    Bedrock geological map of Canada 1:5 000 000

    The map displays bedrock formations at or near the surface of the land, on the sea floor above the continental crust that forms the Canadian landmass, and oceanic crust surrounding the landmass. The bedrock units are grouped and coloured according to geological age and composition. The colours of...

    BIGMAC87 refraction; 3 refraction profiles; seismic refraction

    In 1987 the Geological Survey of Canada undertook a major regional seismic refraction survey in the Mackenzie Delta and surrounding area in order to complement existing data with information on the velocity structure of the crust and upper mantle. The survey consisted of seven recorder...

    Melville MT; 30 MT sites; 2D seismic reflection

    As part of a multidisciplinary geoscience project, the conductivity structure of the lithosphere beneath the Melville Peninsula, Nunavut, has been imaged using magnetotelluric methods. The data reveal near-vertical, less resistive features that extend through the crust and correlate with surface...

    East Arm Teleseismic; Station EA06; teleseismic

    Ten teleseismic stations were installed in 2008 in a linear array crossing Artillery Lake. Data can be used for SKS-anisotropy studies that reveal structural fabrics within the mantle or are suitable for discontinuity studies that can detect large-scale layering within the mantle.
