(A) 3D block showing the main structural observations made on the mineralized quartz veins from Bonnac area. They allow us to propose a relative chronology of the structures developed in the paragneissic host-rock, the leucogranitic dykes and the quartz veins. (B) Stereogram (lower hemisphere projection) of the poles of the fault planes coeval with the emplacement of the mineralized veins, leucogranitic dykes, and late faults measured in the field.
