Kimberlite Volcanism

Annual Review of Earth and Planetary Sciences, 2013
Kimberlite magmas are volatile-rich, silica-poor ultrabasic magmas originating as small-degree mantle melts at depths of 150 km or greater. Alteration and entrained xenoliths obscure their original magma chemistry and properties.

Indian kimberlites and the genesis of kimberlites

Chemical Geology, 1984
Abstract Late Proterozoic kimberlites occur in both southern and central India. They are similar in petrography and geochemistry to the kimberlites of southern Africa and Yakutia, U.S.S.R. These rocks contain low-CaO forsteritic olivines (Fo92), abundant phlogopites, magnesian ilmenites, aluminous—magnesian chromites, chrome-pyrope garnets surrounded

Compositional classification of ?kimberlitic? and ?non-kimberlitic? ilmenite

Lithos, 2004
Abstract Ilmenite is one of the common kimberlitic indicator minerals recovered during diamond exploration, and its distinction from non-kimberlitic rock types is important. This is particularly true for regions where these minerals are present in relatively low abundance, and they are the dominant kimberlitic indicator mineral recovered.

The nature of erupting kimberlite melts

Lithos, 2009
The compositions of kimberlite magma and associated melts during eruption and hypabyssal intrusion are elusive due to contamination by xenolithic material and strong alteration, notably by serpentinisation.
