A recently published review of African granulite facies rocks and charnockitic intrusives (Clifford, 1974) is supplemented by a consideration of certain detailed studies: geochronological data for Namaqualand, Uganda and Nigeria are considered in relation to available data from other African occurrences; studies of paragenetical mineralogy of rocks of specialized chemistry from Namaqualand and Rhodesia are highlighted; and the polyphase deformation in Namaqualand, Uganda and elsewhere is stressed. Finally, the economic aspects of granulites and intrusive charnockites are discussed.
