Devonian–Early Carboniferous thrust tectonics in the Old Red Sandstone Molasse Basin, North-East Greenland

Research output: Contribution to journalArticleResearchpeer-review


In East Greenland, sedimentation during the Middle Devonian-earliest Carboniferous interval was characterized by the Old Red Sandstone Molasse Basin deposits. The continental succession recorded folding and intrabasinal unconformities associated with the activation of extensional detachments and core complex formation which post-dated high-P granulite facies metamorphism at c. 403 Ma. The extensional collapse responsible for the initiation of the Devonian basin and associated bimodal magmatism must be understood in the context of continued continental convergence during the Early Carboniferous, required by ultrahigh-pressure metamorphism in North-East Greenland at c. 355 Ma. Along a small nunatak within the Wordie Gletscher in Payer Land, NE Greenland (lat. 74°N), Precambrian gneisses recording Devonian granulite-facies metamorphism are in tectonic contact with the molasse deposits along an ESE-ward dipping thrust fault: the Scotstounhill Thrust. This paper will discuss the role of Devonian contractional structures and contemporaneous extensional faulting and present a new tectonic model that accounts for the exhumation of deep crustal rocks by these coupled mechanisms.
