Description

Augite was discovered in 1792 by Abraham Gotlobb Werner, a German geologist who is famous for his theory of the history of the Earth, called Neptunism. The name augite originates from the Greek word auge or augites meaning shine or luster due to the appearance of its cleavage surfaces. It is a silicate mineral and is the most common member of the pyroxene group. Augite is a common rock-forming mineral, usually dark in color, ranging from green to black. A very widespread mineral, it is mainly found as thick, tabular crystals in igneous rocks such as gabbros, dolerites, and basalts, among other pyroxenes such as orthoclase, sanidine, labradorite, olivine, leucite, and amphiboles. In metamorphic rocks, augite is found in amphibolite, hornblende gneiss, and granulites. Although augite does not have any major commercial uses, it is sought after by collectors and is often a part of geological research.
