Melt Inclusions in Izu Arc Lavas: Examining Slab-Derived Contributions to Intra-Oceanic Arc Magmas and the Role of Volatiles in the Subduction Factory

这项研究将通过日本、美国和欧洲的合作，利用岩相学、电子探针、离子探针和激光烧蚀电感耦合等离子体质谱技术，分析伊豆弧熔体包裹体和熔岩中的常量、痕量和挥发性元素(H2O、CO2、S、氯、F)和B、H同位素组成。熔体包裹体将提供原始伊豆弧熔体的主要、微量和挥发性元素含量以及硼和氢同位素组成的主要制约因素，这些数据将测试和制约该地区和其他地区俯冲的地球化学、岩石学、地球物理和热模型。

Via a Japanese, American, and European collaboration, this study will analyze major, trace and volatile elements (H2O, CO2, S, Cl, F) and B and H isotopic composition in melt inclusions and lavas from the Izu arc using petrographic, electron microprobe, ion microprobe and laser-ablation ICP-MS techniques. Melt inclusions will provide primary constraints on the major, trace and volatile element contents and boron and hydrogen isotope compositions of primitive Izu arc melts, and this data will test and constrain geochemical, petrological, geophysical and thermal models for subduction in this region, one of the MARGINS program selected study areas, and elsewhere.
