Melanterite
Melanterite is a hydrous iron sulfate mineral with the chemical formula iron(II) sulfate heptahydrate. It crystallizes in the monoclinic system and is characterized by its softness, with a Mohs hardness of 2. The mineral typically exhibits a white streak and a vitreous to dull luster. It is usually found in shades of blue to dark green, though it may appear colorless when pure. Melanterite belongs to the sulfate mineral class and is classified under the Strunz system as 7.CB.35. It is commonly associated with the oxidation zones of sulfide-rich ore deposits and is known for its instability, often dehydrating upon exposure to air.

Overview
Melanterite is a hydrous iron sulfate mineral with the chemical formula iron(II) sulfate heptahydrate.

Etymology
The name 'melanterite' is derived from the Greek words 'melas' meaning black and 'hner' meaning dew, referring to the dark color and deliquescent nature of the mineral. It is not named after a person or place but rather after its chemical composition as ferrous sulfate heptahydrate.
Geological genesis
Melanterite typically forms in the oxidation zones of sulfide-rich ore deposits, where it results from the weathering of primary sulfide minerals such as pyrite. It is a secondary mineral that develops in low-temperature environments and is commonly associated with other hydrated sulfate minerals.
