The structural outline of the Horn Graben

Abstract

The structural outline of the Horn Graben is discussed on the basis of four seismic lines and the Danish North Sea wells R-1, S-1 and C-1. The basic outline of the general N-S trending Horn Graben is defined by several deep-seated faults established during the Early Permian or possibly pre-permian. During the Late Permian, Triassic and Jurassic, these faults were reactivated, and created in the southern area an asymmetrical graben with a very pronounced western flank. The western flank becomes less pronounced towards the north, where the tectonic activity created an asymmetrical graben with a pronounced eastern flank
