Description
An uncommon mineral composed of dibasic copper sulfate. Antlerite is an emerald green to blackish-green color and is found in the oxidized zones of copper deposits of Arizona and Chile. It has also been identified as a corrosion product on outdoor bronze and copper sculpture. Though similar in color to Malachite and Brochantite, antlerite does not effervesce in contact with acid.
