Progress in seismic methodology and ambitious large‐scale seismic projects are enabling
high‐resolution imaging of the continental crust. The ability to constrain interpretations of …

Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

Brillouin spectroscopy is an optical technique that allows one to determine the directional
dependence of acoustic velocities in minerals and materials subject to a wide range of …

This paper reviews the progress of the technology of ultrasonic interferometry from the early
1950s to the present day. During this period of more than 60 years, sound wave velocity …

Geophysical remote-sensing methods, particularly seismology, provide an incredibly
detailed view of the structure and composition of Earth's mantle. The seismic velocity …

The single-crystal elastic moduli of minerals and related materials with cubic symmetry have
been collected and evaluated. The compiled data set covers measurements made over an …

In order to generate homogeneous high temperatures at high pressures, a ring-shaped
graphite heater has been developed to resistively heat diamond-anvil cell (DAC) samples …

By comparing the seismic wave velocity profile in the Earth with laboratory data of the sound
velocity of iron alloys, we can infer the chemical composition of materials in the Earth's core …

Si and C are cosmochemically abundant elements soluble in hcp Fe under pressure and
temperature and could therefore be present in the Earth's inner core. While recent ab initio …

Seismological studies give us a high-definition 3-D picture of the Earth's interior in terms of
seismic velocity and density. Near the surface, observations of these properties can be …
