Origin of olivine:

a mineral consisting of magnesium iron silicate; a source of magnesium
Any of a group of olive green magnesium-iron silicate minerals that crystallize in the orthorhombic system.
The mineral olivine, is a magnesium iron silicate with the formula (Mg,Fe)2SiO4. It is a common mineral in the Earth's subsurface but weathers quickly on the surface. The ratio of magnesium and iron varies between the two endmembers of the solid solution series: forsterite and fayalite. Compositions of olivine are commonly expressed as molar percentages of forsterite and fayalite. Forsterite has an unusually high melting temperature at atmospheric pressure, almost 1900 °C, but the melting temperature of fayalite is much lower. The melting temperature varies smoothly between the two endmembers, as do other properties. Olivine incorporates only minor amounts of elements other than oxygen, silicon, magnesium and iron. Manganese and nickel commonly are the additional elements present in highest concentrations. Olivine gives its name to the group of minerals with a related structure which includes tephroite, monticellite and kirschsteinite.
