Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

Mineral properties hold dominion over planetary behavior as their physical and thermal
properties control mantle circulation, plate tectonics, melting behavior, and crustal …

Basalt is the most abundant rock on Earth. It forms the ocean ridges, slides off onto the
ocean fioor, and eventually dives back down. Basalt is the lava which pours out of Kilauea in …

The main source of carbon entering the deep Earth is through subduction of carbonates,
including CaMg (CO3) 2-dolomite. We examine the high-pressure structure and stability of …

The crystal chemistry of high-pressure (HP) silicates has been reviewed with special
emphasis on their structural topology and Si coordination. The HP silicates are subdivided …

Constraining Earth's bulk composition is fundamental to understanding our planet's
formation and evolution. While the lower mantle accounts for a majority of the bulk silicate …

SiO2 is one of the most fundamental constituents in planetary bodies, being an essential
building block of major mineral phases in the crust and mantle of terrestrial planets (1–10 …

Non-ideality in mineral solid solutions affects their elastic and thermodynamic properties,
their thermobaric stability, and the equilibrium phase relations in multiphase assemblages …

On compression of α-cristobalite SiO2 to pressures above approximately 12 GPa, a new
polymorph known as cristobalite XI forms. The existence of cristobalite XI has been known …

The last decade has seen the publication of a number of new and highly pertinent studies on
the composition of the Earth's lower mantle, leading to a better understanding of the Deep …
