Concentrically zoned mafic-ultramafic intrusion, composed mainly of plagioclase hornblendite (60%), olivine-plagioclase hornblendite (20%), and minor hornblende-plagioclase pyroxenite, olivine-hornblende clinopyroxenite, lherzolite and dunite (17% overall). The dunite core is surrounded by an envelope of sulphide-bearing ultramafic rocks, zoned laterally from inner spinel lherzolite through olivine-hornblende clinopyroxenite to outer hornblende-plagioclase pyroxenite.

Located about 130 km east of Aswan (Assuan).
