Very rare. Mainly at outcrop and in the first oxidation zone, but also in the second oxidation zone.
- 1st Oxidation Zone
- 2nd Oxidation Zone
Paragenetic and General Notes
Hydrozincite occurs in a characteristic paragenesis, with aurichalcite and hemimorphite, in the upper portion of the first oxidation zone (Gebhard, 1999).
Hydrozincite is found as white to grey crusts, stains, powdery masses and coatings on smithsonite and, rarely, as efflorescences of minute, tabular crystals (Pinch and Wilson, 1977).
Hydrozincite also occurs in the type assemblage for reinerite, on 29 Level in the second oxidation zone (Geier and Weber, 1958).
