Polished olivine in an 02753-AB OTS standard mount.
Olivine is a silicate which is formed early in the crystallization of a magma. It contains major amounts of magnesium, and often a small but significant amount of nickel, which is not normally found in silicates. The olivine series of minerals range from the magnesian end member, forsterite to the iron end member fayalite. This example contains about 92% of the forsterite end member. It is highly stable with good surface properties.
