title: I/Ca data from Lower–Middle Ordovician carbonate strata in Baltoscandia

description: This dataset documents a survey of iodine-to-calcium, I/(Ca+Mg), redox proxy data from Lower–Middle Ordovician carbonate strata at various localities in Baltoscandia. Samples derive from Grönhögen, Horns udde, Hällekis, Killeröd, Knivinge, Kårgärde, Lanna, Lyckhem, and Skärlöv in Sweden; Uuga cliff and Väo in Estonia; Lynna River in western Russia. The I/(Ca+Mg) analyses were done to explore spatiotemporal variability in marine shelf oxygen conditions across the Baltoscandian palaeoshelf during the Early through Middle Ordovician. Sample preparations and analyses were done following established I/(Ca+Mg) methods, using an Agilent 7500cs inductively coupled-plasma mass spectrometer. The I/(Ca+Mg) data indicate progressive oxygenation of the Baltoscandian palaeoshelf during the studied time interval.

title: Cation, anion, and isotope chemical data of fluids from Costa Rica outer forearc, forearc, and arc springs

description: Cation, anion (including halogens), stable isotope (O, H, Cl, Li, B), and 3He/4He geochemical data of fluids from Costa Rica outer forearc, forearc, and arc springs. Spring fluids are from cold and hot springs. Fluid chemistry reflects contributions from differing subducting slab sources, with some late modification (e.g., fluid-rock interaction, kinetic fractionation due to phase separation). Data can be used to evaluate volatile recycling through the forearc and potential changes in fluid source from the dehydrating subducting slab.

title: Evidence of phosphorous cycling in the slab-mantle interface from apatite in retrogressed eclogites

description: We studied apatite from retrogressed eclogites in a serpentine matrix from the North Motagua Mélange (Guatemala) to understand P behavior in the subduction interface. The retrogressed eclogites display eclogite-, blueschist-, and ep-amphibolite-facies assemblages at different modal abundances and have been linked to two rehydration events in the interface. Textural analyses, mineral assemblages, and inclusions indicate that apatite increases in size and crystallizes or overgrows from eclogite- to blueschist-epidote-amphibolite transition facies, while chemical dissolution at epidote-amphibolite-facies suggested by the record of highly altered appearance of apatite. In our samples, all apatite crystals are halogen-poor and relatively enriched in Sr, Y, and Pb. When normalized to chondrites, the eclogite and blueschist apatite change from depleted to enriched light rare earth elements (REE) patterns and also contain B, As, and Ba. In contrast, epidote-amphibolite apatite display depleted light and middle REE patterns and are enriched Cr, Mn, and U. Our data suggest fluid-rock interaction with two different fluids, an Al-, K-, and P-rich fluid that crystallized apatite, and the second was Na-, Si-, and Ca-rich that dissolved apatite, indicating that P in the subduction interface moves readily between fluid and solid phases, a behavior that it known to its cycle on Earth’s surface.

title: Large Nitrogen Cycle Perturbations During the Early Triassic Hyperthermal Interval

description: Ocean temperature, redox state, circulation, and nutrient levels regulate marine nitrogen (N) cycle, yet their impacts during greenhouse intervals remain poorly understood. Here, we examined the Smithian–Spathian hyperthermal event (~250.5 Ma) during the Early Triassic greenhouse using stable N isotopes (δ15NDCN) from two basins in South China. The Smithian hyperthermal interval exhibited low δ15NDCN (+1‰ – +3‰), indicating N deficiency and enhanced N2 fixation. Subsequent cooling across the Smithian–Spathian boundary led to discrete δ15NDCN changes, likely reflecting signals of partial NH4+ assimilation in anoxic and NH4+-enriched conditions. In the early Spathian with milder temperatures, biological N gradually changed to nitrate-dominated sources from partial denitrification, as indicated by increased δ15NDCN (up to +3‰ – +6‰). Eukaryotic algae thrived while prokaryotes declined during the Spathian, evidenced by elevated δ15NDCN and Δ13Ccarb-org (carbonate-organic carbon isotope difference). These findings highlight significant turnovers in N cycle in response to temperature changes in low-latitude South China.

title: Exhumed serpentinites and their tectonic significance in non-collisional orogens

description: We studied serpentinite samples from five river basins in a segment of the non-collisional Andean orogen in Ecuador (Cordillera Real). All samples are fully serpentinized with antigorite as the main polymorph, indicative of high-temperature serpentinization, while spinel is the only relic phase. Whole-rock rare earth element data suggest an abyssal setting for the protoliths. In-situ B isotope data on antigorite (delta 11B = -15.9‰ to +5.7‰) and chlorite (delta 11B = -6.3‰ to -3.6‰) favor serpentinization by crust-derived metamorphic fluids in a mantle wedge setting. Our data suggest four different mantle wedge-derived serpentinite slivers draining into the northern Cordillera Real stream network, likely associated with Triassic, Jurassic-Early Cretaceous, and potentially Late Cretaceous-Paleocene high-pressure low-temperature metamorphic sequences. We propose that serpentinites in non-collisional orogens are sourced from underplated slab slivers that undergo intense serpentinization by crust-derived metamorphic fluids in the mantle wedge prior to their exhumation during extensional phases.

title: Melt inclusion and matrix glass data from the 43 BCE eruption of Okmok Volcano

description: Here, we present major element and volatile concentrations for a suite of 19 olivine(Fo38-87)- and plagioclase(An38-86)-hosted melt inclusions and 23 matrix glasses from 4 bulk samples collected from the 43 BCE caldera-forming eruption of Okmok Volcano, Alaska (Okmok II). This eruption has recently been connected with a sulfur-rich layer in Greenland ice cores that contains tephra matching the geochemical composition of Okmok II eruptive products. Proxy evidence of climate cooling and historical observations of extreme climate also coincide with the timing of Okmok II, thus prompting further study of the volatiles released during the eruption. Melt inclusions, host crystals, and matrix glasses were singly polished and analyzed by Electron Microprobe, with select inclusions also measured by Secondary Ion Mass Spectrometry (SIMS), with the goal of producing a total petrologic S load for the Okmok II eruption. SIMS analysis was carried out with a Cs+ beam, and oxygen-normalized ratios were calibrated using DTM basaltic glass standards with all calibration lines being highly linear (r2&gt;0.98). For further description of melt inclusion populations and volatile content, refer to publication main text and supplementary information.

title: Titanium stable isotopic compositions of chondrites and ancient to modern terrestrial mantle-derived lavas

description: We report ultra-high precision 49Ti/47Ti ratios for chondrites, ancient terrestrial mantle-derived lavas ranging from 3.8 to 2.0 Ga and modern oceanic island basalts (OIBs). Our new Ti bulk silicate Earth (BSE) estimate based on chondrites is 0.052±0.006‰ heavier than the modern upper mantle sampled by normal-type mid-ocean ridge basalts (N-MORBs). The 49Ti/47Ti ratio of Earth’s upper mantle was chondritic before 3.5 Ga and evolved to a N-MORB-like composition between ~3.5-2.7 Ga. Modern OIBs record variable 49Ti/47Ti ratios ranging from chondritic to N-MORBs compositions.

title: Mineralogical controls on the Ti isotope composition of subduction zone magmas

description: We have determined the Ti isotope composition of well-characterized, subduction-related basalts, andesites and boninites. Samples from the Solomon Islands, the Troodos ophiolite in Cyprus, and Cape Vogel in Papua New Guinea show small but resolvable variations, that may be related to differences in their mantle sources. Our study highlights that the combination of diagnostic trace element patterns, and Ti isotope compositions in subduction-related igneous rocks can be a powerful tool to constrain petrogenetic processes and to discriminate between different crystallizing mineral phases.

title: Bulk rock major, trace element, and Sr-Nd-Pb isotope composition of Mascarene Island OIB

description: The Mascarene Islands in the western Indian Ocean, encompassing La Réunion, Mauritius, and Rodrigues, are the recent (&lt;10 Ma) surface expressions of the Réunion volcanic hotspot. Ocean island basalts (OIB) from these islands display a remarkably limited range in long-lived radiogenic isotopic compositions that generally overlap the convergence field of many global OIB trends in the mantle array. This dataset presents whole rock Sr-Nd-Pb isotope compositions together with major and trace element abundances for OIB samples from all three Mascarene Islands, which were collected during a field campaign in 2007. Major and select trace element abundances were obtained using X-ray fluorescence analysis (XRF), along with measurement of loss on ignition and ferrous Fe abundance by titration. Strontium isotope data was acquired using thermal ionization mass spectrometry (TIMS), whereas Nd and Pb isotope as well as other trace element compositions were measured by inductively coupled plasma mass spectrometry (ICP-MS). The purpose of this dataset is to characterize the persistence of Réunion plume-like and enriched signatures across the Mascarene Islands chain.
