Abstract: The geological map and database are derived from regional mapping in the Etanda Lakes (NTS 95C/16) 1:50 000 scale map area, as part of the Geological Survey of Canada's Central Foreland NATMAP project. Geological features represented by attributed points, lines, and polygons have been compiled into a GIS dataset suitable for stand-alone use, or integration with other data sets. User-defined attributes provide traditional geological map information with greater detail and enhancements such as explicit orientation data, location and description of curated samples, and lithologies at visited outcrops. The Etanda Lakes map area is situated at the southern end of the Franklin Mountains encompassing the Liard Range and the convergence of the Kotaneelee, La Biche, and Tlogotsho Ranges. The geology of the area is characterised by sedimentary strata, of Late Devonian to Early Cretaceous age, exposed in a series of asymmetrical box or kink folds whose geometry is controlled largely by the competence of the Carboniferous Mattson Formation. Structure in the area is dominated by the culmination of the Etanda Dome where several anticline trends converge. In the eastern part of the map area the Liard Range exposes a series of closely spaced box folds locally imbricated by thrust faults of minor displacement. The trend of structures in the Liard Range varies from NNW to NNE, following the curve of the range. Lower Cretaceous strata of the Kotaneelee syncline occupy the valley shared by Chinkeh Creek and Jackfish River. Stratigraphic features include the westward shale-out of the Flett and Prophet Formations into the Besa River Formation and the sub-Cretaceous unconformity, which cuts out Permian strata to the north. The distinctive Chinkeh Formation at the base of the Cretaceous succession was mapped on both sides of the Kotaneelee Syncline. Purpose: Provided as part of a National Mapping (NATMAP) commitment to compile Geographic Information System products. Supplemental_Information: Points, lines, polygons, and attribute data representing the geology of the area covered by NTS map 95C/16 (1:50 000 scale) in southeastern Yukon Territory and southwestern Northwest Territories, Canada.
