Peridotite

This page is currently not sponsored. Click here to sponsor this page.
Peridotites are an ultramafic rock containing more than 40% olivine.

A general term for a coarse-grained plutonic rock composed chiefly of olivine with or without other mafic minerals such as pyroxenes, amphiboles, or micas, and containing little or no feldspar. Accessory minerals of the spinel group are commonly present. Peridotite is commonly altered to serpentinite.
