Essential in mafic igneous rocks, basalt,gabbro; common in ultramafic rocks; in some high-grade metamorphic rocks andmetamorphosed ironformations.
Augite is a mineral of interest togeologists, and collectors. While it has little to no industrial value, thepresence and development of augite may help tell scientists and geologistsabout Earth’s history in certain regions.

Augite, also known as Augurite, is a common rock-forming pyroxene mineral with formula (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2 O 6. The crystals are monoclinic and prismatic. Augite has two prominent cleavages, meeting at angles near 90 degrees.
Augite is a rock-forming mineral that commonly occurs in mafic and intermediate igneous rocks such as basalt, gabbro, andesite, and diorite. It is found in these rocks throughout the world, wherever they occur.
Augite is a rock-forming mineral of the pyroxene group commonly found within igneous and metamorphic rocks. Because its chemical structure is highly variable, augite might be considered by some to be its own group of minerals rather than an individual mineral.
