Atane Formation (Greenland)

The Atane Formation is a geologic formation in Greenland. It preserves fossil insects of Elytrulum multipunctatum , ^[1] dating back to the Albian to Coniacian stages of the Cretaceous period. ^[2]

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. ^[2]
