Antlerite

Cu23SO4(OH)4
heart IMA approved

Antlerite is a basic copper sulfate hydroxide mineral with the chemical formula Cu3SO4(OH)4. It belongs to the monoclinic crystal system and is classified as a sulfate mineral in the Strunz system (7.BB.15) and as a sulfatite in the Dana classification (30.1.12.1). Antlerite typically exhibits a bright green color and has a vitreous to silky luster. It has a hardness of approximately 3.5–4 on the Mohs scale and a relatively high density of around 3.8 g/cm³. This mineral is commonly found in the oxidation zones of copper deposits and is known for its prismatic or fibrous crystal habit.

Overview

Antlerite is a basic copper sulfate hydroxide mineral with the chemical formula Cu3SO4(OH)4. It belongs to the monoclinic crystal system and is classified as a sulfate mineral in the Strunz system (7.BB.15) and as a sulfatite in the Dana classification (30.1.12.1). Antlerite typically exhibits a bright green color and has a vitreous to silky luster. It has a hardness of approximately 3.5–4 on the Mohs scale and a relatively high density of around 3.8 g/cm³. This mineral is commonly found in the oxidation zones of copper deposits and is known for its prismatic or fibrous crystal habit.

Etymology

Antlerite is named after the Antler Mine, where it was first discovered. The IMA approved the mineral's status, but no specific discovery year is provided in the facts.

Geological genesis

As a sulfate mineral, antlerite typically forms in the oxidation zones of copper sulfide deposits through the weathering of primary copper minerals. It is commonly associated with other secondary copper minerals and forms under low-temperature, surface conditions.

Occurrence

Antlerite is primarily associated with the Antler Mine, which is its type locality. It occurs in oxidized copper deposits, often alongside other secondary copper minerals.

Spiritual meaning and crystal therapy

Spiritual meaning

Antlerite is traditionally associated with spiritual growth and transformation. It is believed to support inner change and encourage a deeper connection with one's higher self.

Esoteric properties

Antlerite is said to promote emotional healing and spiritual awakening. It is associated with enhancing intuition and aiding in the release of negative energies.

Associated chakra

Antlerite is traditionally linked with the heart chakra due to its greenish hue and is believed to support emotional balance and compassion.

Crystal therapy use

In crystal therapy, antlerite is often used in meditation or placed near the heart chakra. It can be worn as jewelry or carried to support emotional healing and spiritual insight.
