AbstractMineral exploration activity by Rio Tinto Canadian Exploration Ltd. in 1975 and 1976 generated good quality bedrock geological maps of the Gayna River Property, in the northern Mackenzie Mountains. These maps were included as part of mineral assessment reports submitted to the government of Northwest Territories. Geological features and observations illustrated in these maps have been digitally rendered into a GIS by the Geological Survey of Canada and are here provided as shapefiles and ArcGIS(TM) layer files for public use. Digitized geological features include: Rio Tinto informal map units, contacts, faults, areas of gypsum outcrop, areas of breccia outcrop, limits of mapping, structural cross-section locations, visited stations, lithologies, planar measurements, linear measurements, and significant mineral occurrences.
Summary(Plain Language Summary, not published)
This publication provides GIS-compatible files of bedrock geological features for the Gayna River Property, northern Mackenzie Mountains, explored by Rio Tinto Canadian Exploration Ltd. in 1975-1976 for Pb-Zn mineralization.
