Figure F33. Core and X-ray CT images of a fault cutting mudstones in Unit 1 (interval 343-C0019E-1R-5, 62–76 cm). Fault surface is visible in core (left) as a planar polished surface with slickenlines that indicate normal slip. The fault is also visible in the X-ray CT image (right) as a bright band overprinted by a fracture (black void parallel to fault) that is likely a result of the coring process. Also visible in the core and X-ray CT image are open fractures at other orientations.
