This Open File release includes files containing a 3-dimensional model that encompasses a volume of the Earth down to 300 km in central Nunavut. The region covered is between the northern communities of Baker Lake, Kugaruk, Repulse Bay and Rankin Inlet. Several geophysical data sets and derivative 3-D models have been assembled: these include gravity gradients, P-wave speeds, surface wave speeds, conductivity, and receiver functions. These are geo-registered with the GEM Tri-territorial geological map compilation. The 3-D models and their interpretation provide context and insights into the locations and sources of known diamond and gold deposits in this region as well as into the structure geometries associated with the tectonic construction of this part of the Canadian Shield.
