The studied volcanic outcrops are constituted by lamproites composed by forsteritic olivine, Ti phlogopite, diopside,
enstatite, richterite with Ti and K, leucite, and Fe-rich sanidine.
Minor diopside and
enstatite are also observed in some dunites.
Their mineralogical composition is olivine (partly serpentinized), diopside, subordinate
enstatite, and Fe-oxides.
Also in the KARP room were a dozen loose crystals of
enstatite from Mogok which, for only about $100 tops, were remarkable bargains, considering that they are gemmy euhedral crystals of a rock-forming silicate species almost never seen as free-standing crystals at all.
Chromitite is a rock which consists, essentially, of the mineral chromite and a pyroxene mineral which usually has the approximate composition of
enstatite, a silicate of magnesium, ([MgO.
Thermometry of the A15/4 diopside using the
enstatite solvus (Nimis & Taylor 2000) indicates at least 42% of grains in the diamond zone.
254 nm could be related to
enstatite (Downs, 2006); others at ~1, 0.
The harzburgite consist of
enstatite 25-30 Percent , olivine 5 - 10 Percent , serpentine 55-60 Percent and spinel 3-5 Percent .
Scientists had thought that most of the bodies that merged to make Earth formed from a narrow zone in space and were similar to each other, belonging to a subclass of meteorites called
enstatite chondrites.
The new mineral, dubbed "Wassonite," was discovered inside the Yamato 691
enstatite chondrite meteorite by American researchers from NASA as well as scientists from Japan and South Korea.
Besides, thermal treatments at 1200 up to 1600 AC and the presence of
enstatite, which can be introduced adverse side-effects, are essential to achieve forsterite structures.
Steins is as an E-type asteroid, with a surface dominated by the silicate mineral
enstatite.
