“…12D), Maerten et al (2002Maerten et al ( , 2006 suggested that the curved geometry of the Oseberg and Brage East faults played a great role during the initiation of the NW-SE-striking minor faults. These NW-SE-striking faults are confined to the area between the Oseberg Fault and the fault to the west, and may possibly be explained as a result of the local, block-internal stress history during the general late Jurassic extension.…”

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.Both N-S-and NW-SE-striking faults were established during the Permian -Early

For instance, Kattenhorn et al (2000) demonstrated that, depending on the remote stress state, it is possible for a range of ancillary fault or fracture orientations to develop, recording variable amounts of extension parallel to the first-order faults.…”

Abstract. The mechanical interaction of propagating normal faults is known to influence the linkage geometry of firstorder faults, and the development of second-order faults and fractures, which transfer displacement within relay zones. Here we use natural examples of growth faults from two active volcanic rift zones (Koa'e, island of Hawai'i, and Krafla, northern Iceland) to illustrate the importance of horizontalplane extension (heave) gradients, and associated vertical axis rotations, in evolving continental rift systems. Secondorder extension and extensional-shear faults within the relay zones variably resolve components of regional extension, and components of extension and/or shortening parallel to the rift zone, to accommodate the inherently three-dimensional (3-D) strains associated with relay zone development and rotation. Such a configuration involves volume increase, which is accommodated at the surface by open fractures; in the subsurface this may be accommodated by veins or dikes oriented obliquely and normal to the rift axis. To consider the scalability of the effects of relay zone rotations, we compare the geometry and kinematics of fault and fracture sets in the Koa'e and Krafla rift zones with data from exhumed contemporaneous fault and dike systems developed within a > 5 × 10 4 km 2 relay system that developed during formation of the NE Atlantic margins. Based on the findings presented here we propose a new conceptual model for the evolution of segmented continental rift basins on the NE Atlantic margins.
