Recent Progress and Perspective of Experimental Mineral Physics: 2. Elasticity and Sound Velocity

Elasticity and sound velocity are critical physical properties of minerals. Comparing the experimental sound velocity of minerals with seismic observed velocity profiles provide crucial means to constrain the composition of the Earth's deep interior, understand the formation mechanisms of the Earth's layered structure, and decipher the lateral composition variation. In the past twenty years, significant progress has been achieved in the elasticity and sound velocity measurements with the development of various high?pressure experimental techniques, including large?volume press, diamond anvil cells, synchrotron X?ray facility, laser heating, etc. Here, we review the experimental progress in the elasticity and sound velocity measurements made in the past twenty years and discuss the future research topics and challenges.
