A new occurrence of Plio-Pleistocene marine fossiliferous sediments from Jameson Land, East Greenland, is described and named the Lodin Elv Formation. The sedimentary sequence consists of sorted sand and silt overlain by diamicton containing erratic boulders. Both units contain in situ molluscs and foraminiferal assemblages. The sediments occur as an erosional remnant of local distribution, covered by Holocene deltaic sand, and probably rest on Jurassic shale. The thickness is c. 40 metres. The formation is dated faunistically by its foraminiferal faunas, which are correlated with occurrences in the North Sea and on Baffin Island. The suggested age is supported by amino acid analyses of mollusc shells. The Lodin Elv Formation records the earliest known evidence of glaciation and arctic conditions in Greenland in post-Precambrian time.
