Nezhilovite

Nezhilovite is a magnetoplumbite mineral discovered in 1996 by Bermanec et al., who gave it the ideal elemental formula PbZn2(Mn4+, Ti4+)2Fe8O19. It forms black magnetic crystals up to 1mm with a tabular, hexagonal outline. The mineral is optically anisotropic, bireflectant and is paramagnetic. 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.
