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 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 ...
The geology of Saskatchewan can be divided into two main geological regions, the Pre-Cambrian or Canadian shield and the Phanerozoic or Western Canada Sedimentary Basin. Within the Canadian shield exists the Athabasca sedimentary basin. Meteorite impacts have altered the natural geological formation processes.
This is an area of rolling hills with lakes both small and large, wetlands, and rocky outcrops on the Canadian Shield in northern Saskatchewan, north-central Manitoba (north and east of Lake Winnipeg) and Northwestern Ontario.
The Churchill Craton is the northwest section of the Canadian Shield and stretches from southern Saskatchewan and Alberta to northern Nunavut. It has a very complex geological history punctuated by at least seven distinct regional tectono metamorphic intervals, including many discrete accretionary magmatic events.
Carswell is an impact structure within the Athabasca Basin of the Canadian Shield in northern Saskatchewan, Canada. [1] It is 39 kilometres (24 mi) in diameter and the age is estimated to be 115 ± 10 million years (Lower Cretaceous). The impact structure is exposed at the surface. Landsat image with crater structure overlain.
The Boreal Shield Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is the largest ecozone in Canada. Covering 1.8 million square kilometres it covers almost 20% of Canada's landmass, stretching from northern Saskatchewan to Newfoundland .
The Kazan Region is a physiographic province of Canada and the part of the Canadian Shield that is located in extreme northeastern Alberta, northern Manitoba, and Saskatchewan, and also in parts of the Northwest Territories and Nunavut. [1]
