Compositional Effects and Simultaneous P-T Effects on the Elasticity of Pyrope-Almandine-Grossular Garnet Solid Solution Series

9418727陈在压力~500Mpa，温度1000K，即高于石榴石的德拜温度的条件下，实验研究了组成效应和压力与温度同时作用对镁铝榴石-镁铝榴石-粗晶系列溶液弹性的影响。石榴石被认为是上地幔中最丰富的矿物之一。测量将使用最近开发的相干吉赫兹超声(CGU)干涉仪。将测量P波和S波的旅行时间。***

9418727 Chen The compositional effect and the simultaneous pressure and temperature effects on the elasticity of pyrope-almandine-grossular solution series will be studied experimentally, at pressures to ~500 Mpa and temperatures to 1000K, i.e. to above the Debye temperature of garnet. Garnets are considered to be among the most abundant minerals in the upper mantle. Measurements will made by using the Coherent Gigahertz Ultrasonic (CGU) interferometer recently developed. Both P- and S-wave travel times will be measured. ***
