ABSTRACT Rifting models derived from Project PROBE’s (Proto-Rifts and Ocean Basin Evolution) East African rift system investigations are applied to various facets of the geology of the North Viking graben between lats. 59° and 62°N. Simple cross-sectional comparisons show striking similarities, particularly in regard to the occurrences of asymmetrical half graben and the creation of intrarift highs (accommodation zones) related to linking modes of adjacent half grabens. The positions of accommodation zones and structurally elevated platforms also are consistent and predictable by this application. A plausible evolutionary scenario and ready explanation for some midrift structures are derived by using a scheme of half-graben overprinting in space and time. The analysis also may provide a qualitative understanding of switching depositional patterns and facies in both space and time.
