U.S.-France Cooperative Research: Integrated Studies of Oceanic Spreading Centers of the Oman Ophiolite

小行星9313822 这个为期三年的奖项支持美国-法国地球化学和岩石学合作研究。 美国调查人员，伍兹霍尔海洋研究所的清水伸道和克莱门，美国地质调查局的奎克和G。 加州理工学院的瓦瑟堡将与法国蒙彼利埃大学的阿尔多菲·尼古拉斯和德尔菲娜·博世合作研究阿曼蛇绿岩。 蛇颈岩是海洋地壳的暴露部分，由火山和火成岩增生形成，在中部海洋扩张中心。 目的是对阿曼蛇绿岩中保存的地幔岩石中的地幔橄榄岩和熔体迁移进行综合的野外和实验室研究。该蛇绿岩因其出露和残留地幔厚度而特别适合。这项研究的结果将增进对洋中脊和洋壳形成所涉物理过程的了解。 美国和法国的研究小组将在阿曼北方进行广泛的采样，然后在美国进行数据分析和会议。研究人员涉及许多学科，包括构造地质学、岩石学、微量元素地球化学和同位素地球化学。 该项目利用了法国在阿曼蛇绿岩方面的重要专业知识，并提供了法国小组绘制的详细结构图。 ***

9313822 Shimizu This three-year award supports U.S.-France cooperative research in geochemistry and petrology. U.S. investigators, Nobumichi Shimizu and Peter Kelemen of Woods Hole Oceanographic Institution, J. Quick of the U.S. Geological Survey and G. Wasserburg of the California Institute of Technology, will collaborate on studies of the Oman ophiolite with French investigators, Aldophe Nicolas and Delphine Bosch of the University of Montpellier, II. Ophiolites are exposed sections of the ocean's crust formed by volcanic and igneous rock accretions at mid ocean spreading centers. The objective is to conduct integrated field and laboratory studies of mantle periodites and melt migration in mantle rocks as preserved in the Oman ophiolite. This ophiolite is especially suitable due to its exposure and thickness of its residual mantle. The results of the study will advance understanding of the physical processes involved in mid-ocean ridges and formation of oceanic crust. The U.S. and French groups will carry out extensive sampling in northern Oman followed by data analysis and meetings in the U.S. The investigators cover many disciplines including structural geology, petrology, trace element geochemistry, and isotope geochemistry. The project takes advantage of significant French expertise on the Oman ophiolite and provides access to detailed structural mapping developed by the French group. ***
