Kimberlite is a potassic to ultrapotassic ultramafic rock with inequigranular texture. It is a rare type of peridotite with many xenoliths and xenocrysts, including, on rare occasions, diamonds. Thus, many refer to it as a complex hybrid rock.See also dunite; kimberlite. Peridotite is the ultimate source of all chromium ore and naturally occurring diamonds, and of nearly all chrysotile asbestos. It is one of the main host rocks of talc deposits and platinum metals and formerly was a major source of magnesite.
