A GIS dataset of geological features from mineral exploration of the Gayna River Property by Rio Tinto Canadian Exploration Ltd., 1975-1976, northern Mackenzie Mountains, Northwest Territories

Abstract

Mineral 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.
