The interpretation of seismic data and computer modeling requires increased accuracy in relevant material properties in order to improve our knowledge of the structure and dynamics of the Earth's deep interior. To obtain such properties, a complementary method to classic shock compression experiments and theoretical calculations is the use of laser-heated diamond cells, which are now producing accurate data on phase diagrams, equations of state, and melting. Data on one of the most important… Expand

TLDR
The future of the study of the lowermost mantle will involve the linking of the ever-improving seismic observations with predictions of material properties from theoretical and experimental mineral physics in a quantitative fashion, including simulations of the dynamics of the deep Earth. Expand
Melting of iron determined by X-ray absorption spectroscopy to 100 GPa

Melting of Peridotite to 140 Gigapascals
TLDR
Melting phase relations and element partitioning data show that these liquids could host many incompatible elements at the base of the mantle, such that seismically anomalous zones near the boundary between the core and the mantle may result from isolated pockets of melt. Expand
High-temperature miscibility of iron and rock during terrestrial planet formation
Abstract The accretion of a terrestrial body and differentiation of its silicate/oxide mantle from iron core provide abundant energy for heating its interior to temperatures much higher than theExpand
A doubling of the post-perovskite phase boundary and structure of the Earth's lowermost mantle
TLDR
A pair of seismic discontinuities observed in some regions of D″ can be explained by the same phase transition as the result of a double-crossing of the phase boundary by the geotherm at two different depths. Expand

TLDR
The experimental observations, in conjunction with seismological data, suggest that the lowermost 200 to 300 kilometers of Earth's mantle, the D" layer, may be an extremely heterogeneous region as a result of chemical reactions between the silicate mantle and the liquid iron alloy ofEarth's core.
