Kimberlite, as originally described by Lewis (1887, see Dawson, 1980) was a serpentinized, ultrabasic, phlogopite-bearing, diamondiferous volcanic breccia found at the Kimberley diamond mine, S Africa.The term blue ground refers to unoxidized slate-blue or blue-green kimberlite that occurs below the superficial oxidized zone. Since its original description, "kimberlite" has been extended.

Kimberlites tap the deepest recesses of our planet that we can sample. Propelled by a formidable volatile load, kimberlite melts transit hundreds of kilometers of mantle and crust, perhaps in just a few days, to form unique ballistic deposits at Earth's surface. Kimberlites accumulate and transport ripped-up bits from throughout most, if not.

Kimberlite is the name given to a silica-poor and magnesium-rich extrusive igneous rock (e.g., a volcanic rock) that contains major amounts of olivine, often serpentinized. It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces. Kimberlite may occur in the field as dikes or pipes that crystallize near but below the surface.

Lamprophyre. Lamprophyres (from Ancient Greek λαμπρός (lamprós) 'bright', and φύρω (phúrō) 'to mix') are uncommon, small-volume ultrapotassic igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks, and small intrusions. They are alkaline silica - undersaturated mafic or ultramafic rocks with high magnesium oxide.

Gabbro and norite are basic intrusive rocks composed principally of calcic plagioclase and pyroxene, with or without olivine. In gabbro the dominant ferromagnesian mineral is clinopyroxene, whereas it is orthopyroxene in norite. The expression "gabbroic rocks" includes both gabbro and norite. Gabbro is the coarse-grained, plutonic.
