An accurate assessment of the bulk chemical composition of Mars is fundamental to
understanding planetary accretion, differentiation, mantle evolution, the nature of the …

Abstract The Interior exploration using Seismic Investigations, Geodesy, and Heat Transport
(InSight) Mission will focus on Mars' interior structure and evolution. The basic structure of …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

Meteorites exposed to high pressures and temperatures during impact-induced shock often
contain minerals whose occurrence and stability normally confine them to the deeper …

Early in terrestrial planet evolution energetic impact, radiodecay, and core formation may
have created one or more whole or partial silicate mantle magma oceans. The time to …

The subduction of oceanic lithosphere into the Earth's deep interior is thought to drive
convection and create chemical heterogeneity in the mantle. The oceanic lithosphere as a …

We have determined the postspinel transformation boundary in Mg2SiO4 by combining
quench technique with in situ pressure measurements, using multiple internal pressure …

Phase relations in the natural pyrolitic mantle composition (KLB‐1) around 670‐km depth
have been determined at 1600–2200° C by high‐pressure experiments using multianvil …

The only martian rock samples on Earth are meteorites ejected from the surface of Mars by
asteroid impacts. The locations and geological contexts of the launch sites are currently …

Constraining the thermal and compositional state of the mantle is crucial for deciphering the
formation and evolution of Mars. Mineral physics predicts that Mars' deep mantle is …
