The role of pyroxenite in basalt genesis: Melt‐PX, a melting

Although a variety of names are used to describe rocks falling under the general heading of "pyroxenite" (e.g., orthopyroxenite, websterite, bronzitite, eclogite), we use the term pyroxenite to refer to mafic and ultramafic pyroxene-rich plutonic rocks that lack sufficient olivine (40%) to be considered peridotites [Le Maitre et al., 2002].

Peridotites: Dense, Coarse-Grained Ultramafic Intrusive …

For instance, you can have garnet, pyroxene, or spinel peridotite/ kimberlite/wehrlite, etc. When a given mineral exceeds 50%, use peridotitic + dominant minerals. For example, you can have peridotitic chromitite or pyroxenite. Note: However, if a given mineral like pyroxene exceeds 60%, the rock becomes pyroxenite, which is darker.

The Pyroxene Mineral Group

Pyroxene minerals are primary or secondary constituents of many rocks used to make crushed stone, dimension stone, and architectural stone. Pyroxene is in the trap rock of the construction industry and in the "black granites" that are popular for making decorative tile and facing stone.

Pyroxenite

A pyroxenite is an ultramafic plutonic rock consisting of ≫60% pyroxene (either clino- or orthopyroxene, or both). Other phases include olivine, hornblende, micas, garnet, feldspar, spinel, ilmenite, and sulfides. They have a gradational relationship with peridotites.

The Ge abundance for silica-deficient pyroxenite M5-40 (gray star, Fig. 2B) was calculated assuming that the Ge/Si ratio of M5-40 is the same as the average Ge of D-MORB. The Ge content of secondary pyroxenite Px-1 (purple star, Fig. 2B) was obtained by mixing peridotite with eclogite-derived melt . The Ge contents for partial melts for all ...

Pyroxenite

Pyroxenite is an ultramafic plutonic igneous rock. Ultramafic means that more than 90% of the rock is composed of magnesium- and iron-rich minerals like pyroxenes, amphiboles, and olivine . In pyroxenite the dominant mafic mineral is a pyroxene.
