Hence, the crystallizing olivine was Mg-rich, and igneous rocks rich in forsterite were formed.
12.
It is believed to be made up of metallic iron, FeSi, silicon carbide, and forsterite.
13.
Other minor components which can form during progressive crystallization are belite, monticellite, rankinite, wollastonite and forsterite.
14.
Ringwoodite, the high pressure forsterite polymorph named after Ted Ringwood was discovered in fragments of the Tenham meteorite.
15.
Dehydration is complete at about, with the final products being forsterite ( magnesium silicate ), silica and water.
16.
These minerals include chromite, pyrope, diopside, picroilmenite, forsterite, orthopyroxene, as well as small diamonds.
17.
Associated minerals include calcite, dolomite, grossular, wollastonite, talc, diopside, forsterite, cummingtonite, riebeckite and winchite.
18.
The usual cumulate mineralogy is highly magnesium rich forsterite olivine, though chromian pyroxene cumulates are also possible ( though rarer ).
19.
Forsterite has an unusually high melting temperature at atmospheric pressure, almost, but the melting temperature of fayalite is much lower ( about ).
20.
The metamorphism of impure dolomite or other sedimentary rocks with high magnesium and low silica content also produces Mg-rich olivine, or forsterite.
