“…B: In the North Sea there is overwhelming evidence for differential subsidence across Mesozoic faults, reactivated salt structures and active inversion zones during the Cenozoic (Clausen and Korstgård, 1993;Danielsen et al, 1997;Vejbaek et al, 2007;Korstgård et al, 1993;Petersen et al, 1992;Clausen and Huuse, 1999;Huuse, 1999;Ziegler, 1990;Vejbaek and Andersen, 2002;Rank-Friend and Elders, 2004 to mention a few). We question the dating of the differential subsidence across the major graben bounding faults (Rasmussen, 2004a) since the reconstruction did not consider differential compaction of sediments, and the maps of Rasmussen (2009) do in fact indicate much later activity.…”
