Figure 10. Main structures observed in the field: (a) fault plane filled by a microgranite; (b) normal fault plane filled by a quartzo-feldspathic vein in the stream bed of the Dorguene; (c) C3 shear affecting an amphibolite vein in the amphibole granite; (d) W-E oriented pegmatite vein in the Gomtalla syenite; (e) C2/S2 composite shear, the symmetrical boudin of the stretched-tailed quartzo-feldspathic level is noted; (f) parallel fracture planes followed by the Gambaka stream.
