Abstract
Quaternary sections exposed along the southwest coast of the Burin Peninsula, Newfoundland, have yielded critical information for prevailing ideas on regional glacial history, including multiple glaciations predating the Wisconsinan, Sangamonian marine transgression, restricted Newfoundland Ice Cap during the late Wisconsinan and a late-glacial onshore ice flow event. Given the rarity of pre-last glacial deposits in Newfoundland and the growing recognition that the island was completely inundated by Late Wisconsinan ice, it is important to re-evaluate the original data and interpretations on which these important conclusions were based. New field observations on coastal sections indicate much greater stratigraphic and sedimentological complexity than described by previous researchers, the occurrence of fossiliferous tills (39,810 Aħ 470 BP, Beta 237892; 39,370 Aħ 450 BP, Beta 237891) and a more substantial deglacial sedimentary record associated with onshore ice flow. Preliminary interpretations suggest that the entire sedimentary sequence exposed in coastal bluffs postdates the mid-Wisconsinan and was deposited in a deglacial tidewater environment associated with several ice flow events.
