为了检验关于伊豆弧下岩石形成过程的三个假设,PI将分析通过疏浚、ALVIN和ODP腿以及未来IFREE/JAMSTEC巡航收集的海底岩石。根据该合同,研究员将研究50-100个玄武岩的岩相学、矿物化学、主要和微量元素(XRF、ICPMS)以及Sr-Nd-Pb-Hf同位素,这些玄武岩大多来自伸展区域,但也来自火山前弧和后弧海山链。他们还将测量这些样本中适当的镁铁质子集以及来自伊豆岛弧外侧太平洋地壳ODP 1149站点的沉积物和玄武岩的高优先级子集的187 Os/ 188 Os比率和Re-Os浓度。
英文摘要
In order to test three hypotheses regarding petrogenetic processes below the Izu arc, the PIs will analyze submarine rocks collected by dredging, ALVIN and ODP legs, and from a future IFREE/JAMSTEC cruise. Under this award, the PIs will study the petrography, mineral chemistry, major and trace elements (XRF, ICPMS), and Sr-Nd-Pb-Hf isotopes of 50-100 basalts, mostly from the extensional region, but also from the volcanic front and rear arc seamount chains. They will also measure 187 Os/ 188 Os ratios and Re-Os concentrations for a suitably mafic subset of these samples, and for the high-priority subset of sediments and basalts from ODP Site 1149 in the Pacific ocean crust outboard of the Izu arc.
