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

题目：合作研究：与MORB成因相关的P、T、X熔体与地幔相微量元素分布的实验测定。洋中脊玄武岩的形成始于地幔深处，并随着地幔向上对流而发展。玄武岩的组成取决于地幔的组成、存在的矿物、熔化的温度和压力、熔化的速度以及熔体在地幔中的运动。玄武岩中的微量元素可以用来解释许多关于熔融的现象，但解释需要我们知道地幔矿物中微量元素与熔融地幔中微量元素的比例。这些比例（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我们所知道的几种元素分布的压力范围。

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.
