Ming 9527084 The PIs propose an experimental investigation of the thermal equation of state of perovskitite, the high-pressure perovskite-bearing asemblage of minerals thought to dominate the petrology of the lower mantle. The experiments will involve high-pressure, high-temperature determinations of P-V-T relations using synchrotron radiation, and the results should allow testing of models of distinct bulk composition for the earth's upper and lower mantle.

PI建议对钙钛矿的热状态方程进行实验研究，钙钛矿是一种高压含钙钛矿的矿物，被认为是下地幔岩石学的主导矿物。 这些实验将涉及利用同步辐射在高压和高温下测定P-V-T关系，其结果应能用来测试地球上地幔和下地幔不同的整体成分模型。
