Nezhilovite is a magnetoplumbite mineral discovered in 1996 by Bermanec et al.,[1] who gave it the ideal elemental formula PbZn2(Mn4+, Ti4+)2Fe8O19. It forms black magnetic crystals up to 1mm with a tabular, hexagonal outline.[2] The mineral is optically anisotropic, bireflectant and is paramagnetic.[2] The minerals occurs in a matrix of "pink from a Precambrian metamorphic complex of gneisses, schists and marbles in the area" of the .[2]
