| Abstract |
A late Quaternary stratigraphy has been established for the southern North Sea by the British Geological Survey and Rijks Geologische Dienst during joint compilation of 1:250,000 maps of the Quaternary Geology and Sea Bed Sediments of the area between 52° and 54° N, and 2° and 4° E. The deposits of the three regional glaciations of Northwest Europe are represented offshore. The Elsterian subglacial valley system of northern Germany continues across the southern North Sea towards eastern England; and the valleys, which are commonly more than 100 m deep offshore, have been filled mainly by EIsterian glaciolacustrine and fluvioglacial deposits. There was no connection across the southern North Sea between the Saalian and Weichselian ice sheets of northern Europe and eastern England. Periglacial conditions prevailed offshore during both of these glacial periods, except in the northwest where up to 15m of till was deposited during late Weichselian times. Marine sands and clays were deposited in the southern North Sea during the Holsteinian and Eemian interglacial periods. The sediments of the Holocene transgression have been subdivided into six formations on the BGS/RGD maps, based on their lithology and shell content. |
