Influence of fault reactivation during multiphase rifting: The Oseberg area, northern North Sea rift

摘要

Multiphase rifts tend to produce fault populations that evolve by the formation of new faults and reactivation of earlier faults. The resulting fault patterns tend to be complex and difficult to decipher. In this work we use seismic reflection data to examine the evolution of a normal fault network in the Oseberg Fault Block in the northern North Sea Rift System a rift system that experienced Permian Early Triassic and Middle Jurassic Early Cretaceous rifting and exhibits N-S, NW-SE and NE-SW oriented faults.
