Definition of enstatite in English:



mass noun
  • A translucent crystalline mineral that occurs in some igneous rocks and stony meteorites. It consists of magnesium silicate and is a member of the pyroxene group.

    • ‘Some of the characteristic minerals found in kimberlite are olivine, pyrope garnet, enstatite, diopside, ilmenite, phlogopite, perovskite, magnetite, and spinel.’
    • ‘Other associated minerals include olivine (commonly altered to serpentine), phlogopite, enstatite, and many other trace accessory minerals.’
    • ‘The Herbeira websterites contain diopside, enstatite, and pargasite with olivine, garnet, spinel, magnetite and ilmenite as minor phases.’
    • ‘The condensation of iron metal alloy and magnesian silicates (MgSiO 3, enstatite, and Mg 2 SiO 4, forsterite) divides the refractory elements from the moderately volatile elements.’
    • ‘In addition to the enstatite, forsterite, and PAHs, they are trying to model their spectra using a library containing dolomite (a carbonate), smectite (a clay), spinel/hibonite, pyrrhotite, iron oxide, and elemental carbon grains.’


Mid 19th century from Greek enstatēs ‘adversary’ (because of its refractory nature) + -ite.
