Metals | American Geosciences Institute

Metals occur in many different geologic settings around the world. If enough metal is concentrated in one place to be of economic value, it is called an ore deposit. Well-known metals include copper, iron, gold, aluminum, manganese, and platinum, but nearly all of the sixty or so metals in the periodic table have practical uses.
