LATE PLEISTOCENE STRATIGRAPHY AND DEPOSITIONAL-ENVIRONMENTS OF THE FYNSELV AREA, JAMESON LAND, EAST GREENLAND

Deposits of Late Pleistocene age were investigated near the Fynselv ri ver on the southwestern coast of Jameson Land. East Greenland. The dep osits are of fluvial, deltaic shallow marine and glacigenic origin. Fo ur stratigraphic units are recorded. Unit I consists of deltaic and sh allow marine deposits reflecting a relative sea level of at least 20 m above the present. Elevated fluvial deposits represent the subaerial part of the depositional system. The system existed during full interg lacial and subarctic conditions as indicated by remains of flora and f auna and unit I is correlated with the Langelandselv interglaciation ( isotopic substage 5e). Unit II consists of a till deposited by a glaci er in the Scoresby Sund Fjord during the beginning of the Early Weichs elian referred to as the Aucellaelv stade. The glacier probably melted in a marine environment. Unit III represents a marine delta system du ring the Hugin So interstade, and reveals a relative sea level of at l east 62 m above the present. Unit IV consists of till and kame deposit s assumed to be deposited by a glacier in the Scoresby Sund Fjord duri ng the Flakkerhuk stade, probably a Late Weichselian glacier advance.
