Adamite

Adamite, classified as a zinc arsenate hydroxide mineral, typically appears in the oxidized or weathered zone above zinc ore deposits. While pure adamite is colorless, it often exhibits a yellow hue, with occasional tints of green attributed to copper substitutions in its mineral structure.

This mineral serves as a secondary component in the oxidized zone of zinc- and arsenic-containing hydrothermal mineral deposits. Its presence is commonly associated with minerals such as scorodite, smithsonite, hemimorphite, olivenite, quartz, calcite, and iron and manganese oxides.

Mineral collectors favor adamite for its yellow to bright lime-green colored crystals and druze, coupled with its distinctive fluorescence.
