Figure F85. Photograph of thin normal faults (dipping steeply to the right) crosscutting and displacing an anastomosing parallel joint set (dipping steeply to the left) (interval 186-1150B-50R-3, 60-80 cm). Bioturbation gives displacement of minor normal fault in the upper part of the photograph. Abundant small and branching minor joints and faults are visible. At the bottom, an open fracture provides a view of fault surface with dark slickenside striae plunging in dip direction of the fault plane (interval 186-1150B-50R-1, 73-80 cm).
