The Vøring Basin forms an integral part of the passive margin off central Norway. Three phases of extension and three phases of compression record the transition from rifting to sea-floor spreading between Norway and Greenland. The first regional extensional event is of Early Cenomanian age, causing relative uplift of the Gjallar Ridge and development of a regional depocentre in the Rås Basin. A second extensional event is represented by Late Campanian faulting on the Nyk High and along the Fles Fault Complex. A compressional event in the Late Maastrichtian led to inversion of the Râs Basin. This was followed by a regional extensional event in Late Palaeocene, leading to the continental break-up between Norway and Greenland in Earliest Eocene. After the onset of sea-floor spreading, the Vøring Basin has remained in overall compression, with two major compressional events identified in Early Eocene and Mid-Oligocene.
