dc.description.abstractThe Ling Depression is a structural feature with a unique orientation in the Central North Sea which depicts the trend and linkage of deep extensional zones with the overlying structures. The Ling Depression is studied and analyzed to extract information leading to the geological evolution of the study area. The data of regional seismic lines along with borehole information was assembled and used for the structural and stratigraphic analysis. Mapping of the key horizons was performed and time-structure maps along with time-thickness maps were generated. Further onwards, detailed analyses on different fault geometries and style of faulting were carried out. These exercises facilitated in extracting in-depth details of the key structural elements and finally comprehend the geological evolution of the Ling Depression and the adjacent highs. Horst geometries are interpreted which are bounded by deep-rooted brittle faults, probably linking with a major Devonian basement shear zone, the Hardangerfjord Shear Zone. Some clear rotated half-grabens are observed below the Base Zechstein within the Ling Depression. Large salt diapirs breaching into the Mesozoic-Cenozoic stratigraphy mostly in the SW of the study area are also noticed. Large-scale monoclinal fold structures are interpreted at the shallower stratigraphic level in the study area. The primary depo-centers are determined using the time-thickness maps between the certain stratigraphic levels. In the light of the obtained results, it is assumed that the basement shear zones of the Early Devonian age have played an important role in shaping the local geometries and features in the study area. Major half-grabens observed are confined to the Late Carboniferous-Early Permian rifting event along with the reactivation of certain deep-rooted fault geometries. The Zechstein salt has acted as décollement, hence separating Jurassic rifting from the Late Carboniferous-Early Permian rifting, which all together affected and evolved the local structural elements. Alpine compression further introduced inverted structures and faults in the Ling Depressioneng
