enstatite

en·sta·tite

E0156800 (ĕn′stə-tīt′)n. A glassy, usually yellowish gray variety of orthopyroxene having a magnesium silicate base, mainly MgSiO₃, usually found embedded in igneous rocks and meteorites.

[Greek enstatēs, adversary (because of its refractory quality) : en-, in, at, near; see en-² + -statēs, one that stands; see stā- in Indo-European roots + -ite.]

enstatite

(ˈɛnstəˌtaɪt) n (Minerals) a grey, green, yellow, or brown pyroxene mineral consisting of magnesium silicate in orthorhombic crystalline form. Formula: Mg2Si2O6[C19: from Greek enstatēs adversary (referring to its refractory quality) + -ite¹]

en•sta•tite

(ˈɛn stəˌtaɪt)

n. a yellow-green fibrous mineral, magnesium silicate, MgSiO₃, a pyroxene found in magnesium-rich rocks. [1855–60; < Greek enstát(ēs) adversary] en`sta•tit′ic (-ˈtɪt ɪk) adj.

Enstatite

enstatite

[′en·stə‚tīt] (mineralogy) MgOSiO₂ A member of the pyroxene mineral group that crystallizes in the orthorhombic system; usually yellowish gray but becomes green when a little iron is present.

Enstatite

a mineral of the orthorhombic pyroxene group, last member of the isomorphic series enstatite, Mg₂[Si₂O₆]–hypersthene, [Mg, Fe]₂ [Si₂O₆]–ferrosilite, Fe₂[Si₂O₆]. Enstatite contains not more than 5 percent FeO. It is colorless, greenish, or yellowish and has a hardness of 5.5 on Mohs’ scale and a density of 3,100–3,300 kg/m³. Enstatite is an important rock-forming mineral of magnesium-rich magmatic rocks. It alters to serpentine and talc upon the action of hydrothermal solutions.
