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.

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.

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.

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.

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 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.

Augite is a mineral. The mineral's name comes from the Greek word augites, meaning "brightness". However, augites only look shiny some of the time. Most augites have a dull (dark green, brown or black) color. Augite is a pyroxene.

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.
