Predictive Surficial Geology: Marian River, NTS 85-N, Northwest Territories; Geological Survey of Canada, Open File 7543, 1 .zip file. doi:10.4095/294923. Online_Linkage: Description: Abstract: Surficial material and geology maps provide important geoscience information required for geological reconstructions, mineral exploration and development and land use planning in northern Canada. In this study, remote predictive mapping was used to derive predictive surficial material and surficial geology maps for Yellowknife NTS 85J, located within the Slave Geological Province. The predictive maps were generated using radiometrically balanced LANDSAT 7 imagery and knowledge gained from airphoto interpretations, field observations and legacy datasets. This Open File contains graphical and digital georeferenced versions of the predictive maps. A printable version of the predictive surficial geology map is also provided in pdf format (map scale 1:125 000). Purpose: This study was undertaken to produce predictive surficial material and surficial geology maps within Yellowknife NTS 85J. Despite the detailed knowledge of bedrock geology in the mineral-rich Slave Geological Province, knowledge of surficial material and surficial geology remain rudimentary. The lack of this geoscience information limits the ability to assess terrain risks associated with various surficial materials and identify granular aggregate along proposed and existing infrastructure corridors (e.g. northern roads). The derived maps may be used for future field mapping campaigns, geotechnical investigations and mineral exploration. Supplemental_Information: Data set is in English.
