It occurs in association with hemimorphite, smithsonite, chrysocolla, coronadite and various iron oxides. It occurs associated with smithsonite, hemimorphite, willemite, cerussite, aurichalcite, calcite and limonite. Associated minerals include&colon; rosasite, smithsonite, hemimorphite, hydrozincite, malachite and azurite. The main ore minerals include sphalerite, galena, and hemimorphite. It commonly occurs in association with hemimorphite, willemite, hydrozincite, cerussite, malachite, azurite, aurichalcite and anglesite. Two minerals, zincite and hemimorphite, have been historically called calamine. The Wenshan Zinc Mine is known for producing world class, deep blue hemimorphite specimens. Sphalerite ZnS (primary) alters to secondary hemimorphite ZnSiO(OH).HO, smithsonite ZnCO and manganese-bearing willemite ZnSiO.
