Phase transformations in mantle mineralogies probably cause the transition zone seismic
discontinuities, nominally at 410, 520, and 660 km depth. Thermodynamic principles govern …

The geological and geophysical phenomena associated with water in the slab can be
grouped into three different categories: those related to 1) the storage of water in the oceanic …

We complete the development and description of a thermodynamic method for the
computation of phase equilibria and physical properties of multiphase mantle assemblages …

Phase relations of the olivine‐wadsleyite transition in the system (Mg, Fe) 2SiO4 have been
determined at 1600 and 1900 K using the quench method in a Kawai‐type high‐pressure …

High-pressure experiments (5–10 GPa, corresponding to approximately 150–300 km depth
in the mantle) have been conducted on a basalt+ calcite mixture in order to constrain the fate …

Partial melting of magnesite-bearing peridotites was studied at 6–10 GPa and 1300–1700°
C. Experiments were performed in a multianvil apparatus using natural mineral mixes as …

A variety of geophysical data indicates that long wavelength temperature variations of the
asthenosphere depart from the mean by±200° C, not the±20° C adopted by plume …

We derive exact expressions for the thermal expansivity, heat capacity and bulk modulus for
assemblages with arbitrarily large numbers of components and phases, including the …

We use a new method to construct an upper mantle model based on self‐consistent
computation of phase equilibria and physical properties. Computation of the isotropic elastic …

Cold, dense subducting lithosphere provides the primary force driving tectonic plates at
Earth's surface. The force available to drive the plates depends on a balance between the …
