It is generally thought that such ‘dunitic nodules’ originate from the base of the cratonic lithosphere and that their formation marks the onset of deep-rooted kimberlite magmatic plumbing systems. However, thermobarometric constraints to support such a …The name is derived from Kimberley, South Africa. A polymict megacryst-rich ultramafic volcanic breccia, consisting of major amounts of serpentinized olivine, with variable amounts of phlogopite, carbonate, garnet (e.g. pyrope), orthopyroxene, clinopyroxene, chromite and oxides.

Diamonds are known to occur in a variety of rocks, including high-pressure metamorphic rocks such as garnet- biotite gneisses of northern Kazakhstan, alpine-type peridotites, and meteorites. However, the only known economically significant primary sources of diamond are kimberlite and lamproite.

Kimberlite volcanism involves the emplacement of olivine-rich volcaniclastic deposits into volcanic vents or pipes.
