该奖项将提供所需资金的一半， 傅里叶变换红外光谱仪的收购。 的 已承诺为此次收购提供额外资金 由位于圣克鲁斯的加州大学提供。 预计 利用这一工具进行的研究将提供基本的 地球化学和地球物理过程的一些限制。 这些包括但不限于：1）检查 高温下硅酸盐熔体的结构变化 压力，从而可能影响分化过程 （2）在地球早期发生的;（3）描述物种的形成。 挥发物（主要是水和二氧化碳）在两个混合 在中等压力下的挥发性流体相，以及在挥发性流体相中， 含有硅酸盐组合，与溶液 流体在高压和高温下的性质，以及 挥发物可能滞留在地球深处; 3）调查 矿物的结合性能对高压的响应， 这两个方面的影响， 矿物在极端条件下，并为机制， 矿物经历亚稳相变;和4）一种新的 用于潜在地表征热传导性的方法 高压下的不透明材料。

This award will provide for half the funds needed for the acquisition of a Fourier Transform Infrared Spectrometer. The additional funding required for this acquisition has been committed by the University of California at Santa Cruz. It is anticipated that studies utilizing this instrument will provide fundamental constraints on a number of geochemical and geophysical processes. These include, but are not limited to 1) examination of the structural changes taking place in silicate melts at high pressures, and thus potentially on differentiation processes occurring in the early Earth; 2) characterizing the speciation of volatiles (primarily water and carbon dioxide) within both mixed volatile-fluid phases at moderate pressures, and in volatile- bearing silicate assemblages, with relevance both for the solution properties of fluids at high pressure and temperature, and for possible retention of volatiles in the deep Earth; 3) investigating the response of bonding properties of minerals to high pressures, with implications both for the thermochemical properties of minerals under extreme conditions, and for the mechanisms by which minerals undergo metastable phase transitions; and 4) a novel method for potentially characterizing the thermal conductivity of opaque materials at high pressures.
