Objective(s): This study aims to describe the formation of a very large depression that covered most of north-western Canada 1.7 billion-years ago. This will be helpful to understand the geological evolution of the Canadian Shield, and ultimately, how Earth formed, how it changed through time and how it will evolve in the future.

Project Description: This study aims to describe the formation of a very large depression that covered most of north-western Canada 1.7 billion-years ago. This will be helpful to understand the geological evolution of the Canadian Shield, and ultimately, how Earth formed, how it changed through time and how it will evolve in the future. The researchers will be using transportation (helicopter and fixed wing aircraft), logistics and lodging provided by mining companies (Triex Minerals, Cameco Corp.) that are working in the region. They plan to operate during a 3-week period, from mid July until early August 2007. They will be using standard geological field mapping techniques, including ground traversing and collection of small (hand-size) rock specimens for laboratory research. They will also examine and sample pieces of drill core recovered from exploration activities by the mining companies. Rock specimens will be processed to extract minerals used for radiogenic isotope dating. Results will be presented at meetings of learned societies, such as the Geological Association of Canada (this meeting was held in Yellowknife this year). The researchers will also present results at the N.W.T. Geoscience forum, held every November in Yellowknife. They are also available to meet with any community organizations that would be interested in this research. Fieldwork will be conducted from July 21 to December 31, 2007 within the region bounded by 67°30'N, 66°20'N, 115°00'W and 120°00'W. The study area closely coincides with the Edailla area of interest, northeast of Great Bear Lake.
