Abstract Detachment fault systems typically record displacements in the order of 10s kilometers. The principles that control growth smaller magnitude normal faults are not fully applicable to evolution detachment systems. We use interpretation 2D and 3D seismic reflection data from mid‐Norwegian rifted margin investigate how structural a interacted with effects isostatic footwall rollback produce complex geometries configuration associated supradetachment basins. further lateral interaction...
Abstract Observations and modelling results from highly extended regions indicate that detachment fault systems recording displacements of 10 km or more become associated with footwall uplift back‐rotation. This is commonly explained by the rolling hinge model, which predicts back‐rotation severe dip reduction (<20°) controlled amount extension. Although faults within necking domains at rifted margins often record in orders consistent those for it rarely invoked to explain configurations....
Abstract Late to post‐Caledonian, Devonian extension remains unresolved in the SW Barents Sea, despite considerable knowledge from onshore Norway, East Greenland and Svalbard. We analyse intrabasement seismic facies high‐resolution 3D reprocessed 2D data investigate evidence for Caledonian deformation post‐Caledonian detachment faulting central Sea. These results are compared published potential field models analogue studies Svalbard Bjørnøya, substantiating that structures inherited...
&lt;p&gt;Extensional detachment faults, core complexes and supradetachment basins play major roles in the evolution of 3D rifted margin architecture. The successive incision basement from early to late stages is rarely explained 3D. One reason for this likely lack a unifying model how very large faults grow link laterally, this, turn, links temporal margin. As fault shape exerts fundamental control on syn-rift basin architecture, critical understand sedimentation associated...
&lt;p&gt;Within rifted margins, the necking domain corresponds to area where drastic reduction in basement thickness leads crust attain a wedge-shape. The crustal thinning occurs along detachment fault systems typically recording displacements order of 10s kilometers. These commonly shape taper and eventually break, is thinned 10 km or less. In recent years, it has become clear that evolutionary models for remain unsatisfactory as well-known principles smaller magnitude are not fully...
&lt;p&gt;Detachment fault systems recording displacements in the order of 10s to 100s km remain poorly understood compared smaller scale normal faults. The evolutionary models developed for growth and interaction Andersonian-type faults are not fully applicable these large-magnitude systems. Consequently, associated basins - so-called supradetachment still extensional half-graben basins.&lt;/p&gt;&lt;p&gt;Numerical analogue 2D modelling have shed light on mechanisms...
