Objective(s): This project is a large multi-agency, multidisciplinary effort to study 2 geoscience transects across the foothills in northeastern British Columbia, southern Yukon and Northwest Territories. The primary purpose is to map bedrock and surficial geology at 1:50,000 and 1:250,000 scales, by determining the distribution of rock units and identifying their ages, stratigraphic positions and facies changes. Also, detailed analysis of specific rock units will be used to develop generalized maps of the regional geography at various times in the geological past. These maps will form the basis of a model of the evolution of the Cordilleran mountain system. The mountains formed because the rocks were bent, broken and uplifted by northeastward compression. The shapes, sizes and orientations of these structures change dramatically from northern BC into the Territories, and we are testing the hypothesis that these changes reflect deeper crustal controls. An important part of the mapping is the definition of the ages, attitudes and transport directions of the folding and faulting.
Project Description: This project is a large multi-agency, multidisciplinary effort to study 2 geoscience transects across the foothills in northeastern British Columbia, southern Yukon and Northwest Territories. The primary purpose is to map bedrock and surficial geology at 1:50 000 and 1:250 000 scales. The base of operations will be at Fort Liard and camps will be accessed by helicopter. Fly camps will be visited by 2-4 crew members for about 1 week. From the fly camps the crew will travel about 5-10 km by foot usually following ridge crests and stream valleys. Some river crossing may be attempted using a rubber boat (Zodiak) with a small outboard motor and/or paddles. Measurements include detailed descriptions of stratigraphic sections and limited rock sampling (fist sized samples).
