Sudbury Basin
Canadian mining region
Sudbury Basin is a geological structure in Ontario, Canada, formed by a meteorite impact roughly 1.85 billion years ago.
One of the largest and oldest impact craters on Earth, it spans about 60 kilometers.
The basin contains rich deposits of nickel, copper, and platinum-group metals, making Sudbury one of the world's major mining centers: The mines in the Sudbury Basin produce much of the world's nickel supply.
