Resonant Elasticity Measurements of Very Small Specimens: Applications to the Temperature Dependencies of Elasticity of High Pressure Phases

isak和Anderson pi建议使用共振超声光谱（RUS）来研究一组在高压下合成的具有重要地球物理意义的矿物的高温弹性。测量将需要进一步发展，使RUS技术适用于小样本的高温研究。硅酸盐钙钛矿或-尖晶石的单晶将在室温和高温下进行测量，赤铁矿和菱镁矿的高温特性也将完成，因为它们很容易获得更大的样品。研究结果将用于确定地幔的组成。＊＊＊

9614654 Isaak and Anderson The PIs propose to use Resonant Ultrasonic Spectroscopy (RUS) to study the high temperature elasticity of a suite of geophysically important minerals synthesized at high pressure. The measurments will require further development to adapt the RUS technique for high temperature studies on small samples. Measurements of single-crysals of silicate perovskite or beta-spinel will be made at room and high temperature, and the high temperature properties of hematite and magnesiowustite, for which larger samples are readily attained, will also be completed. The results will be used to constrain the composition of the earth's mantle. ***
