- Harzburgite typically forms by the extraction of partial melts from the more pyroxene-rich peridotite called lherzolite.
- The upper mantle of Earth is composed mainly of olivine and pyroxene minerals. Pyroxene and feldspar are the major minerals in basalt, andesite, and gabbro rocks.
- It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene.
- These conditions are created by the high-temperature fractionation of highly magnesian olivine or pyroxene, which causes a relative iron-enrichment in the residual melt.
- This process occurs by hydration of ferromagnesian minerals, particularly hornblende, which may adsorb up to 5% H2O, and by conversion of pyroxene to hornblende during melting or fractionation at temperatures below the pyroxene stability field.
- The spectrum of this object indicates that it is an S-type asteroid with both low and high calcium forms of pyroxene on the surface, along with less than 20% olivine.
- The pyroxene-rich rocks, which result from the type of contact metamorphism known as pyroxene-hornfels facies, have siliceous sediment or basaltic protoliths, and are respectively metapelites and metabasites.
- Gabbroic pegmatites typically consist of exceptionally coarse interlocking pyroxene and plagioclase.
- He focused his research mainly the experimental study of pyroxene-bearing systems, such as acmite, Titanium-bearing pyroxene, and fassaite, in order to understand the genesis of nephelinitic magma.
- Metamorphic temperatures were determined based upon the measured oxygen fugacity, using the two-pyroxene and olivine-spinel geothermometry methods.
- Small grains of hornblende and pyroxene are also found where the pyroxene is associated with biotite.
- The seatbelt basalt is a highly-vesicular, olivine-normative, basalt with phenocrysts of zoned pyroxene and olivine within a matrix of pyroxene and plagioclase.
- Kushiroite is a rare mineral of the pyroxene group, with formula CaAlAlSiO6.
- El Negrillar has erupted basaltic andesite containing olivine, andesite containing either olivine-pyroxene, pyroxene or pyroxene-hornblende, and dacite.
- Eclogite facies is typically encountered around 80–100 km depth and is characterized by the presence of green omphacitic pyroxene and red pyrope garnet.
- The mineral composition is variable, but commonly contains mica and pyroxene while porphyroblasts of pyroxene, cordierite or andulusite also develop.
- Most of the mantle xenoliths at Kilbourne Hole are composed of lherzolite, a rock composed mostly of olivine and pyroxene.
- The pyroxene group consists of 21 mineral species. Pyroxenes have a general structure formula of XY(Si2O6), where X is an octahedral site, while Y can vary in coordination number from six to eight.
- Uralite is a particular hydrothermally altered pyroxenite; during autogenic hydrothermal circulation the primary mineralogy of pyroxene and plagioclase, etc.
- One example reaction is an exchange of Fe2+ and Mg2+ within garnet and clinopyroxene.
