Collaborative Research: Experimental Determination of Trace Element Distributions between Melts and Mantle Phases at P, T and X Relevant to MORB Genesis

9633778隆重标题：合作研究：实验测定P、T和X点熔体和地幔相之间与MORB成因有关的微量元素分布。大洋中脊玄武岩的形成始于地幔深处，随着地幔向上对流而不断发展。玄武岩的组成取决于地幔的组成、存在的矿物、熔融的温度和压力，以及熔融和熔体在地幔中移动的速度。玄武岩中的微量元素可以用来解释许多关于熔融的事情，但解释要求我们知道地幔矿物中的微量元素与熔融的地幔中的量的比率。这些比值(分布)是在高温高压下对地幔矿物进行的实验室实验中确定的。这个项目是为了扩大压力的范围，在这个范围内我们知道几个元素的分布。

9633778 Longhi Title: Collaborative research: experimental determination of trace element distributions between melts and mantle phases at P,T, and X relevant to MORB genesis. The generation of basalts at mid-ocean ridges starts deep in the mantle and progresses as the mantle convects upward. The composition of the basalts depends on the composition of the mantle, the minerals present, the temperatures and pressures of melting, and the speed of melting and movement the melt through the mantle. trace elements in the basalts can be used to explain much about the melting, but the explanations require that we know the ratio of the trace element in mantle minerals to the amount in the melted mantle. These ratios (distributions) are determined in laboratory experiments on mantle minerals at high temperature and pressure. This project is to extend the range of pressures at which we know the distributions of several elements.
