Rozenite

Rozenite is an uncommon hydrous iron sulfate mineral, Fe²⁺SO₄•4(H₂O).

It occurs as a secondary mineral, formed under low humidity at less than 21 °C as an alteration of copper-free melanterite which is a post mine alteration product of pyrite or marcasite. It also occurs in lacustrine sediments and coal seams. Associated minerals include melanterite, epsomite, jarosite, gypsum, sulfur, pyrite, marcasite and limonite.[1]

It was first described in 1960 for an occurrence on Ornak Mountain, Western Tatra Mountains, Małopolskie, Poland. It was named for Polish mineralogist Zygmunt Rozen (1874–1936).[1][2]
