Diamicton is interpreted as glacial till; other facies are fluvial/ glaciofluvial in origin. Sediments have a number of geomorphic settings, including: 1) Holocene colluvium, alluvial fans and stream deposits; 2) Reid periglacial alluvial fans; and 3) pre-Reid glacial and glaciofluvial deposits. Previous workers suggested that significant placer gold concentrations occur only in alluvium that lies either upon bedrock or glacial till. New data from this study suggests that significant amounts of placer gold also occur in the diamicton, primarily at the diamicton/bedrock contact. Gold concentration in the diamicton is likely due to glacial erosion and incorporation of a supergene-enriched bedrock mantle and pre-existing auriferous alluvium.xv, 272 leaves : ill. ; 30 cm.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
