Bedrock weathering features in a portion of eastern high Arctic Canada: their nature and significance

Auteur :
WATTS, S.

Description :
Highly weathered pre-Cambrian bedrock has been reported from scattered localities across Arctic Canada during the past decade. As part of a study on weathering processes under arid conditions, field studies are reported on similar terrain in the Alexandra Fjord-Cape Herschel area of east-central Ellesmere Island. Particular emphasis is placed on the influence of bedrock, lithology and mineralogy on the intensity of physical disintegration under cold arid conditions. Preservation of certain remnant weathering features in upland summit areas under cold-based glacial ice is postulated.
