This deformation led to the exhumation of the accretional basal prism in the middle Permian, and to the obduction of a part of the subducted palaeo-Pacific oceanic crust onto the Gondwana continental margin.
Thus the obduction during Upper Cretaceous of the Santa Elena-San Juan ophiolite on a yet thickened crust cannot be ruled out.
Obduction of the Lushs Bight oceanic tract was followed by generation of the Tremadoc (489-484 Ma; Dunning and Krogh 1985; Cawood et al.

It takes us through to the development of the Appalachian Mountains and the formation of Pangea, with stops in between, such as the obduction of ophiolites exposed at the UNESCO World Heritage Site in Gros Morne National Park, western Newfoundland.
In similar way, De Boer (1979) interpreted the Nicoya Complex as emplaced by obduction, but with a few evidences that supported their interpretation.
2002a) with its cover of Miramichi strata (peri-Gondwana) led to obduction of the arc perhaps as many as hundreds of kilometres to the southeast.
Waheed and Wells (1990) suggest an early manifestation of the paleodrainage shift due to obduction and shelf reversal recorded in the broadly distributed and marginal marine early Eocene Ghazij Formation in western Pakistan.
This mechanism has since become known as obduction, in contrast to subduction.
The gravity anomalies are consistent with a complex evolution for northwestern South America involving the accretion of an oceanic plateau with strong Caribbean affinities, obduction of the oceanic crust, over thrusting and strike-slip faulting.
