Field view of granitic dykes and veins in regard to deformation. (a) NW-SE granitic vein crosscutting the migmatitic gneiss emplaced during normal shearing (N35°18’38”, W04°56’48). (b) N-S granitic dyke crosscutting the Beni Bousera metamorphic unit, emplaced during normal shearing (N35°12’02”, W04°50’29”). (c) E-W granitic dyke showing normal kinematic at the serpentinized peridotites wall (N35°18’29”, W04°54’29”). (d) deformed granitic dyke by an inverse left-lateral strike-slip fault in the peridotites. (e) granitic dyke affected by normal left-lateral strike-slip fault and by spaced cleavage in the serpentinized peridotites (N35°12’40”, W04°50’13”). (f) E-W fold affecting a spaced planar fabric in the serpentinized peridotites (N35°12’43”, W04°50’07”).
