The Quaternary history of Banks Island, NWT, Canada.

Abstract

Banks Island is a polar desert where continental ice sheets spreading from a dispersal centre to the SE reached their maximum extent on at least three occasions. In each case the glacial episode was preceded and followed by a marine episode. The three successive glacial episodes are the Banks, Thomsen, and Laurentide. The last two were separated by the Cape Collinson interglaciation. Lobes of ice of Laurentide age impinged on different parts of the Island, and morainic systems related to these lobes are described, and in some cases divided into two stades.-after Author
