description Atacamite Overview
Atacamite is a copper chloride hydroxide mineral with the chemical formula Cu2Cl(OH)3. It commonly forms green crystals or granular coatings in the oxidized zones of copper deposits, especially in dry environments where copper minerals react with chloride-bearing fluids. Its vivid green color and copper content make it of interest to mineral collectors and to geologists studying secondary ore minerals.
help Atacamite FAQ
What is the chemical formula of atacamite?
