Equipment for Elasticity Measurements of Earth Materials at High Pressures and Temperatures

该奖项提供部分（76%）资金用于购置设备（一个固态锗探测器和两个氩离子激光管），用于对地球地幔和地核材料进行高压实验。这项工作将由华盛顿卡内基研究所（CIW）的地球物理实验室进行，CIW承诺提供收购所需的剩余资金。该设备将被纳入用于研究弹性（导致地震速度）和重要矿物钙钛矿状态方程的实验系统中，钙钛矿是一种镁铁硅酸盐，被认为是地幔中的主要相。由此产生的测量结果将用于根据地球深部结构和动态过程的模型来解释地震数据。＊＊＊

9709572 Mao This award provides partial (76%) funding for the acquisition of equipment (a solid state germanium detector and two argon ion laser tubes) to be used in conjunction with high-pressure experiments on materials of the Earth's mantle and core. The work is to be carried out by the Geophysical Laboratory of the Carnegie Institution of Washington (CIW), and CIW is committed to providing the remaining funds necessary for the acquisition. The equipment will be incorporated in experimental systems used to investigate the elasticity (leading to seismic velocities) and the equations of state of the important mineral perovskite, a magnesium-iron silicate considered to be the dominant phase in the mantle. The resulting measurements will be used to interpret seismic data in terms of models of the structure and dynamic processes of the Earth's deep interior. ***
