MIs that have undergone low degrees of post entrapment modification as diffusion distances tend to be large, thus limiting rapid volatile loss. Melt inclusions from explosive eruptions may be quenched with sufficient speed such that post-entrapment crystallization, shrinkage bubble formation, and volatile exsolution into bubbles are kinetically hindered (Clocchiatti 1975; Tait, 1992; Lowenstern, 1994;
Rasmussen et al 2020). The data set highlights that MIs trapped in pyroxenes are less prone to post-entrapment modification compared to those trapped in feldspars (Table 3). For silicic melts, volatile saturation in silicate melts is strongly controlled by pressure, and significantly less so by temperature and melt composition (Wallace and Anderson, 1999).

574

Providing a careful selection of MI volatiles (H₂O, CO₂, Cl) concentrations and evaluating volatile saturation of the system, we can thus constrain pressures and depths of magma storage, which are an order of magnitude more sensitive than mineral barometric estimates based on volcanic phenocrysts (Wallace et al., 1999; Gualda and Ghiorso, 2014; Erdmann et al. 2014, 2016; Cannatelli et al., 2016; Koga et al., 2021).

580

Melt inclusion volatile contents as pressure probes

581

Magma storage pressures can be estimated from MI volatile contents (Wallace et al. 1999; Schmitt 2001; Liu et al. 2006). The only unequivocal evidence for volatile saturation in a magma containing H₂O and CO₂ is a decrease in CO₂ content of melt inclusions with increasing degree of differentiation, as revealed, for example, by increasing contents of incompatible trace elements (Wallace et al. 1999).

This is because gas loss, whether driven by isobaric volatile-saturated crystallization or by decompression of volatile-saturated magma, will always drive CO₂ preferentially into the vapor phase, leading to its preferential depletion, relative to H₂O, in the melt. In cases where the melt is not volatile-saturated, the estimated pressure based on volatile saturation will underestimate the true storage pressure. Note that the presence of gas bubbles in a melt inclusion does not necessarily indicate that the magma was gas-saturated as bubbles can also form by shrinkage during cooling (see Cannatelli et al., 2016 and Rose-Koga et al., 2021, for a review).

The H₂O and CO₂ contents of the Lesser Antilles MIs are at the same K₂O content, yet showing significant or weak negative correlation for K₂O and H₂O, or CO₂ (Supplementary data S8). This indicates that the H₂O and CO₂ variations cannot be explained by incompatible behaviour during fractionation at volatile under-saturated conditions (which should produce positive correlation trends).
It is thus possible that the variable H₂O/K₂O and CO₂/K₂O compositions record (1) degassing-driven crystallization (which should produce negative correlation trends for H₂O/K₂O) (Blundy and Cashman, 2008), or (2) entrapment/sealing of MIs with relatively homogeneous K₂O composition at highly variable pressures and thus throughout significant portions of the crust, and/or (3) post-entrapment loss of the volatiles without (kinetically hindered) post-entrapment crystallization (leaving MI K₂O largely unmodified). Significant post-entrapment loss of H₂O without significant post-entrapment crystallization is possible by diffusion of H⁺ through the host minerals, which has been inferred to re-equilibrate MI compositions over hours to days especially in olivine (Gaetani et al. 2012). Alternatively, we cannot exclude that H⁺ diffusion took place, accounting for the low H₂O and low XH₂O detected for some MIs (< 2 wt%), which is commonly invoked for MIs in olivine (Métrich et al., 2008; Plank et al., 2016; Ruth et al., 2018), and especially for MIs with low XH₂O deviating from decompression-driven degassing paths (Fig. 10); ii) another possible explanation is that CO₂ flushing through the plumbing system took place, which dehydrated the melt and decreased XH₂O like those CO₂-rich for low H₂O content deviating from the closed-system degassing path along isobaric paths (Fig. 9) (Blundy et al., 2010; Caricchi et al., 2018), but such trends would be obvious; iii) the MIs H₂O contents reflect stalling and re-equilibration in the upper magma reservoir or lower conduit, rather than initial entrapment (Mann et al., 2013); such re-equilibration at lower stage in the plumbing system has been previously inferred to explain lower Cl content for pre-eruptive melt than measured in MIs for Montserrat (Villemant et al., 2008). The spread in MI H₂O contents is striking and largest for several of the Dominica and Martinique samples. The large range in MI H₂O contents likely records that MIs were analyzed at variable positions within phenocrysts (at variable distances from crystal cores), where melts with various H₂O contents and thus from various depths within the plumbing system were entrapped. This provides evidence that MIs can be used as pressure probes for magmas, but that their record is incomplete and potentially reset. By combining multiple representations (Figs. 5a, 7e, 9 and 10), we may infer representative magma ponding zones with confidence as shown in figure 11, even if some melt inclusion compositions were modified.

Diffusion of CO₂ through host minerals is, in contrast to diffusion of “H₂O” (H⁺) is extremely slow (Zhang and Ni, 2010), and post-entrapment CO₂ exsolution therefore produces CO₂-filled bubbles. In
case of bubble-bearing melt inclusions between 40 up to 90% of the original melt CO₂ may be transferred into the bubbles, acting as a hidden CO₂ reservoir (Moore et al., 2015; Venugopal et al., 2020). The CO₂ content of bubbles should thus be analyzed to reconstruct entrapment melt CO₂ content (Lowenstern, 2015; Canatelli et al., 2016). In our study, we exclusively analyzed bubble-free MIs, following careful selection as recommended (Cannatelli et al., 2016; Rose-Koga et al., 2021), which rules out any significant CO₂ exsolution. If some melt inclusions with an undetected bubble were nevertheless analyzed, then these would correspond to MI compositions with low CO₂ – variably high H₂O content. Given the large number of inclusions studied, as well as the range of elements (major, trace and volatile) analyzed together support the main message brought by this study. In some cases, very high CO₂ contents (> 3000 ppm) have been detected in our MIs. These could result from contamination, but we note that the ¹²C⁺ signal was stable during SIMS analysis, which is consistent with high intrinsic CO₂ contents rather than any surficial carbon-rich contamination. We therefore posit that MI of our sample set were entrapped over a significant pressure range and thus over a significant vertical column within the crust. Over this pressure range, significant CO₂ exsolution occurred during magma ascent and open-system degassing, thus producing MIs with variable H₂O and CO₂ content (Fig. 9, 10). Potential fluxing by CO₂-rich vapour in the plumbing system may derive from degassing of deep, primitive magmas (Spilliaert et al., 2006; Johnson et al., 2008; Blundy et al., 2010), or assimilation of crustal carbonates (Marianelli et al., 2005) or shallow degassing within the conduit (Rust et al., 2004). Fluxing of shallow magmas with deeply-derived fluids is consistent with vertically extensive, fluid-saturated magma mush systems, in which melt and fluid movement can become decoupled (e.g. Christopher et al., 2015).

Using the MI volatile contents and literature data, we now evaluate pressure / depth of magma pounding zones for each of the studied Lesser Antilles islands:

- Montserrat: MIs in Montserrat's eruptive products record pressures ranging between ~50 and 500 MPa, corresponding to depths of ≈ 1.5-13.5 km (Figs. 9a, 10a, 11), assuming a crustal density of 2660 kg.m⁻³ (Christeson et al., 2008). This inferred depth range is consistent with storage depths between 5 and 16 km inferred by Edmonds et al. (2016) on the basis of the H⁺ content of orthopyroxene phenocryst cores or Mann et al. (2013) from melt inclusions. Seismic tomography and
thermal modelling suggest a 13 km³ magma reservoir at depths of ~5-8 km (Paulatto et al., 2012), and
3D geodetic inversions propose a southeastward dipping vertically extended ellipsoidal pressure
source centered at 9.5 km depth below main sea level (Gottsmann et al., 2021). Our data, however,
indicate the importance of transient magma evolution in the shallow crust beneath Montserrat, as most
MIs record pressures < 100 MPa (< ~3 km).

- Guadeloupe: For Guadeloupe, MI CO₂-H₂O contents correspond to saturation pressures ranging from ~50 to 650 MPa (depths ranging from ~1.5 to 19.5 km) (Figs. 9b, 10b, 11). The majority of MIs indicate pressures between ~50 and 200 MPa (1.5-6 km), with one MI composition corresponding to a pressure of ~600 MPa (Fig. 10b). Melt inclusion compositions indicating pressures of ~400-650 MPa are described in the literature, suggesting that the magma plumbing system at higher pressure (Fig. 11). For magmas that fuelled Guadeloupe's 1530 AD eruption, which comprise an unusually high proportion (80%) of mafic components, Pichavant et al. (2018) have experimentally constrained pre-eruptive magma storage and partial crystallization at pressures of ~130 to <200 MPa at depths of ~5.5-8.5 km for H₂O-rich MIs (~5.0-5.5 wt% H₂O; XH₂O ~0.9) (Fig. 10a). Such H₂O-rich MI compositions are present in our sample set, but they are rare. Deep, partial crystallization of mafic magmas (mafic andesites), including H₂O- and CO₂-rich magmas is consistent with our data, while magmas with more evolved, dacitic compositions appear to be stored at shallower depths, albeit without any obvious gap in magma storage pressure, and thus in a continuous magma mush zone.

- Dominica: Dominica magmas erupted at the northern and central volcanic centers of the island have the most hydrated MIs of the whole arc – with up to 7.6 wt % H₂O (Fig. 5a, 9b, 10b, 11; Balcone-Boissard et al., 2018). If we consider all MIs related to the three ignimbritic eruptions on Dominica, the MIs appear to have been equilibrated between ~150 and 750 MPa, corresponding to equilibration depths between ~5 and ~27 km (Balcone-Boissard et al., 2018). Here, MIs from PPVC show the same large equilibration pressure range as the central and northern eruptive centers, with similar H₂O and CO₂ contents as the Plinian eruptions emitted in the central part of the island (d'Augustin et al., 2020) (Fig. 9b). For lava-dome products of the same southern area, Gurenko et al. (2005) detected lower H₂O contents of ~2 to 6 wt% in MIs. This correspond to an equilibration depth
of 5-6 km (~200 MPa). The lower H₂O content is compatible with the observed effusive eruptive style, yet could record shallower crustal magma storage or more significant H₂O loss during magma ascent and eruption. In combination, all MI data available for Dominica, appear to record transcrustal pressure/depths with maximum pressure/depth corresponding to the limit of the Moho under Dominica (depth of ~28 km) (Fig. 11; Melekhova et al., 2019), while only few MIs record high pressures of > 300 MPa (Fig. 10b; 11).

Martinique: Andesitic magmas erupted at Montagne Pelée, however, have been inferred to have partially crystallized at deeper levels, i.e. at ≥300-400 MPa with melt H₂O contents between ~ 2.6 and 8.3 wt% (Pichavant et al., 2002). Such equilibration pressures are also recorded in our MI compositional data, mostly indicating equilibration pressures of 250-400 MPa, with few MIs recording pressure of up to 650 MPa (Fig. 9c, 10c, 11). In the southern part of the arc, MIs in the dacites from Martinique suggest storage depths between ~050 and 200 MPa (1.5 and 6 km depth). The lower MI re-equilibration pressures of ~50-150 MPa, which are common, could record re-equilibration during magma ascent. The higher pressures are in line with the conclusions of Martel et al (1998), who constrained pre-eruptive storage pressures for dacites erupted at Montagne Pelée to ~200±50 MPa.

St. Lucia: St. Lucia MIs, for which only few data exist, record equilibration pressures of ~200 to 50 MPa, compatible with the shallow magma storage inferred by Bezard et al. (2017).

St. Vincent: For St. Vincent, the MI entrapment pressures of phenocrysts of andesitic magmas ranges from ~50 to 450 MPa (depths of ~1.5 -10.5 km), with only one MI indicating a higher pressure of ~660 MPa (Fig. 9c, 10c, 11). Melt inclusions in phenocrysts of basaltic magmas erupted at St. Vincent, however, indicate high equilibration pressures between 1300-1450 MPa (Bouvier et al., 2008). Phase equilibrium experiments suggest polybaric magma evolution with storage and differentiation at >300 to >1000 MPa, including andesitic magmas (Pichavant & Macdonald, 2007; Melekhova et al., 2015).

The equilibration pressures of MIs in our sample set are thus overall lower than magma storage pressures that have been experimentally inferred, but may record continued polybaric evolution in the mid to upper crust, for which detailed experimental studies are lacking. Strict comparison with other
volcanic systems is not always possible on the basis of both H₂O and CO₂ measured concentrations, as often only based on H₂O content. Only in the northern part of the arc, dacitic to rhyolitic MIs from St Kitts record elevated magmatic H₂O contents of up to 8.5 wt % H₂O, for CO₂ content up to 1000 ppm (Melekhova et al., 2017). The barometry based on MI provides equilibration pressures between 50 to 400 MPa, equivalent to a crustal depth of <15 km. The high CO₂ content reported on few MIs and also in some matrix glasses testify to potential CO₂ flushing.

Correlating our MI compositional data with seismic data along the Lesser Antilles arc (Fig. 11) highlights the lateral complexity of crustal structure (Schaphorst et al. 2018; Melekhova et al., 2019) and magma system architecture. We propose that the discontinuity between the upper and the middle crust is a major magma ponding zone beneath most of the islands. All the islands show a well-developed transcrustal magmatic system, mainly in the upper and middle crust. These results may even be extended to the North to St. Kitts (Melekhova et al., 2017) and St. Eustatius (Cooper et al., 2019) and to the South to Grenada and Kick'em Jenny (Camejo-Harry et al., 2018), generalising the concept of the transcrustal magmatic system where magmatic processes occur along the whole Lesser Antilles arc.

In addition to H₂O-CO₂ solubility pressures, H₂O-Cl MI compositions provide an additional record of magmatic degassing (Fig. 12), especially when examining volatile-rich systems, as we do here (Webster, 1997). Pressure domains calculated on the basis of MI H₂O-Cl contents are in all cases in accordance with those estimated on the basis of CO₂-H₂O (Fig. 12).

## MIs as recorders of degassing

Volatile behavior is primarily controlled by degassing processes during magma ascent, owing to the strong dependence of volatile solubility on pressure (Goranson, 1931; Baker and Aletti, 2012 for a review). Equilibrium degassing is commonly assumed for most mafic magmas, because relatively high diffusivities of volatiles (owing to high temperatures) and low viscosity promote vapor-melt equilibrium during degassing, contrary to degassing of silicic magmas that have lower volatile solubilities and temperatures and higher viscosities. Degassing models predict that an ascending
magma will show a steep decline in the CO₂/H₂O ratio, owing to the low solubility of CO₂, until reaching shallow depths, where more significant H₂O degassing begins (Newman and Lowenstern, 2002; Liu et al., 2005; Papale et al., 2006; Duan et al., 2014). From high CO₂ – high H₂O MI compositions, which likely represent the least degassed entrapped melts, closed- or open-system degassing paths may be identified (Fig. 9). For each eruption, some MIs describe likely closed-system degassing paths, where the vapor phase produced is more and more H₂O-rich in high-silica melt (Fig. 9). Decompression-driven crystallization leading to degassing produces H₂O-rich MIs at the lowest pressures reached for each studied volcanic eruption (Fig. 10).

In addition, we can constrain volatile phase salinity using experimental data (Webster et al., 1997, 2004). Montserrat MIs, most of the 1530AD MIs of Guadeloupe, those of PPVC in Dominica, and the St. Vincent MIs indicate that NaCl-rich aqueous fluids were present, characterized by salinities of ~15 and up to ~50 wt%. MIs of the Pintade eruption of Guadeloupe, as well as the majority of MIs from Martinique, in contrast, are characterized by relatively NaCl-poor fluids, with salinities between ~1 and 15 wt%. Some MIs from Monts Caraïbes (Guadeloupe), Martinique and St. Vincent, in addition to all MIs from St. Lucia, are characterized by the lowest NaCl contents (<10 wt%; Fig. 12).

## Reservoir processes – fractional crystallization

755

*Effects of plagioclase crystallization:* Plagioclase strongly fractionates Sr (Moyen, 2009), thus significantly depleting evolving magmas in Sr and thus deceasing Sr in trapped MIs with increasingly evolved compositions (Fig. 7c) as shown for the ignimbritic eruptions of Dominica (Balcone-Boissard et al., 2018). Melt inclusions from St Lucia, Dominica and Montserrat have the most Sr-depleted compositions, indicating the most significant fractionation of plagioclase, followed by those of Guadeloupe, St. Vincent and then those of Martinique which have experienced less plagioclase fractionation (Fig. 7c). The different degrees of plagioclase fractionation are also evident in variably high, positive Sr anomalies (Fig. 6).

764

765
766 *Amphibole crystallization constraints*: An estimation of minimum magma storage pressures can be
767 obtained from the stability of amphibole (Barclay et al., 1998; Halama et al., 2006; Pichavant et al.,
768 2018). The majority of the Lesser Antilles eruptive products, however, do not contain amphibole
769 phenocrysts. Yet amphibole is an abundant constituent of cumulates of the Lesser Antilles arc
770 (Cooper et al., 2016). Whole-rock and MI fractionation trends show evidence for significant
771 amphibole fractionation within arc crust (Davidson et al., 2007). The degree of amphibole
772 fractionation is in some cases a criterion for identification of relative eruption deposits, e.g. as in the
773 case of various ignimbritic eruption products of Dominica (Boudon et al., 2017). Given that
774 amphiboles are absent in the emitted magmas most MIs were likely entrapped exclusively outside the
775 amphibole stability field. To track amphibole fractionation, it is interesting to look at the evolution of
776 Dy/Yb as a function of SiO₂ or La (Fig. 8d; cf. Davidson et al., 2007); indeed, this ratio is lowered by
777 the crystallization of amphibole. The Dy/Yb ratios decrease from MIs of St. Vincent, Guadeloupe,
778 Martinique, Montserrat and Dominica, to those of St. Lucia (Fig. 8d). Variations in bulk-rock Dy/Yb
779 may owe to mantle source variation and/or degree of partial melting, but the general decrease in
780 Dy/Yb from low-SiO₂ to high-SiO₂ Lesser Antilles magmas records fractionation of amphibole
781 (Davidson et al. 2013) at crustal or upper mantle level (Pichavant et al. 2002; Melekhova et al. 2015).

782

783 *MI trace-element contents as pressure probes?*

784

785 Above, we have used MI volatile contents and geophysical constraints to interpret the laterally
786 variable crustal and magma plumbing system structures, which is a commonly taken approach. Here,
787 we test if differentiated MI compositions and different geochemical proxies (La/Yb, Sr/Yb, Li/Y) can
788 be used to derive constraints of crustal thickness for the Lesser Antilles arc (Fig. 13a).

789

790 Ratios such as Sr/Y and La/Yb of magmas/melts are related to pressure due to the different affinity of
791 these trace elements in garnet (± amphibole) and plagioclase (Moyen, 2009; Davidson et al., 2007).
792 Plagioclase is stable at low pressure (400 MPa) whereas garnet is stable at high pressure. Partial
793 melting of garnet peridotite at high pressure or magmatic fractionation of garnet will produce melt
794 with high Sr/Y. At lower pressure, where garnet is absent, Y is incompatible while plagioclase
795 fractionates Sr, leading to melt with low Sr/Y (though higher than MORB signature; McDonough and
796 Sun, 1995). Similar partitioning relations control the La/Yb ratio. Using Sr/Y and La/Yb ratios of
797 magmas (bulk rocks) or melts (melt inclusions) have been proposed as crustal-thickness proxies.

798 Trace elements compositions (Sr, Y, La, and Yb) of melt inclusions may record details of pressure-
799 controlled evolution as minerals and melts evolve throughout lithospheric and crustal column,
800 possibly from the region of melt generation in the mantle wedge to the near surface ascending through
801 a more or less developed transcrustal magma system (Lieu and Stern, 2019). Crustal thickness thus
802 imparts a control on the geochemical signature of arc lavas, but this signature is modified during
803 trans-crustal magma evolution. Here by using anestimate of geochemical proxies based on a large
804 dataset, the complexity in their behaviours linked to fractional crystallization-assimilation processes
805 during magma ascent and storage in the crust is supposed to be averaged, allowing for broad patterns
806 of chemical changes with pressure to emerge as here.

807 Whole-rock geochemical ratios have recently been used as proxies for crust thickness (Turner and
808 Langmuir, 2015), including normalised La/Yb (La/Yb)n) or Sr/Y to determine the Moho's depth
809 (Profeta et al., 2015) or Li/Y to determine Li enrichment and crustal thickness (Chen et al., 2020).

810 The pioneering work of Chapman et al. (2015) showed that andesitic and dacitic whole-rock Sr/Y
811 vary regionally with crustal thickness in the western North American Cordilleran interior, reflecting
812 that the geochemistry of arc magmatism is sensitive to Moho's depth and variable magma flux. As
813 whole-rock compositions essentially average out petrological processes (source heterogeneities but
814 also magma mixing, fractional crystallization, assimilation), they have to be cautiously interpreted;
815 they nonetheless provide possible quantitative constraints on crustal thickness evolution in
816 subduction-related geodynamical context. We have investigated MI trace element compositions,
817 showing that their variation records entrapment and equilibration in transcrustal magma system (Fig.
818 11b). For St. Vincent, though the two geochemical proxies (La/Yb and Sr/Y) converge, they suggest a
819 shallower depth for the Moho than inferred by geophysical investigations. For Guadeloupe, the two
820 proxies partially converge. For Martinique, Dominica and Montserrat, there is significant discrepancy
821 between La/Yb and Sr/Y ratios, the latter systematically indicating shallower Moho depths (Fig. 13a).
These results likely reflect that we have considered highly differentiated magmas and MI compositions for Martinique, Dominica, Guadeloupe, and Montserrat, where significant Sr has been fractionated by plagioclase (Fig. 7c). The La/Yb and Sr/Y proxies therefore should not be used for such evolved melt compositions. Interestingly, the Sr/Y ratio of MIs has remained strikingly constant (13.7 ±0.5) in eruptive products that have been discharged over the last 60 kyrs of activity at Dominica (Fig. 13). This may illustrate the stability of the processes occurring at depth during magma differentiation through a long period of time. For Dominica, the mean La/Yb ratios indicate Moho depth estimates that are close to those as geophysically inferred (Melekhova et al., 2019).

Chen et al. (2020) proposed that Li/Y of primitive magmas show a subtle increase with increasing crustal thickness, interpreted as a consequence of garnet and/or amphibole influence in the mantle source, which sequester Y (which thus becomes less incompatible in the mantle assemblage). They further proposed that Li/Y ratio volcanic arcs magmas vary as a function of the depth at which differentiation occurs. A constant Li/Y ratio is noticed for arcs with crustal thicknesses less than ~25 km, whereas Li/Y ratios and SiO₂ (or Th used as a differentiation index, Fig. 13b) show a positive correlation for arcs with crustal thicknesses greater than ~30 km, which may be attributed to the appearance of amphibole and/or garnet as fractionating phases in thicker crust. The well-known effect of amphibole and garnet stability in decoupling Li and Y concentrations in melts is also corroborated by correlations between Dy/Yb and Li/Y in arc magmas. The Dy/Yb ratio largely decreased by amphibole crystallization. For MIs from Montserrat and the ignimbritic eruptions of Dominica, the Li/Y ratio is positively correlated with Th, thus suggesting high Moho depths (>25 km, as also determined by the La/Yb proxy; Fig. 13a, b); this is less evident for St Vincent, where more data are needed. For the other islands (Martinique, Guadeloupe) we observe that the Li/Y ratio is remarkably constant, which we interpret as a rather constant low pressure mantle source at depth (peridotite lacking garnet). For Dominica, the Li/Y ratios are variable for the different eruptions. They are either positively correlated with Th (ignimbritic eruptions) or constant showing a negative correlation with Th (plinian eruptions). This heterogeneity may be linked to variable storage depth of the emitted magmas: the ignimbritic eruptions are fed by magma stored deeply in the crust (~16 km; 400 MPa) (Solaro et al., 2019) contrary to the most recent Plinian eruptions (6-8 km; <200 MPa)
(d'Augustin et al., 2020). Ignimbritic eruption magmas are thus less prone to Li/Y modifications that complicate the interpretation of the ratio. For Guadeloupe the geochemical proxies (convergent La/Yb)n and Sr/Y (between 10-25) and constant Li/Y are in agreement with a shallower depth for the Moho contrary to the depth proposed by Melekhova et al. (2019). The petrological proxies indicate a more variable Moho's depth than combined geophysical data and cumulate petrological data (Fig. 13).

**Magma source components at depth: evidence from trace-element and halogen ratios**

The magmas studied here are, for the most part, highly differentiated and dacitic to rhyolitic in composition. As they are distant in composition from primary mantle-derived melts they thus provide us only with indirect information about their sources. Some trace-element and halogen ratios, however, will not be altered by differentiation as detailed below, and they can thus be used to characterise source compositions of the mantle wedge.

*Mantle wedge*

Along-arc variation in MIs, Y contents (Fig. 7b) and HREE contents (Fig. 7a) are consistent with the presence of various amounts of garnet in the sources of the Lesser Antilles magmas.

The U/Th ratios are spectacularly uniform for MIs from all eruptions on the northern islands from Montserrat to Martinique (Fig. 8b; S10). In comparison, there is a slight U enrichment in MIs from the eruption products of the southern islands of St. Lucia and St. Vincent. This indicates a change in the source characteristics. Uranium is more easily mobilized by fluids than Th where U solubility in aqueous fluids significantly increases with fluid salinity and oxygen fugacity, contrary to Th (Bali et al., 2011). This indicates a higher slab-derived fluid contribution to the magma source signatures in the southern part of the Lesser Antilles arc relatively to those of the northern part, probably by oxidized and moderately saline fluids. This conclusion is supported by the H₂O rich and Cl rich nature of MIs in St. Vincent products (1-40 %NaCl in fluids; fig. 12c), implying ample supply of aqueous fluids to the underlying part of the mantle wedge (Bouvier et al., 2010), as for St. Lucia fluids, with
moderate salinities (up to 30% NaCl; fig 12c). An alternative hypothesis is linked to the variable sediment input along the arc. As Uranium is notably enriched in sediments that contain organic carbon, which promote authigenic precipitation of reduced Uspecies (Plank, 2014). For instance, the black shales preserved in the ODP site 144 which show a strong U enrichment may be responsible of U/Th variation.

883 *Contributions of sediments and dehydration of altered oceanic crust to the magma sources*

884

Arc magmas have long been considered to originate from a combination of three components: a mid-ocean ridge basalt (MORB)-type peridotite mantle source, slab-derived fluid components produced by the dehydration of altered oceanic crust (AOC), and the melting of subducted sediments (Ulmer, 2001; Stern, 2002; Manning, 2004). It is possible to trace fluid contributions derived from AOC dehydration by considering fluid mobile to less fluid mobile or fluid immobile trace element ratios.

For example, Ba and Sr are preferentially incorporated in the aqueous fluid phase (mobile elements), whereas Th is only effectively transferred from the slab when sediments melt (immobile elements).

High Ba/Th ratios in magmas/melts are thus commonly interpreted to record high fluid source contributions from AOC dehydration (Fig. 8a).

In contrast, La and Sm are two relatively immobile elements that are not easily extracted from rocks by low-temperature aqueous fluids (Kessel et al., 2005). The La/Sm (as also La/Yb, see S10) is thus used as a proxy for the proportion of sediment-derived melt incorporated into the mantle wedge and derived magmas. For the Lesser Antilles arc (Fig. 8a), we can observe a large range of La/Sm ratios for MIs from Martinique and Dominica (2-10) and narrower ranges for MIs from Montserrat (5-9 ppm), suggesting highly variable yet low to high sediment melt contributions to the magmas. The only data point for St. Lucia has a high La/Sm ratio (8.5), which also points to high sediment melt contributions. Melt inclusions from the eruption products of Guadeloupe and St. Vincent show very limited variation and low La/Sm ratios of < 4 (Fig. 8a), indicating limited sediment melt contributions. These conclusions are consistent with previous studies (Labanieh et al., 2012).
Moreover, Labanieh et al. (2012) have highlighted a geographical gradient between sediment melt and slab-derived fluid contributions, illustrating high variability in magmas erupted in close spatial association: in Martinique, slab sediment melt components are incorporated predominantly under the western side of the island whereas slab dehydration components are mostly added beneath the eastern side, closer to the trench. The variable contribution of fluids to the mantle wedge may have impact on the well-developed accretionary system in the southern part of the Lesser Antilles, facilitating sediment subduction beneath the backstop and potentially into the mantle (Bangs et al., 2003).

Ba is considered as a fluid-mobile element contrary to Th and low Ba/Th ratios (but high La/Sm ratios) are thus commonly taken to reflect a higher contribution of sediment-derived melt respect to silicate-rich fluid. In Dominica, for MIs of the three ignimbritic eruptions, we find slightly lower Ba/Th ratios (40-50) than for more recent plinian eruptions or PPVC (50-60), thus indicating that slab dehydration components varied temporally and spatially. MIs from St. Vincent have overall the highest Ba/Th ratios (> 80), except for few MIs from Martinique with equally high values. When available, isotopes can help characterising the mantle melting conditions. For St. Vincent, Li-S stable isotope signature is consistent with fluid-rich mantle melting conditions (Bouvier et al., 2010).

Variation in Ba/Nb versus Th/Nb ratios further constrains different source contributions. Here two strong positive correlations exist (Fig. 8c): the first one is characteristic for MIs from Martinique, Guadeloupe and St. Vincent with low Ba/Nb and low Th/Nb ratios, the second one corresponds to higher ratios characteristic for Montserrat and Dominica's MIs. Interestingly, this second correlation including Dominica is the same as the one already described for another eruption from PPVC, the Cabrits (Gurenko et al., 2005). The first correlation is difficult to explain only by mixing of magma with a component having both high Th/Nb and Ba/Nb ratios. The scenario involving transfer by a fluid phase is problematic because Ba and Th have a very different mobility and correlations between Ba/Nb and Th/Nb would not be expected. The alternative to explain the simultaneous increase of the two ratios is a fractional crystallization where Nb behaves as a neutral or compatible element and where Ba and Th are similarly incompatible (Gurenko et al., 2005). The second correlation is more likely controlled by AOC fluids that leads to an increase in the Ba/Nb ratio.
932 *Halogen signature*

933 Recent improvements in the analytical characterization for F, Cl and Br offer new opportunities to
934 extend the use of halogen ratios (Cl/F and Cl/Br; Fig. 14) as specific tracers of the origin of magmas,
935 magma storage conditions or eruption dynamic (Balcone-Boissard et al., 2010, Cadoux et al., 2017).

936 Nevertheless during magma storage at low pressure (200 MPa), depending on temperature and
937 composition of the silicate melt, the phase stability of the (H₂O, CO₂, S, F, Cl, Br) system, though not
938 entirely resolved yet, indicates immiscibility domains (Driesner and Heinrich, 2017; Botcharnikov et
939 al., 2015). In case of a silicate melt in equilibrium with a H₂O-rich vapour phase, halogen behave as
940 incompatible element during magma differentiation. But in case of storage conditions of the magma
941 within the immiscibility domain, the silicate melt is in equilibrium with a two-phase fluid, composed
942 of a H₂O-rich vapour and a Cl-rich brine. Consequently, fixed concentrations of H₂O and Cl are
943 expected: this Cl buffer effect may be responsible for F, Cl and Br fractionation within magma
944 reservoir. Recent work shows fundamentally important solubility relationships involving H₂O, S, and
945 Cl: S reduces Cl solubility, which in turn reduces H₂O solubility in melts (Webster and Botcharnikov
946 et al., 2011). For the analyzed MIs, low S contents were measured (< 200 ppm), excepted for
947 Guadeloupe (up to 600 ppm) and Dominica (up to 300 ppm) which is consistent with the increase of S
948 partition coefficient in favour of the fluid phase with increasing silica content of the melt. In addition,
949 no S-bearing minerals were identified, potentially scavenging S.

950 For Montserrat, both Cl/F and Cl/Br ratios show a linear relationship (Fig. 14, S9) running
951 through the origin. The Cl/F ratio of 13 is roughly similar to the scatter ratio estimated based on
952 matrix glass by calculation by Villemant et al. (2008). This ratio is the highest among all studied
953 islands here. The Cl/Br ratio of ~500 is higher (Cl/Br~300) than those estimated by Villemant et al.
954 (2008). The discrepancies may come from the analytical uncertainty on halogen measurements on
955 whole rocks and then calculating melt concentrations using estimates of matrix versus phenocryst
956 abundances. The Cl/Br ratio remains constant, which attests to the fact that the products studied the
957 two eruptions of Montserrat come from a single source.

958
The lowest Cl/F ratio is attributed to MIs from St. Lucia (R=1.4, Fig. 14c); but it has to be confirmed by complementary measurements. The other islands are assigned more intermediate ratios: all eruptions of Dominica and Martinique share the same ratio, though F and Cl do not encompass a large compositional range (Fig. 14b, c). St. Vincent display the same Cl/F ratio, describing a larger domain of composition (Fig. 14c). For Guadeloupe, data are more scattered. For the 1530 AD and Pintade eruptions it is possible to infer changing behaviour for F and Cl. First, both F and Cl are incompatible before reaching H₂O saturation. Once saturation is reached, the Cl concentration drops down to a buffer value of ~1200 ppm (Fig. 14a).

The Cl/Br ratio is well defined for Montserrat and Guadeloupe, being close to seawater ratio (Fig. 14d). St. Vincent share the same Cl/Br ratio as Montserrat and Guadeloupe but with large Br content (Fig. 14f). All eruptions from Martinique share the same Cl/Br ratio (Fig. 14f). For Dominica, the Cl behaviour is complex relative to Br. There is a Cl/Br ratio shared by PPVC and some recent Plinian eruptions, but there is like a Cl buffering effect (~2500 ppm) for high Br content (>10 ppm)(Fig. 14e). This could possibly be the case for Martinique, with a lower Cl buffer value (~1280 ppm) (supplementary information S5). This buffer effect may possibly reflect a magma in equilibrium with a brine phase (rich in Cl) and a H₂O-rich vapor phase, as for Cl in Guadeloupe. All these ratios thus vary from one island to another, but are similar between eruptions for one volcanic center, indicating that halogen fractionation occurred by fluid transfer or by heterogeneities of mantle origin inherited from the initial geochemical fingerprint of the mantle wedge. The wide range of the Br/Cl ratio may be related to the variable assimilation rate of fluids derived from seawater. The northernmost island (Montserrat) has the highest halogen ratios but otherwise we do not observe any systematic along arc zoning.

## CONCLUSIONS

Major, trace and volatile elements (H₂O, S, F, Cl, Br) of MIs are valuable tools recording chemical variations of magmas and their mantle source regions in subduction zones and they may be exploited as geobarometer to track the ascent of magmas, especially important for the study of active volcanic
fields. Melt inclusion compositions of representative explosive eruptions involving mostly differentiated magmas along the Lesser Antilles arc were characterized for major and trace elements and volatiles. They are used to estimate pre-eruptive melt composition and elucidate their origin in different segments of the arc. Geochemical systematics of differentiated melts from the Lesser Antilles arc suggest that a large diversity of crustal (from subducting plate and overriding plates) and mantle (incoming plate and wedge) components are involved in the origin of geochemical zoning along arc. Large heterogeneity of MIs from representative whole-rock samples implies that sources of magmas are highly heterogeneous on the small scale. In addition, thanks to their volatile content, MIs provide possible constraints on the architecture of the plumbing system feeding the different volcanoes, illuminating the fact that a transcrustal magma plumbing system is systematically present, more of less deep-rooting in the crust.

- All the Lesser Antilles volcanic islands have a transcrustal magmatic system beneath, with a main magma ponding zone at the boundary between the upper and the middle crust.

- The highest melt volatile contents occur in the center of the arc, where the convergence is the least oblique and the magma productivity is the highest

- Variable amount of garnet is present in the mantle source along the arc, as highlighted by variable Dy/Yb ratio along the arc prior to the entrapment of the MIs

- Highly variable geographical contribution of sediment-melt and slab-derived fluids at the scale not only of the arc but also between individual eruptions on the same island.

- Wide range of Cl/F ratio, but the linear correlation indicates common magma sources. A wide range of Cl/Br ratios indicate variable assimilation degree of fluids derived from seawater. In some cases, Cl buffering effect are observed indicating brine saturation.

- La/Yb and Li/Yratios of evolved MI compositions are valuable proxies for crustal thickness, more than Sr/Y. They indicate a more variable petrological Moho depth beneath the Lesser Antilles arc compared to geophysical data, but the proxies have to be used with caution for differentiated magmas.
