title: Reappraising the Early Palaeozoic tectonic framework of the Qinling orogenic belt: evidence from the magmatic records and evolution of interior tectonic units

description: The Qinling Orogenic Belt (QOB) is a composite orogenic belt located between the North China Craton (NCC) and the South China Block (SCB), and formed as a result of multiple episodes of collision and accretion. Although the tectonic history of the QOB has been extensively studied and reviewed, the evolution of the belt remains controversial. This contribution mainly reviews the geological, geochemical, and geochronological data of all the Early Palaeozoic intrusive and volcanic rocks of different genetic types in different tectonic units of the QOB and investigates their tectonic implications, together with the records of sediments, fossils and metamorphic rocks, to synthesize a new model for the Early Palaeozoic tectonic framework of the QOB. The QOB contains four discrete tectonic units (from north to south): the southern margin of the NCC, the North Qinling Terrain (NQT), the South Qinling Terrain (SQT), and the northern margin of the SCB. The Kuanping Ocean (represented by the Kuanping suture between the NQT and NCC) was a long-lived ocean rather than a backarc basin. Southward subduction of the Kuanping oceanic slab probably had begun before the Neoproterozoic and continued until the closure of the oceanic basin during the Early Palaeozoic. The subsequent retreat of the subducting slab caused the exhumation of deeply subducted arc volcanic rocks, forming high-pressure – ultrahigh-pressure metamorphic rocks at 500 My and the Erlangping backarc basin later. The closure of this basin and the subsequent collision between the NQT and NCC occurred at ca. 440 Ma. The Shangdan Ocean was a proto-Tethyan Ocean that had existed as early as the Neoproterozoic, the oceanic slab eventually underwent northward subduction towards the NQT at ca. 520 Ma, and this ocean closed by ca. 420 Ma. Marginal rifting and tectonic extension within the northern margin of the SCB formed the Mianlue oceanic basin during the Early Devonian. The complex interactions between the four discrete tectonic units within the QOB also led to the multiple-phase Early Palaeozoic metamorphic events, with the closure of the Kuanping, Erlangping, and Shangdan oceanic basins resulting in the HP – UHP and granulite- and amphibolite-facies metamorphism occurred at ca. 500, ca. 440, and 420 Ma, respectively.

title: Geochemistry of Neogene Nansatsu volcanic rocks in South Kyushu, Japan

description: We report the whole-rock major and trace element and Sr – Nd – Pb isotopic compositions of volcanic rocks from the Nansatsu area in South Kyushu. We analysed samples from the Oldest stage (middle Miocene), Older stage (late Miocene), and Middle stage (early Pliocene) Nansatsu volcanic rocks, which are andesite to dacite in composition, with an island-arc trace element signature. The compositional variabilities within the Older and the Middle stage rocks are relatively small compared to those in the Oldest stage and Quaternary volcanic rocks. Isotopic characteristics suggested that the Oldest stage volcanic rocks had magma sources similar to regional ilmenite-series granitoids of later ages (Outer Zone granitoids), which incorporated a substantial amount of graphite-bearing accretionary sediments (Shimanto Supergroup). The sources for the Older and Middle stage magmas were similar to those of primary Quaternary basalts in South Kyushu, indicating that Pliocene and Quaternary volcanic rocks in South Kyushu share a common mantle source, despite the change in the nature of volcanic activity from andesite-dominated to more variable volcanism of basalt to rhyolite.

title: Petrologic exploration criteria for magmatism-related uranium deposits: a review

description: Magmatic rocks host different types of uranium deposits that can range from magmatic/high-temperature hydrothermal systems to post-magmatic, low-temperature hydrothermal deposits. The uranium mineralization in the syn- or late-magmatic systems could be divided into three types. (1) Magmatic deposits related to differentiated peralkaline complexes that are typically rich in SiO<sub>2</sub> (&gt;72 wt%) and poor in (B: Fe+Mg+Ti)&lt;100 (in cation values). The Na/K ratio in these rocks is &gt; 1 and they have high contents of incompatible lithophile elements such as Nb, Ta, Zr, REE, Th and U. (2) Magmatic deposits related to strongly peraluminous magmas, derived from partial melting of crust. They are the result of a low degree partial melting of crustal arkosic (quartz-feldspathic) rocks with high SiO<sub>2</sub> (&gt;74 wt%), low B &lt; 40 and positive values for (A: Al-[Na+K + 2Ca]) (in cation values)), and are mostly accompanied by Li and F minerals. (3) Magmatic deposits related to the evolved hot peralkaline or metaluminous (A [A2] - to I- types) magma that assimilated fertile materials of the crust and endured a high rate of crystal fractionation. They mostly form high-temperature (vein-type and hybrid system) deposits. The rate of fluid in magma is important for the formation of this type of deposit. Therefore, the fertile magmas for this type of deposits typically have SiO<sub>2</sub> &gt;72 wt%, positive values of A, B &lt; 50 and K/Rb &lt; 150. They are possibly rich in Mo and F. Dry-hot alkaline felsic volcanic rocks are more suitable for post-magmatic low-temperature hydrothermal deposits. The altered intrusive rocks with about 200 Ma age and higher contents of refractory minerals, are suitable candidates for supporting the post-magmatic, low-temperature hydrothermal uranium mineralization.

title: Miocene lamprophyre and felsic volcanics in the outer zone of SW Japan: arc building through multiple sources in an active convergent margin

description: Subduction-related magmatism is a significant contributor to arc building and continental growth. In the active convergent margin of the SW Japan arc, voluminous volcanic rocks and mafic dykes formed through subduction and back-arc rifting during Miocene. In this study, we investigate a suite of felsic volcanic rocks (rhyolite and dacite) and lamprophyres from central Shikoku Island, which occur in the north-central part of the Chichibu belt and Sanbagawa belt in the Outer zone of the SW Japan arc. Whole-rock geochemistry results show that the rhyolite and dacite samples are peraluminous, belong to the high-K calc-alkaline series, show LREE and LILE enrichment, HREE and HFSE depletion that suggest arc volcanic affinity. The lamprophyre samples belong to alkali lamprophyre, show LREE and HFSE enrichments, and display OIB (oceanic island basalt)-like geochemical features. The <sup>206</sup>Pb/<sup>238</sup>U weighted mean ages of the zircons from the rhyolite and dacite samples range from 14.39 ± 0.21 Ma to 13.92 ± 0.30 Ma, whereas the lamprophyre shows <sup>206</sup>Pb/<sup>238</sup>U weighted mean age of 12.21 ± 0.35 Ma. Zircon Lu-Hf isotope data suggest that the rhyolite and dacite were derived from the remelting of the arc crustal rocks and that the lamprophyre was derived from depleted mantle sources and was contaminated by crustal materials. The felsic volcanic rocks (rhyolite and dacite) can be correlated to Miocene (15.5 Ma to 13.5 Ma) magmatism in the Outer Zone of the SW Japan arc. The formation of lamprophyre dykes in the SW Japan arc may be related to the subhorizontal mantle flows beneath the SW Japan arc associated with the opening of the Japan Sea back-arc basin or asthenosphere upwelling through the slab-tear of the Philippine Sea Plate beneath the SW Japan arc. Our study shows that the SW Japan Arc was built by multiple magmatism from diverse sources in an active convergent margin.

title: Cadomian tectonic evolution of Iran: records of an unusually hot and broad extensional convergent margin on the northern margin of Gondwana

description: The continental crust of Iran is dominated by abundant calc-alkaline and alkaline plutonic and volcanic rocks and by rifted basins filled with mostly terrigenous sedimentary rocks that formed at a Late Ediacaran to Cambrian extensional convergent plate margin along the northern margin of Gondwana. Here we present new zircon U–Pb age, geochemical, and isotopic data from plutonic (granite-granodiorite) and metamorphic (gneiss) rocks in the Kariznou region of NE Iran to provide insights into the nature of the Cadomian convergent margin of Iran. Geochemical data indicate calc-alkaline signatures, characterized by strong depletions in Nb, Ta, P, and Ti and arc-like trace element patterns. New zircon U–Pb ages show that calc-alkaline granitoids and granitic gneiss formed at ~564 to 537 Ma and 538 Ma, respectively. Bulk rock Sr-Nd isotopic data of calc-alkaline rocks have εNd(t) = –5.42 to −5.53 and −6.93 to −7.43 for granite and gneiss, respectively. The gneisses show stronger interaction with and/or re-melting of older continental crust than do granitic rocks. We interpret Kariznou magmatic rocks as forming in association with strong extension accompanied by crustal assimilation. Extension initiated ~570 Ma with the deposition of Late Ediacaran sediments, and magmatism began at 545–535 Ma, generating calc-alkaline magmas. The tectonomagmatic evolution of the Kariznou region encapsulates the prolonged transition of Cadomian Iran from a strongly extensional convergent margin, possibly as a result of oblique oceanic subduction and slab roll-back of the subducting Proto-Tethys oceanic lithosphere, culminating in the formation of an Early Palaeozoic passive margin on the northern side of Gondwana.
