Pyroxenite - Wikipedia
Pyroxenite is an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite, diopside, hypersthene, bronzite or enstatite. Pyroxenites are classified into clinopyroxenites, orthopyroxenites, and the websterites which contain both types of pyroxenes (see diagram below).

2023年4月23日 · Pyroxenite is an ultramafic igneous rock that contain pyroxene group minerals such as augite, diopside, hypersthene, bronzite or enstatite. This is a coarse-grained rock and that contains at least 90 percent pyroxene minerals.
Pyroxenite | Mafic, Ultramafic & Igneous | Britannica
Pyroxenite, dark-coloured, intrusive igneous rock that consists chiefly of pyroxene. Pyroxenites are not abundant; they occur in discrete inclusions, in layered sills (tabular bodies inserted between other rocks) and lopoliths (laccoliths with basin-shaped bases), in branching veins, in narrow.
Pyroxenite - Sandatlas
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.

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 Pyroxene Mineral Group - Geology.com
Pyroxene is the name of a group of dark-colored rock-forming minerals found in igneous and metamorphic rocks throughout the world. They form under conditions of high temperature and/or high pressure. Augite, diopside, jadeite and spodumene are four of the best-known members of the pyroxene group; however, the pyroxene group has many other members.
