ADAMITE on LIMONITE (small cabinet)

Adamite is a mineral composed of zinc arsenate hydroxide, with the chemical formula Zn2AsO4OH. It is commonly found in the oxidized or weathered areas. 

Found above zinc ore deposits. While pure adamite is colorless, it often appears yellow due to the presence of iron compounds. Additionally, green hues can be observed, which are attributed to copper substitutions within its structure.

Limonite is an iron ore composed of a blend of hydrated iron(III) oxide-hydroxides with varying compositions. It is commonly represented by the formula FeO(OH)·nH2O, though this representation may not fully capture the variability in the oxide to hydroxide ratio. Limonite ranks among the three main iron ores, alongside hematite and magnetite, and has been extracted for iron production since at least 400 BC.
