Langmuir 9302933 This project offers a different twist to the ongoing saga of mid-oceanic ridges. The P.I.s will analyze a selcted set of MORB glasses away from and close to hot spots for their water contents by infrared spectroscopy. They will determine Cl by electron probe at LDGO. The purpose is to evaluate how water relates to other geochemical pararneters and what role it plays in melt generation at MOR.

这个项目为正在进行的中大洋脊的传奇提供了一个不同的转折。P.I.s将通过红外光谱分析一组精选的MORB玻璃，以确定其远离热点和靠近热点的水分含量。他们将用电子探针在LDGO上测定Cl。目的是评价水与其他地球化学参数的关系，以及它在MOR熔体生成中所起的作用。
