Triassic in the northernmost Atlantic—Linking North Greenland and the southwestern Barents Sea
Abstract The Wandel Sea Basin in North Greenland was part of the epicontinental Boreal Sea in Triassic time. The basin formed the western margin of the northernmost Atlantic elongated sea connecting southwards with basins along the conjugate Greenland—Norwegian margins. A multidisciplinary dataset i...
