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

通过日本，美国和欧洲的合作，这项研究将分析主要，微量和挥发性元素（H2O，CO2，S，Cl，F）和B和H同位素组成的熔融包裹体和熔岩从伊豆弧使用岩相学，电子探针，离子探针和激光烧蚀ICP-MS技术。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和硼和氢同位素组成的主要限制，这些数据将测试和约束地球化学，岩石学，地球物理和热模型俯冲在这个地区，MARGINS计划选择的研究领域之一，和其他地方。

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.
