Abstract
Abstract The second world known occurrence of magnetoplumbite is described in dolomitic marbles from Nezilovo (Macedonia). According to electron microprobe analyses and thermogravimetric data the chemical formula is (Pbo.99Cao.o1)(Fe6.12Mn2.53Zn1.89Al1.o3Tio.41Mgo.o2) (O17.78OH0.94); this magnetoplumbite is therefore a Zn-rich variety. The cell dimensions refined from X-ray powder diffraction data are: a = 5.854(1) Å and c = 22.882(6) Å.
