Fig. 5: Silverpit Crater deformation pattern at Top Chalk Group.
From: Multiple lines of evidence for a hypervelocity impact origin for the Silverpit Crater
a True vertical depth subsea (TVDSS) structure maps generated from both the Greater NEP 3D and PGS SNS 3D MegaMerge seismic volumes. b Dip attribute map generated from the same horizon. Note concentric faults, with predominantly normal fault displacement to the north, west and south (example highlighted in blue), and predominantly reverse faults to the east (examples highlighted in green). Concave-to-the-east tangential faults (highlighted in red) are only found to the west of the crater (uprange direction). The yellow dashed line and arrow indicate the impact trajectory inferred from fault patterns. c Seismic profile across the concave-downrange faults, showing reverse movement on some faults (red). The line location and individual faults are shown on (b).
