The most abundant mineral in Earth's interior gets a name [Also see Report by Tschauner et al.] The most abundant solid phase in Earth's interior, making up 38% of Earth's volume, is magnesium iron silicate (Mg,Fe)SiO3. This material is known to form a perovskite structure. However, no samples of the mineral can be obtained from Earth's lower mantle; without a well-characterized natural sample, it has not been possible to formally name the mineral. On page 1100 of this issue, Tschauner et al…

A density functional theory based thermodynamic approach is used to establish the range of stability of bridgmanite as well as possible termination structures of the (001), (010), (100) and (011) surfaces as a function of the chemical potential of oxygen and magnesium.

Discovery of bridgmanite, the most abundant mineral in Earth, in a shocked meteorite
The discovery of this important phase as a mineral in the Tenham L6 chondrite and approved by the International Mineralogical Association is reported, putting to rest a confusing nomenclature of this dense deep mantle silicate.
Ringwoodite, Natural (Mg,Fe)2SiO4 Spinel in the Tenham Meteorite
WE have observed numerous rounded purple isotropic grains up to 100 microns in diameter in thin sections of two stones from the Tenham meteorite shower1 (British Museum B.M.1935,792 and Australian
Hydrous mantle transition zone indicated by ringwoodite included within diamond
X-ray diffraction, Raman and infrared spectroscopic data are reported that provide the first evidence for the terrestrial occurrence of any higher-pressure polymorph of olivine: ringwoodite is included in a diamond from Juína, Brazil, providing direct evidence that, at least locally, the transition zone is hydrous.
Natural (Mg,Fe)SiO3-ilmenite and -perovskite in the Tenham meteorite.
The higher iron concentration in both phases compared with those experimentally reported may suggest their metastable transition from enstatite because of shock compression.
Minerals in the Deep Earth: A Message from the Asteroid Belt
Knowing what minerals form at different depths in the Earth9s mantle is crucial for fully understanding processes such as plate tectonics and volcanism. Since the 1930s it has been known that some of
Natural dissociation of olivine to (Mg,Fe)SiO3 perovskite and magnesiowüstite in a shocked Martian meteorite
Transmission electron microscopy observations reveal that microtexture of olivine dissociation products evolves from lamellar to equigranular with increasing temperature at the same pressure condition, in accord with the observations of synthetic samples recovered from high-pressure and high-temperature experiments.
Deep Earth and Recent Developments in Mineral Physics
Very few rocks on the Earth's surface come from below the crust. In fact, most of Earth's interior is unsampled, at least in the sense that we do not have rock samples from it. So how do we know what
Meteorites and the early solar system II
They range in size from microscopic particles to masses of many tons. The geologic diversity of asteroids and other rocky bodies of the solar system are displayed in the enormous variety of textures
Pressing on: The legacy of Percy W. Bridgman
Percy Bridgman invented mechanical devices that dramatically expanded the high-pressure range available for carrying out physics and chemistry experiments into an unprecedented regime of high densities, which revolutionized condensed matter research.
