ResumoAbstract Nikischerite, ideally NaFe2+ 6Al3(SO4)2(OH)18(H2O)12, occurs as dark yellow-green micaceous plates to 4 mm, forming radiating balls and aggregates (Huminicki et al. 2003). The mineral has a dull to greasy luster, a pale grayish streak, and a Mohs hardness of 2. It has a perfect cleavage parallel to {001}, which is also the dominant form displayed by the platy crystals. The type locality is the Huanuni tin mine, Dalence Province, Oruro Department, Bolivia, where nikischerite occurs in and on a clay matrix, associated with minor pyrite, pyrrhotite, siderite, and cronstedtite.
