| Summary: | l fe ice km) ice-proximal, raised, marine delta in the eastern Canadian dating large boulders resting on the Aston delta surface using ver several cycles dform assemblages (20late Wisconsinan in the eastern Canadian Arctic. This view countered the prevailing Flint (1943) paradigm that envisionedArctic, is intrinsically related to the LIS (Løken, 1966). The delta is graded to a sea level 80 m higher than present and contains in situ marine bivalves dated>54,000 14C yr B.P. The shoreline associated with the Aston delta extends continuously for more than 70 km along the Aston Lowland and is visible on satellite imagery. A complex assemblage of coeval landforms is linked to the shoreline, including numerous glacial meltwater channels that grade to the shoreline and to other smaller deltas at the same elevation. |
