Mineralogical characteristics
Olivine is considered an important petrogenic mineral, as it is present in much of the Earth’s crust. Olivine has also been found in iron and stony meteorites. In gem quality, olivine takes the name peridot, and its main source is found in Pakistan.
Olivine belongs to the group of neosilicates or orthosilicates, formed by isolated groups of silica tetrahedra. The minerals in the forsterite-fayalite solid solution series are called olivine.
The green color of olivine is due to its iron content. White and light tones are due to the iron of fayalite, and black or dark tones are due to the magnesium of forsterite.
Olivine usually forms in igneous rocks, such as basalt and peridot.
