Minerals are found in different types of rocks. Metallic minerals are usually found in igneous and metamorphic rocks that form large plateaus.

Examples: iron ore is found in north Sweden, copper, and nickel in Canada. In igneous and metamorphic rocks in South Africa, iron, nickel, chromites, and platinum are found. Non-metallic minerals are found in sedimentary rock formations. Limestone deposits are found in France. Mineral fuels such as coal and petroleum are found in sedimentary strata.
