中文摘要
该项目将确定同位素组成, 该项目将确定同位素组成, 稀有气体(氩、氦和氖)的浓度, 斑晶和玻璃中的挥发物(氢、碳等) Lau盆地、马里亚纳海槽、Lohihi海山的玄武岩, 马努斯盆地北斐济盆地等地区。 的结果 研究预计将回答几个重要问题, 弧后盆地玄武岩成因与地幔化学
英文摘要
The project will determine isotopic compositions and The project will determine isotopic compositions and concentrations of rare gases (Argon, Helium and Neon) and Volatiles (Hydrogen, Carbon, etc) in phenocrysts and glassy basalts from the Lau basin, Mariana Trough, Lohihi Seamount, Manus basin N. Fiji Basin and other areas. The results of this study are expected to answer several important questions about petrogenesis of basalt in backarc basins and mantle chemistry.
