Most important minerals in the olivine family and possibly the most important constituents of the Earth's mantle.

These minerals occur as green to yellow, glassy crystals in many basic and ultrabasic rocks (see acid and basic rocks) and are also abundant in chondritic meteorites. They also occur in dolomitic limestones, marbles, and metamorphosed iron-rich sediments. They are sometimes used in the manufacture of brick.
