Interpreted photographs of brittle structures in the Jard-sur-Mer area (Aquitaine Basin). P5: listric normal faults located near the discontinuity and crossing the Bathonian unit; P6: conjugated normal faults crossing the Bathonian unit; P7: high angle normal fault located forming the contact between Bathonian unit to the left and Callovian unit to the right; P8: barite and subsequent quartz fillings in a vertical vein in the Bajocian unit; P9 and P10: fault planes within the Bathonian unit. The geodic quartz and the striated quartz and barite suggest that faulting is coeval with mineral crystallization. See Figure 2 for the location of each picture.
