It occurs with limonite, malachite, beudantite, adamite, cuproadamite, olivenite and smithsonite. It is also a common form of goethite, smithsonite, fluorite and malachite. It occurs in association with hemimorphite, smithsonite, chrysocolla, coronadite and various iron oxides. It occurs in association with chalcocite, bornite, willemite, smithsonite, hydrozincite, hemimorphite, adamite, olivenite and gebhardite. Associated minerals include azurite, calcite, malachite, and smithsonite. Some associated minerals include&colon; calcite, galena, pyromorphite, smithsonite, vanadinite, and wulfenite. They were made of the zinc carbonates hydrozincite and smithsonite. It occurs associated with smithsonite, hemimorphite, willemite, cerussite, aurichalcite, calcite and limonite. The Kelly Mine produced lead, silver, zinc and smithsonite until the markets collapsed. This deposit consists of cerussite (lead carbonate) and smithsonite (zinc carbonate) ores. Associated minerals include&colon; rosasite, smithsonite, hemimorphite, hydrozincite, malachite and azurite. Associated minerals include azurite, smithsonite, malachite, cerussite, mimetite, wulfenite and olivenite. The oldest known pills were made of the zinc carbonates hydrozincite and smithsonite. Sphalerite ZnS (primary) alters to secondary hemimorphite ZnSiO(OH).HO, smithsonite ZnCO and manganese-bearing willemite ZnSiO. In upper levels, the ore minerals are oxidized to cerussite, anglesite, and smithsonite.
