Why is Sudbury so rich in minerals?
The asteroid impact that created it 65 million years ago is largely credited for the mass extinction of the dinosaurs. In Sudbury, the giant pool of molten rock eventually hardened and concentrated the minerals that have made the region one of the most productive mining jurisdictions in the world.

Reports published in the late 1960s described geological features that were said to be distinctive of meteorite impact, including shatter cones and shock-deformed quartz crystals in the underlying rock. Geologists reached consensus by about 1970 that the Sudbury basin was formed by a meteorite impact.
