Kimberlites

Kimberlites: From Deep Earth to Diamond Mines. 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. Kimberlites occur in ancient and thick continental lithosphere ...

Seul 1 % de la kimberlite est économique et on la trouve presque toujours dans ou au-dessus des cratons archéens.

Kimberlite genesis from a common carbonate-rich primary …

Kimberlites are carbonate-rich volcanic rocks derived from low-degree melting of the mantle, which have a unique place in the Earth Sciences, because they represent the deepest sourced melts [>150 to 250 km; e.g., (1, 2)] and are the major host for diamonds.On their journey to the surface, kimberlite magmas entrain a range of mantle …

Kimberlite Volcanism | Annual Reviews

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. Kimberlite magmas decrease temperature by a few hundred degrees during ascent. Changes of melt composition can …
