"Grain size analysis from a drilling program at a study site 30 km west of Yellowknife defined three distinct groupings of sediments: a lowermost clay-rich unit (Group 1), a middle silt-rich unit (Group 2) and a sand-rich upper unit (Group 3). Physical properties, mineralogy and sediment texture were determined for two fine-grained clay samples from the lowermost unit. Analyses confirm that the two samples fall within Group 1, and are glaciolacustrine, originating from Glacial Lake McConnell (ca. 13.0 ¿ 9.5 ka), and derived primarily from local granitic bedrock. High ground ice contents imply these sediments may be prone to instability"--Provided by publisher. gccst Sediments gccst Minerals gccst Surficial geology gccst Geomorphology Aden, Ayana. Canada.
