  • Chapter 5 - Precambrian Basement

    The Precambrian basement is poorly known under deeper, and several shallower, parts of the basin. However, some of the shallower portions, particularly in northern Manitoba, have been actively explored by mining companies. Well over 2500 diamond-drill holes have penetrated the Precambrian under WCSB cover in northern Manitoba.

    Many large meteorite impact structures throughout the world host mineral resources that are either currently mined or have the potential to become important economic resources in the future. The giant Vredefort-Witwatersrand and Sudbury impact structures underline this statement, because of their enormous resources in gold and uranium, and nickel, copper, and PGEs, respectively. In relation to ...
