664	G1KMB	Group-1-kimberlite - A type of kimberlite. Group-1-kimberlite corresponds to archetypal rocks from Kimberley, South Africa that formerly were termed basaltic kimberlites. These are volatile-rich (dominantly CO₂), potassic, ultrabasic rocks which commonly exhibit a distinctive inequigranular texture resulting from the presence of macrocrysts (and in some instances megacrysts) set in a fine-grained matrix.

665	G2KMB	Group-2-kimberlite - A type of kimberlite. Group-2-kimberlite corresponds to micaceous or lamprophyric kimberlites. They are characterised by the presence of macrocrysts, phenocrysts and groundmass micas, which vary from phlogopite to tetraferriphlogopite. British Geological Survey Research Report RR/99/06, section 6.4.	R	Group-2-kimberlite			GRBA	24-FEB-00	TMCM	22-FEB-19		Volatile-rich (CO2) K exotic intrusive rock; macro-/phenocrysts/matrix of phlog/tetrafephlog/ol, in matrix of +/-2nd diop/spin/chrom/magnet/perovs/apat/REE phos/Ti-ates/rut/ilmen/cal/dol/ancyl/norseth/serp, rare sani/richter; 2nd bar mica/lamprophyric kim	C
