Abstract The Neoarchaean (2.6 Gal K rich granitoids of the Ebolowa area (Ntem Complex, Congo Craton) in southern Cameroon form small massifs trending north-northwest-south-southeast to north-south and contain xenoliths of the surrounding tonalite-trondhjemite-granodiorite (TTG) series and of the greenstone belt country rocks. The granitoids range in modal composition from granodiorite to granite and leucogranite. The rocks display high SiO 2 (69–76.5%), Na 2 O+K 2 O (5.5–9.1 %) and K 2 O Na 2 O… CONTINUE READING
