enstatiteCommon silicate mineral in the pyroxene family. It is the stable form of magnesium silicate (MgSiO3, often with up to 10% iron) in magnesium- and iron-rich igneous rock types. Enstatite crystallizes in the orthorhombic system (three unequal axes at right angles to each other). enstatite [′en·stə‚tīt] (mineralogy) MgOSiO2A 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. Want to thank TFD for its existence?

No references found | At higher metamorphic grades, metamorphosed komattites contain anthophyllite, enstatite, olivine and diopside. Fresh semi-coke contains occasionally yellowish-green lumps of partially melted slag, which are composed of high-temperature Ca-Mg silicates--diposide, enstatite and various clinker-minerals ([beta]-C2S, C3S, merwinite and traces of Ca-ferrites). That mineral also predominates in a group of meteorites called enstatite achondrites. |
