Experimental models of extensional forced folds

Single-layer and multi-layer clay models are used to study the development of forced folds above normal faults. Modeling results show that the deformation patterns associated with extensional forced folding depend on the dip of the underlying normal fault and the presence of layer-parallel detachments. The model-predicted deformation patterns are simlar to those of extensional forced folds from the Gulf of Suez and offshore Norway. This similarity suggests that the modelling results apply to extensional forced folds and can provide guidelines for interpreting field, well, and seismic data. -from Authors
