The Canadian Shield is a collage of Archean plates and accreted juvenile arc terranes and sedimentary basins of the Proterozoic Eon that were progressively amalgamated during the interval 2.45–1.24 Ga, with the most substantial growth period occurring during the Trans-Hudson orogeny, between c. 1.90–1.80 Ga. [5] The Canadian Shield was the ...
Pukaskwa National Park in Ontario.. These hills support a large area of rich taiga forest dominated by black spruce (Picea mariana) along with jack pine and some paper birch (Betula papyrifera) and in the warmer south-facing areas some trembling aspen (Populus tremuloides), white spruce (Picea glauca), Ontario balsam poplar (Populus balsamifera) and balsam fir (Abies balsamea).
While the coastal areas are primarily in the Hudson Plains, the northeastern coast bordering Quebec is in the Taiga Shield ecozone. This rocky and hilly eastern shore forms the western edge of the Canadian Shield in Quebec and as such, the main habitat is boreal forest of the Eastern Canadian Shield taiga ecoregion.
Canadian Shield. The Canadian Shield, Precambrian shield, makes up the bedrock geology highlighted by rocks and lakes [2] and a boreal forest area. There are transitional areas between boreal and tundra flora. [3] The lower boundary of the Canadian Shield cuts across the province diagonally from the latitude 57 degrees in the northwest to 54 ...
The Southern Province is a portion of Proterozoic rock that ranges in age from 2.5 billion to 600 million years old. It represents a subdivision of the much larger Canadian Shield and forms the bedrock of portions of Ontario, Canada and the U.S. states of Michigan and Minnesota.
The basin is located on the Canadian Shield in the city of Greater Sudbury, Ontario.
