The measurement of mineral elastic properties through experimental studies is crucial for seismic data interpretation and can aid in our understanding of the deformation processes that shape our Earth. Measurement of acoustic velocities, absolute pressure determination, and derivation of thermoelastic equations of state for various materials is traditionally done through experimental collection of ultrasonic interferometry measurements in conjunction with synchrotron X-radiation in a multi-anvil apparatus (Li et al., 2004). Lab-based elastic constants and velocity measurements are used by seismologists to interpret the Earth's interior, however, the constants describing the change in seismic velocity due to stress perturbation has yet to be measured at deep Earth conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
