Book Description

Komatiite units dominate Archean volcanic successions in the Laughland Lake and Walker Lake map areas of the Committee Bay region, central Nunavut. This study describes results of regional & local mapping of some well-preserved komatiite sequences in those areas, particularly in the Laughland Lake area where the majority of the better-preserved komatiite units are found. Structural & stratigraphic relationships are also discussed.

Ice movement indicators have been carefully documented in the Arrowsmith River area of central mainland Nunavut, and this paper presents preliminary results of this research. It begins with background on the regional geological setting and on the field sampling methods used. Ice movement indicators & associated glacial landforms are then described, including striae, eskers, meltwater channels, moraine systems, and raised shorelines.
