Description

A family of coarse-grain igneous rocks composed of varying proportions of olivine and pyroxenes with a granite-like texture. Most peridotite rocks are a dull green to black in color. The yellow to light green dunite, is a special type of peridotite that contains a high percentage of olivine. Dunite is named for Dun Mountain in New Zealand. Significant deposits of peridotite are found in South Africa, Australia, Tanzania, and the U.S. (Arkansas, Georgia, Kentucky, California, Arizona, New York, New Mexico, North Carolina, Washington). Peridotite is a host rock for chromium ores, naturally occurring diamonds, chrysotile asbestos, talc, and native platinum.
