The province of Manitoba sits partially on the Canadian Shield (Precambrian Shield) and the Interior Plains (including the sedimentary basins), regions of Canada. The oldest geology of Manitoba is associated with the Precambrian shield, including crystalline rocks dating back more than 1.5 billion years. This is where the majority of the metallic mineral deposits can be found in Manitoba. The sedimentary basin dates to the Phanerozoic period, which dates back to less than 500 million years.
