Detailed explanation-1: -The Canadian Shield is the ancient core of the North American Continent. It is composed mainly of highly metamorphosed granite, with smaller areas of metamorphosed sedimentary and igneous rocks and some areas of relatively horizontal but still quite ancient sedimentary rocks.
Detailed explanation-2: -It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible.
Detailed explanation-3: -Landforms in the Canadian Shield include both flat areas and rocky hills. There are forests, tundra, and lowlands. More than one quarter of the Canadian Shield’s surface is covered by water. The Canadian Shield has thousands of lakes, rivers, streams, and marshes.
Detailed explanation-4: -This region contains the oldest rocks in Alberta, which are 1.6 to 1.8 billion year old sandstones and conglomerates of the Athabasca Basin and granitic and gneissic rocks of the even older Canadian Shield. Very little is known about groundwater in this region.
