Other names for the Canadian Shield
include the Precambrian Shield and the Laurentian Plateau. It is made
of primarily of granite and covers 1.7 million square miles. In addition
to granite, it contains deposits of iron, gold, silver, uranium,
platinum, nickel and copper. Diamonds are also found in the Canadian
Shield and are mined in Canada's Northwest Territories. Some of the
world's oldest-known fossils lie in the Canadian Shield; fossil bacteria
and algae in the region date back about 2.2 billion years.
Four mountain ranges rise from the Canadian Shield: the Adirondack
Mountains and Superior Highlands in the United States and the Laurentian
and Torngat Mountains in Canada. The current topography of the Canadian
Shield dates back to the movement of glaciers during the most recent
ice age, and it varies from 1,000 to 5,000 feet above sea level. The
highest points of the Canadian Shield are on Baffin Island and in
northern Labrador.
