Abstract
Two main theories for the origin of the thick bodies of massive ground ice know to exist in the western Canadian Arctic are: 1) segregation-injection and 2) buried glacial ice. Because buried glacial ice may contain significant quantities of stratified debris and many have experienced thawing and freezing (regelation) on several occasions, it may be very difficult to distinguish between massive segregated ice and buried basal glacier ice. By use of cryostratigraphic and cryotextural (petrofabric) observations, massive ground ice bodies observed in the Sandhills Moraine, southern Banks Island, and the southern Eskimo Lakes region, Pleistocene Mackenzie Delta, are both interpreted as basal glacier ice. Other massive ground ice bodies which have been examined in the western Canadian Arctic are best explained in terms of segregation-injection.
