Natrojarosite
Natrojarosite is a sodium-iron sulfate hydroxide mineral with the chemical formula NaFe^3⁺3(SO4)2(OH)6. It crystallizes in the trigonal crystal system and is classified in the Strunz system as 7.BC.10. This mineral is a member of the jarosite group, which consists of hydrous sulfates of trivalent metals. Natrojarosite typically exhibits a yellow to brown color, a vitreous to dull luster, and a relatively low hardness on the Mohs scale. It has a moderate density and is commonly found in oxidized zones of sulfide-rich environments. Its physical properties are consistent with other members of the jarosite group, which are typically secondary minerals formed under oxidizing conditions.

Overview
Natrojarosite is a sodium-iron sulfate hydroxide mineral with the chemical formula NaFe^3⁺3(SO4)2(OH)6. It crystallizes in the trigonal crystal system and is classified in the Strunz system as 7.BC.10. This mineral is a member of the jarosite group, which consists of hydrous sulfates of trivalent metals. Natrojarosite typically exhibits a yellow to brown color, a vitreous to dull luster, and a relatively low hardness on the Mohs scale. It has a moderate density and is commonly found in oxidized zones of sulfide-rich environments. Its physical properties are consistent with other members of the jarosite group, which are typically secondary minerals formed under oxidizing conditions.
Etymology
The name natrojarosite is derived from the Greek word 'natrios,' meaning 'sodium,' in reference to the presence of sodium in its chemical composition.
Geological genesis
Natrojarosite is a secondary mineral that typically forms in oxidized zones of sulfide deposits. As a member of the jarosite group, it is commonly associated with weathering and supergene processes, where iron and sulfate ions are mobilized and precipitate under oxidizing and acidic conditions.
