中文摘要
为了检验关于伊豆弧下岩石成因过程的三个假说,PI将分析疏浚、阿尔文和ODP段以及未来IFREE/JAMSTEC巡航收集的海底岩石。根据这一奖项,PIS将研究50-100个玄武岩的岩石学、矿物化学、主要和微量元素(XRF、ICPMS)以及锶-钕-铅-氢同位素,这些玄武岩主要来自伸展区域,但也来自火山前缘和弧后海山链。他们还将测量这些样品中适当的镁铁质子集以及伊祖弧外侧太平洋地壳中ODP1149站点的高度优先的沉积物和玄武岩的187Os/188Os比值和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.
