In the south Kasai, archaean rocks affected (at 2.8 Ga) by granulite facies metamorphism consist of : — to the North, a large basic plutonic complex of gabbro-norites with subordinate anorthosites ; — to the South, acidic charno-enderbitic gneisses and granulite facies metasedimentary rocks crosscut by dolerite dykes. In the gabbro-noritic complex, magmatic structures are largely obliterated by the granoblastic recrystallization of most rocks in which garnet may occur either as grains or as thin reaction rims. Three main garnet forming reactions have been observed : (1) plag + cpx → gt + qz (2) plag + opx → gt + cpx + qz (3) amph + qz → gt + cpx (+ plag + ilm). In the anorthosites, typical coronitic textures developed around olivine...
