The ore deposits in Sudbury are part of a large geological structure known as the Sudbury Basin, believed to be the remnants of a 1.85-billion year old meteorite impact crater. Sudbury ore contains profitable amounts of many elements, especially transition metals, including platinum. It also contains an unusually high concentration of sulfur. When nickel-copper ore is smelted, this sulfur is released into the environment, where it is toxic to vegetation. Carried aloft, it combines with atmospheric water to form sulfuric acid. This contaminates atmospheric water, resulting in a phenomenon known as acid rain.
