Laboratory measurements of sound velocities of high-pressure minerals provide crucial information on the composition and…
Seismology records the presence of various heterogeneities throughout the lower mantle1,2, but the origins of these signals…
Laboratory experiments and seismology data have created a clear theoretical picture of the most abundant minerals that comprise…
Seismic studies indicate that beneath some regions the 520-kilometer seismic discontinuity in Earth's mantle splits into two…
140 GPa. The c/a ratio of the tetragonal structure is 1.018 at 100 GPa and increases on compression, as does the static enthalpy…
We investigate by first‐principles the structural behavior of CaSiO3 perovskite up to lower mantle pressures. We confirm that the…
SUBDUCTED slabs are less dense than the surrounding mantle near the base of the transition zone (660 km depth) because of the…
