TTG rocks of the Sangmelima region (Ntem complex, Congo craton) in southern Cameroon range in modal composition from rocks of the charnockitic suite, tonalites to granodiorites. They display a wide spectrum of SiO2 composition (54 - 76 wt%), defining intermediate varieties that tend to be metaluminous (0.56)
