Atane Formation (Greenland)

The Atane Formation is a geologic formation in Greenland. It preserves fossil insects of Elytrulum multipunctatum, dated to the Albian to Coniacian ages of the Cretaceous period.

Description

The carbonaceous mudstones, sandstones and coal seams are interpreted as freshwater lake or swamp deposits representing the vertical aggradation of a subaerial to shallow, limnic floodplain to upper delta plain. There are no indications –neither palynological evidence nor the presence of pyrite– to suggest marine or brackish-water conditions.
