Cu2Cl(OH)3
heart IMA grandfathered

Botallackite is a rare copper chloride hydroxide mineral with the chemical formula copper(II) hydroxychloride. It belongs to the monoclinic crystal system and is classified as a hydroxide mineral in the Strunz classification system under category 3.DA.10b. The mineral typically exhibits a dull to earthy luster, a greenish or bluish-green color, and a relatively low hardness of 2.5 to 3 on the Mohs scale. It has a low to moderate density and is commonly found as fine, fibrous or botryoidal aggregates. Botallackite is part of the broader group of secondary copper minerals formed through the oxidation of primary sulfide ores.

Overview

Botallackite is a rare copper chloride hydroxide mineral with the chemical formula copper(II) hydroxychloride. It belongs to the monoclinic crystal system and is classified as a hydroxide mineral in the Strunz classification system under category 3.DA.10b. The mineral typically exhibits a dull to earthy luster, a greenish or bluish-green color, and a relatively low hardness of 2.5 to 3 on the Mohs scale. It has a low to moderate density and is commonly found as fine, fibrous or botryoidal aggregates. Botallackite is part of the broader group of secondary copper minerals formed through the oxidation of primary sulfide ores.

Etymology

Botallackite is named after the Botallack mine in Cornwall, England, where it was first discovered. The name reflects its type locality and is not associated with any person or specific discovery date.

Geological genesis

Botallackite is a secondary mineral that forms through the oxidation and weathering of primary copper sulfide minerals in the upper parts of copper ore deposits. It is typically associated with other secondary copper minerals and develops in low-temperature, surface or near-surface environments.

Occurrence

Botallackite is found in the oxidized zones of copper deposits, particularly in the Botallack mine in Cornwall, England, which is its type locality. It is a rare mineral and is not widely distributed globally.
