We address the effects of oblique rifting on passive margin geometry using a combination of computer models, laboratory experiments and knowledge from seismic and geological observations. The laboratory experiments will be built of sand and silicone (resembling brittle and ductile crustal materials) in a new modelling laboratory at the University of Bern in Switzerland. The numerical experiments use 3D modelling software developed jointly at the Geological Survey of Norway and GNS Science in New Zealand. Our experiments are aimed at providing a new view on margin development, which is of direct relevance to margin hazard, hydrocarbon exploration and landscape development studies.
