Abstract
Effects of the earliest Tethyan and Arctic-North Atlantic rifting phases on the Early Triassic succession of the Central European Basin are particularly well recorded by unconformities, which form widespread sequence boundaries. Stratigraphic loss related to these unconformities may comprise entire Lower and Middle Buntsandstein formations most obviously developed in areas occupied by fault-controlled intra-basinal highs (swells). Analysis of 3D-seismic data and well logs combined with high-resolution sedimentological logging of drillcores at the western margin of the Ems Trough (NW Germany) reveals details of synsedimentary tectonic control on sequence development. Early Triassic extensional faulting of basement blocks provided stepwise addition of accommodation for continental sequences by growth faulting along north-south trending fault zones blocks on the flanks of the East Netherlands High. This process is most evident during the development of the Hardegsen Unconformity, which is characterized by an amalgamation of succeeding unconformity surfaces in areas of structurally controlled intrabasinal highs. The mainly aeolian toplaya-type sedimentary facies of the Middle Buntsandstein succession suggests very low intrabasinal relief and implies a constant reworking and levelling of the palaeo-surface. Consequently, the development and preservation of stratigraphic units is primarily determined by the potential accommodation provided by synsedimentary tectonics. © 2005 URBAN-VERLAG Hamburg/Wien GmbH.
