Augite, also known as Augurite, is a common rock-forming pyroxene mineral with formula (Ca,Na) (Mg,Fe,Al,Ti) (Si,Al)2O6. The crystals are monoclinic and prismatic. Augite has two prominent cleavages, meeting at angles near 90 degrees. Augite is a solid solution in the pyroxene group.

Augite: Mineral information, data and localities. Named by Abraham G. Werner in 1792 from the Greek αυγή ("auge") for "shine" or "luster," in allusion to the appearance of its cleavage surfaces. Pyroxene Group, Clinopyroxene Subgroup.

What is Augite? 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 also found in ultramafic rocks and in some metamorphic rocks that form under high temperatures.

2019年3月15日 · Augite occurs chiefly as short, thick, prismatic crystals with a square or octagonal cross section and sometimes as large, cleavable masses. It occurs in a solid-solution series in which diopside and hedenbergite are the end-members.

Augite is an important rock-forming mineral, and large crystals are fairly common. It is the most widespread member of the pyroxene group, and it frequently alter s to many other minerals, including Hornblende, Chlorite, and Epidote. When altered to Actinolite, it is often called Uralite.

Augite, the most common pyroxene mineral (a silicate of calcium, magnesium, iron, titanium, and aluminum). It occurs chiefly as thick, tabular crystals in basalts, gabbros, andesites, and various other dark-coloured igneous rocks. It also is a common constituent of …

Augite is a clinopyroxene, part of a solid solution series. It is an intermediate member of diopside and hedenbergite. Vitreous, translucent. Black to dark green in hand sample. Usually colorless, tan-gray, pale green, pale brown or brownish green in thin section. May be zoned. Presence of tinanium darkens appearance. Short prismatic crystals.

Basic igneous and metamorphic rocks. Common world wide. Link to MinDat.org Location Data. From the Greek auge - "luster." Comments: Clear, dark gray augite prisms in matrix. Location: Isle of Ischia, near Naples, Compania, Italy. Scale: Size Not Given.

Augite is a type of dark-colored, calcium-rich silicate mineral. It has an orthorhombic crystal system and can be found in various igneous rocks such as basalt, gabbro, peridotite, and more. The stones are usually black or greenish due to their magnesium and iron content.

Augite is the most common mineral in the pyroxene family. It has many varieties due to the variation in chemistry possible in its complex coupled solid solution series. Augite is common in gabbroic and ultramafic rocks. It also forms large phenocrysts in many basalts.
