The Superior Craton is a large, stable section of the Earth's crust located in eastern Canada and parts of the northern United States. It is one of the oldest geological formations, dating back over 2.5 billion years. The craton is primarily composed of ancient igneous and metamorphic rocks, which provide valuable insights into the early history of the Earth. This craton is significant for its rich mineral resources, including gold, nickel, and copper. It also plays a crucial role in understanding tectonic processes and the formation of continents. The Superior Craton is a key area for geological research and exploration, contributing to our knowledge of Earth's evolution.
