The Wandel Sea Basin in North Greenland was a part of the Boreal Sea during the Triassic period, forming the western margin of the northernmost Atlantic sea. Through a multidisciplinary dataset, including sedimentology, biostratigraphy, organic geochemistry, and sedimentary provenance, the evolution of the basin has been documented. The basin experienced marine deposition from the Dienerian to the Norian, with sediments sourced from the Greenlandic Caledonian basement and deposited on a 100 km wide shallow marine shelf during the Early Triassic.
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 including sedimentology, biostratigraphy, organic geochemistry and sedimentary provenance, allow to document its basin evolution. The Wandel Sea Basin was transgressed in the Dienerian with marine deposition prevailing until the Norian. Sediments were mainly sourced from the Greenlandic Caledonian basement and deposited on a 100 km wide shallow marine shelf during the Early Triassic. In Middle Triassic, oil-prone mudstones formed in oxygen-depleted deep shelf settings, including eastern Wandel Sea Basin. Detrital zircon U-Pb ages show that by Carnian times, the >1000 km wide, Uralian-sourced, deltaic shelf had prograded westward across the Barents Sea reaching the eastern north Greenland and de facto nearly closed the northernmost Atlantic Sea.
