Definition of augite in English: augitenoun ˈɔːdʒʌɪtˈôjīt mass nounA dark green or black aluminosilicate mineral of the pyroxene group. It occurs in many igneous rocks, including basalt, gabbro, and dolerite. Example sentencesExamples - As cooling continues, plagioclase (a mixture of two kinds of aluminum silicates) and the pyroxene mineral augite (a magnesium silicate mixed with some iron) form.
- Minerals that remove Ti include augite and ilmenite/titanomagnetite.
- The most common phenocryst silicate phases are olivine, plagioclase and augite, typically, although not always, appearing in that order.
- The plagioclase feldspar weathers to produce a whitish gray rock, while the mafic minerals (olivine, augite and hypersthene) produce contrasting darker grains.
- The cpx is classified as augite based on average composition, and displays a very narrow compositional range.
Origin Early 19th century: from Latin augites, denoting a precious stone (probably turquoise), from Greek augitēs, from augē 'lustre'.
