Abstract
Quantitative analysis of fossil formaminiferal faunas in raised marine deposits on Broughton Island, Baffin Island, reveals assemblages which can be correlated with Mid Weichselian (Mid-Würmian) foraminiferal assemblages from the Kola Peninsula of arctic USSR. This correlation is also supported by radiocarbon datings from the two areas and leads to the conclusion that a Mid-Weichselian (Mid-Wisconsinian) interstadial can be identified for Broughton Island. It is termed the Cape Broughton interstadial. During this interstadial the sea level at Broughton Island reached to at least 46 m above the present level, and the faunal diversity there ranged between 14 and 23, which is high for arctic areas. One site, on the east side of Broughton Island, has a fauna that indicates a greater age than those correlative with the Cape Broughton type assemblage. This deposit may be Sangamonian in age.
