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

Kimberlites: From Deep Earth to Diamond Mines

Elements, 2019
Kimberlites are rare, enigmatic, low-volume igneous rocks. They are highly enriched in magnesium, volatiles (CO2 and H2O) and incompatible trace elements and are thought to be the most deeply derived (>150 km) magmatic rocks on Earth.
