Determining the Pyroxene Mineralogies of Vestoids [PDF]
The Planetary Science Journal, 2023 Bulk pyroxene compositions were calculated for a number of V-type asteroid spectra using formulae derived by Burbine et al. These formulae were derived by analyzing HED (howardite, eucrite, and diogenite) meteorites and calculate bulk Fs (mol%) and Wo ...

Earth and Space Science, 2023 Although pyroxene has been detected remotely across the Solar System, limited information is available from infrared remote sensing about the Mg‐Fe composition of pyroxene, and distinguishing between augite (20 < CaSiO3 < 45) and diopside‐hedenbergite ...

The effect of metastable pyroxene on the slab dynamics [PDF]
Geophysical Research Letters, 2014 Seismic studies show that some subducting slabs penetrate straight into the lower mantle, whereas others seem to flatten near the base of the mantle transition zone.

An experimental study of pyroxene crystallization during rapid cooling in a thermal gradient: application to komatiites [PDF]
Solid Earth, 2014 To investigate the crystallization of pyroxene in spinifex-textured komatiites, we undertook a series of experiments in which compositions in the CaO-MgO-Al2O3-SiO2 CMAS system were cooled rapidly in a thermal gradient.

Quantifying the effect of pyroxene on deformation of peridotite in a natural shear zone
Journal of Geophysical Research: Solid Earth, 2015 The influence of pyroxene on upper mantle viscosity remains unclear but may occur either through its difference in strength relative to olivine or through its effect on olivine microstructure.

Mineralogical Journal, 1988 La Sous-Commission Pyroxènes créée par la Commission Nouveaux Minéraux et Noms de Minéraux (C.N.M.M.N.) de l'Association Minéralogique Internationale (I.M.A.) présente son rapport final sur la nomenclature des pyroxènes. Les recommandations de la Sous-Commission proposées dans ce rapport ont été officiellement acceptées par la Commission.

Phlogopite and associated minerals from Permian minettes in Devon, South England [PDF]
Bulletin of the Geological Society of Finland, 1985 Electron-microprobe analyses were made of mica, clinopyroxene, alkali feldspar, Fe‒Ti oxides and apatite in Permian minettes from Hannaborough Quarry, Killerton Park and Loxbeare Farm, south Devon, England.
