Olivine. The mineral olivine (/ ˈɒl.ɪˌviːn /) is a magnesium iron silicate with the chemical formula (Mg, Fe)2 Si O 4. It is a type of nesosilicate or orthosilicate. The primary component of the Earth's upper mantle, [9] it is a common mineral in Earth's subsurface, but weathers quickly on the surface. Olivine has many uses, such as the ...
Serpentine minerals are often formed by the hydration of olivine-rich ultramafic rocks at relatively low temperatures (0 to ~600 °C). [15] The chemical reaction turns olivine into serpentine minerals. They may also have their origins in metamorphic alterations of peridotite and pyroxene.

Olivine is most abundant in the upper mantle, above about 410 km (250 mi); the olivine polymorphs wadsleyite and ringwoodite are thought to dominate the transition zone of the mantle, a zone present from about 410 to 660 km
