Olivine, of which peridot is a type, is a common mineral in mafic and ultramafic rocks, and it is often found in lavas and in peridotite xenoliths of the mantle, which lavas carry to the surface; but gem quality peridot only occurs in a fraction of these settings. Peridots can also be found in meteorites.

The first minerals are alkaline, mafic and ultramafic, such as olivine/olivinite, pyroxenes, alkaline feldspars such as labradorite and anortite and hornblende. These minerals are poor in silicic acid, silica, and their crystallisation makes the remaining magma more acidic.
