Gold distribution in glacial sediments and soils at Boston Property, Nunavut, Canada. Abstract Geochemical exploration for gold in the Slave Structural Province, Nunavut, Canada is hampered by a complex cover of Quaternary sediments and a lack of information on the effects of glacial dispersion and periglacial conditions on gold distribution. The principal surficial materials are till with a discontinuous veneer of post-glacial marine sediments. In areas of shallow overburden, frost boils mix weathered bedrock with drift and bring bedrock fragments to the surface. Samples were collected from till and from soil profiles on lines across the mineralized zone.
Anomalies are absent in marine sediments.
Anomalous values extend at least 2 km down-ice from the gold mineralization. The -53 m fraction should be analyzed for gold with a detection limit of 1 ppb or lower.
