Sudbury Basin

The Sudbury Basin in Ontario, Canada, is one of the world's largest and oldest known impact craters, formed about 1.8 billion years ago when a massive asteroid struck Earth. This collision melted rock and created a large, bowl-shaped depression rich in valuable minerals, especially nickel and copper. Over time, geological processes brought these minerals to the surface, making the area a significant mining hub. The basin's unique geology offers important insights into Earth's history and impact events, and it remains a vital economic resource due to its rich mineral deposits.
