Upper Jurassic coal-bearing shoreline deposits,Hochstetter Forland,east Greenland

Upper Jurassic coal-bearing yellow sandstones occur at several localities on Hochstetter Forland, northern east Greenland. The sandstones have been divided into eight sedimentary facies, each facies characterized by an assemblage of sedimentary structures, a specific lithology and, occasionally by the content of fossils, notably oysters. The interpretations of the established facies range from high subtidal oyster banks over intertidal beach sand to lagoonal and coastal swamp deposits. The sedimentary facies occur in a vertical sequence where two slightly different facies associations could be discerned. It is suggested that both facies associations have been deposited in a barrier—lagoon coastal area characterized by minor shoreline oscillations. The palaeogeographic setting of the investigated sequence in the fault-controlled basins along the east Greenland continental margin is discussed.
