Anse de Saint-Nicolas outcrop. (a) Picture of the cliff on the west side of the Anse de Saint-Nicolas showing B.U. covered by SU2 and NW-SE sinistral faults and N-S normal fault hosted in the B.U. crosscut by the unconformity. (b) Interpreted orthoimage of the rocky shelf made of B.U. to SU4 with weighted rose diagrams. SU2 hosts WNW-ESE normal faults and NE-SW brecciated structure with pyrite. (c) Orthoimage extract showing WNW-ESE fractures abutting on NE-SW faults in B.U. with weighted rose diagrams. (d) Orthoimage extract showing N-S fractures abutting on and crosscutting WNW-ESE fractures locally filled by barite with weighted rose diagrams. (e) Picture of a fault mirror of a WNW-ESE normal fault with a pyrite patch and a zoom with vertical slickenside. (f) View of a barite vein in B.U. (g) Picture of barite filling E-W fractures in veins and geodes crosscut by E-W and NNW-SSE pyrite vein. (h) Stereographic projection of structure measured in B.U. (red lines) and SU2 (green lines). See Table 1 for brittle structure nomenclature.
