Fülöppite, Pb3Sb8S15, is a rare mineral which was originally described from Baia Mare in Romania. It is one of a group of monoclinic lead-antimony sulphosalts with the general formula Pb3+2nSb8S15+2n (Gaines et al., 1997). Fülöppite was first reported in Britain from Wet Swine Gill, Caldbeck Fells, Cumbria (Fortey et al., 1984). It was described as dark grey metallic patches of fibrous crystals accompanying stibnite. More recently, rare dark red resinous to submetallic subhedral to euhedral crystals associated with Journal of the Russell Society (2005) stibnite were identified as being close to fülöppite by XRD (Neall and Green, 2001). The composition of these crystals has been determined by wavelength dispersive X-ray spectroscopy and is the subject of this note.
