Nezhilovite is a magnetoplumbite mineral discovered in 1996 by Bermanec et al., [1] who gave it the ideal elemental formula Pb Zn2( Mn4+, Ti4+)2 Fe8 O19. 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 dolomitic marble from a Precambrian metamorphic complex of gneisses, schists and marbles in the Nezhilovo area" of the Pelagonian massif. [2]
