Abstract
This chapter presents the seven tectonic events that affected the sub-Tertiary sedimentary cover. The 'Mid Cimmerian Unconformity' (MCU) reflects the widespread Aalenian 'Mid North Sea doming' event leading to the regional erosion of upper Triassic to Aalenian sediments in this region. This event leads to the detachment of the continental red beds of the Rotliegend syn-rift wedge from the underlying tabular Carboniferous and its inversion, with the fold above Fault 6 affecting the Rotliegend, Zechstein and Triassic to lower Jurassic sediments. Two different phases of regional easterly-tilting affected the sediments over the area between Fault 6 and Anticline B. The first phase is associated to the formation of Anticline A and with the hangingwall tilting associated with the activity of Fault 6. The second phase is related to the Aalenian regional uplifting, which had an increasingly greater magnitude towards the proto-Viking Graben, where the focus of the regional thermal doming and erosion was situated.
