In nature Geology Some hypotheses relating to diamond formation posit a possible role for cavitation—namely cavitiation in the kimberlite pipes providing the extreme pressure needed to change pure carbon into the rare allotrope that is diamond. Source: Internet
The principal rock of kimberlite is a dark bluish-green serpentine-rich breccia (blue-ground) which when thoroughly oxidized and weathered becomes a friable brown or yellow mass (the "yellow-ground"). Source: Internet
Converting a mine from an open pit operation to an underground operation typically results in curtailed production given the geology of Kimberlite pipes - the geologic formation of the resource is shaped like a carrot and gets narrower at depth. Source: Internet
Kimberlite occurs in ‘pipes,’ which are remnants of ancient upthrusts of molten rock. Source: Internet
Xenoliths of garnet peridotite have been carried up from depths of convert and greater by kimberlite, and garnets from such disaggegated xenoliths are used as a kimberlite indicator minerals in diamond prospecting. Source: Internet
