Devilline

CaCu4(SO4)2(OH)6·3H2O
Monoclinic heart IMA approved

Devilline is a hydrous copper sulfate hydroxide mineral with the chemical formula calcium tetracopper bis(sulfate) hexahydroxide trihydrate. It crystallizes in the monoclinic system and is classified as a basic copper sulfate mineral. This mineral typically exhibits a vitreous luster and is commonly found in shades of blue or green. It has a relatively low hardness, ranging from 2 to 3 on the Mohs scale, and a specific gravity of approximately 3.3 to 3.6. Devilline is part of the sulfate mineral group and is often associated with secondary copper mineralization.

Overview

Devilline is a hydrous copper sulfate hydroxide mineral with the chemical formula calcium tetracopper bis(sulfate) hexahydroxide trihydrate. It crystallizes in the monoclinic system and is classified as a basic copper sulfate mineral. This mineral typically exhibits a vitreous luster and is commonly found in shades of blue or green. It has a relatively low hardness, ranging from 2 to 3 on the Mohs scale, and a specific gravity of approximately 3.3 to 3.6. Devilline is part of the sulfate mineral group and is often associated with secondary copper mineralization.

Etymology

Devilline is named after Henri Étienne Sainte-Claire Deville, a French chemist known for his work in inorganic chemistry and mineralogy.

Geological genesis

Devilline forms under low-temperature conditions, typically as a secondary mineral in the oxidation zones of copper sulfide deposits. It is commonly associated with the alteration of primary copper minerals and is found in environments where copper-rich solutions interact with sulfate-bearing waters.
