Zaccagnaite

Zaccagnaite is a mineral, with a formula Zn₄Al₂CO₃(OH)₁₂·3H₂O. It occurs as white hexagonal crystals associated with calcite in cavites in Carrara marble of the Italian Alps and is thought to have formed by hydrothermal alteration of sphalerite in an aluminium rich environment. It is named after (1851–1940), an Italian mineral collector.
