Kimberlite magmatism has occurred several times, one major episode of intrusion being in the Cretaceous. The accumulated evidence from both stratigraphic sources and radiometric dating is that certain geographical areas, usually coinciding with old cratons, have been subjected to intermittent kimberlite intrusion throughout geologic time.

Kimberlite is a volcanic rock containing isolated pieces of rock or crystal that were pushed up out of the earth's mantle by magma. Kimberlite can be identified by its fine-grain texture, its blue or yellow color, and/or the presence of diamonds and other gems in the rock.

A superplume generated by cooling processes in the mantle (LVZ = low-velocity zone). A mantle plume is a proposed mechanism of convection within the Earth's mantle, hypothesized to explain anomalous volcanism. Because the plume head partially melts on reaching shallow depths, a plume is often invoked as the cause of volcanic hotspots, …The 972 carats (194.4 g) Excelsior diamond, the largest found at the Jagersfontein Mine.
