RIDGE Postdoctoral Fellowship Program: Chlorine Stable Isotopes in Mid-Ocean Ridge Basalt Glasses: Development of a New Tracer for Crustal Recycling

哈南（Hanan）是该项目的负责人，每两年为马根海姆博士后提供12个月的支持，以完善测量玄武岩中氯同位素的技术。利用该技术，Magenheim将确定海洋地壳同化对氯同位素的影响，并评估morb中氯同位素热点的贡献。这可能有助于确定被再循环进入地幔的地壳的数量。它还可以用来确定弧后火山活动中俯冲地壳的哪一部分返回到地表。这是一种新兴的技术，马根海姆在发展中发挥了重要作用，它有很大的潜力告诉我们主要的地质过程。这个项目是RIDGE计划（RIDGE跨学科全球实验）的一部分。＊＊＊

9504167 Hanan Hanan is the PI on this request for 12 months of support for each of two years for postdoctoral Magenheim to prefect the technique of measuring chlorine isotopes in basalts. With this technique Magenheim will determine the effects of assimilation of oceanic crust on chlorine isotopes and evaluate the contribution of hotspots in chlorine isotopes in MORBs. This may be useful in determining the amount of crust that has been recycled into the mantle. It could also be used to determine what part of the subducted crust is returned to the surface in back-arc volcanism. This is an emerging technique that Magenheim was instrumental in developing and which has great potential for telling us about major geological processes. This project is part of the RIDGE initiative (Ridge Interdisciplinary Global Experiment). ***
