A newly discovered mid-Carboniferous - ?early Permian reef complex in the Wandel Sea Basin, eastern North Greenland

Abstract

Three types of carbonate build-ups occur in the mid-Carboniferous – ?early Permian (Moscovian–?Asselian) succession at Kap Jungersen, southern Amdrup Land, North Greenland: (1) Palaeoaplysina-dominated build-ups; (2) AIgae-dominated build-ups; and (3) Bryozoan-dominated build-ups. The build-ups are less than 15 m thick and up to a few hundred metres wide. They often coalesce to form laterally widespread, build-up dominated units and are locally stacked to form up to 100 m thick build-up dominated sections along platform margins.
