Caledonite also known as caledonita is a mineral with an orthorhombic crystal structure. Discovered in 1832 caledonite is rare mineral and is found in the oxidizied zones of copper-lead deposits as a secondary mineral. It can be found in the Leadhills-Wanlockhead District in Scotland. Currently there are no industrial uses for caledonite. Minerals are natural compounds formed through geological processes. ...
