It is one of the largest areas of Precambrian rock on Earth, stretching from the Atlantic Ocean to the Pacific Ocean and from the Arctic Ocean to the United States border. This geological formation is not only significant for its size but also for the diverse types of rock that compose it, which have shaped the landscape and influenced the region’s natural resources and climate. In this article, we will explore the various rock types that make up the Canadian Shield and their geological significance.
