It is area which composed by igneous rock which relates to its long volcanic history. It spans Eastern, Northeastern, and East-central Canada and the Northern portion of the upper Midwestern United States. The population of human here is rare and the industrial development is minimal.

Facts about Canadian Shield 2: Greatest Area
The Canadian Shield is the part of North America. It becomes the Earth’s greatest area of exposed Archean rock. The metamorphic base rocks are mostly from Precambrian Era.
Facts about Canadian Shield 3 :Geology
It becomes the oldest on the earth, approximately 2.5-3.5 billion years. The area was originally very large mountains. It has 12,000 metres or 39,000 feet with volcanic activity. It has some the oldest volcanoes on the planet. It also has 150 volcanic belts.

Facts about Canadian Shield 9: Mountain Expose
This mountain has deep roots and float on the denser mantle like an iceberg at sea. Like mountain erodes, its roots rise are eroded. Although, this mountain has ever been exposed, many areas ar still exist.
Facts about Canadian Shield 10: Diamond’s Discovery
The Shield, particularly the Northwest Territories has been the site of several major of diamond discoveries. The kimbrlite eruptions bring the diamond from over 150 kilometres (93 mi) depth to the surface.
Those are the facts about Canadian Shield. There are many interesting facts. Hope those points give much informations that give benefit for all people.
