Dec 07, 2005 (A Wilson) - The kimberlite is a micaceous, coarsely porphyritic kimberlite containing high concentrations of olivine and picroilmenite macrocrysts and a phlogopite+titanomagnetite+dolomite groundmass. Microxenoliths of mantle derivation have also been observed. Geochemically the kimberlite is rich in Mg, Fe-group elements, Ti and Nb.
