The geology of Ontario consists of the study of the rock formations in the most populated province of Canada. Ontario has some of the oldest rocks on Earth. It is made up of ancient Precambrian igneous and metamorphic rock and overlain by younger sedimentary rocks and soils. About 61% of the province is covered by the Canadian Shield. The shield can further be divided into three sections or provinces. The northwestern parts of the Shield, located roughly north and west of Sudbury, are known as the Superior province is the largest of the three sections, covering about 70% of the Shield portion in Ontario. The Southern province is a narrow region from Sault Ste. Marie to Kirkland Lake. The South central part is dominated by the Grenville Province but flanked by two basins of Phanerozoic materials. World-class mineral deposits can be found here and are mined extensively.
