| Résumé | (disponible en anglais seulement)
Over the last 2 million years, great ice sheets have scoured much of Canada, leaving behind a landscape covered with glacial sediments. The thick sediments that
glaciers left behind include metal-rich debris that was eroded and then carried down-ice from mineral deposits -these trails of metal-rich glacial debris are referred to as dispersal trains. The spatial footprint of these dispersal trains are much
larger exploration targets than the actual mineral deposit. The development and use of indicator mineral methods have become an important method to detect these dispersal trains. Canada's first diamond mines were discovered using this method. The
Geological Survey of Canada (NRCan) has been working in collaboration with industry and academia over the past 30 years to expand and improve indicator minerals methods such that they can now be used to explore for a broad range of commodities in
Canada's glaciated landscape, including diamond, rare earth elements, and precious and base metals. |
