Rozenite
Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters". Rozenite is a hydrous iron sulfate mineral, Fe2+SO4·4(H2O).
It occurs as a secondary mineral, formed under low humidity at less than Script error: No such module "convert". 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]
The thermal expansion of rozenite was studied from Script error: No such module "convert". to Script error: No such module "convert". using neutron diffraction. Rozenite exhibits negative linear thermal expansion, meaning that it expands in one direction upon cooling.[3]
