Stannite is a sulfide mineral with complex structure, belonging to the Cu-Sn--Fe-S system. Stannite samples were collected from four places in South China. Electron microprobe analysis was performed for its chemical composition. X-ray diffraction analyses show that its unit cell parameters are a= 5.4531 (5) A and c= 10.7470 (7) A, belonging to tetragonal system with space group 142m. Mossbauer parameters of Sn and Fe in stannite from four different localities indicate that IS values and QS values are respectively1.34-1.49 mm/s and 0.36--0.50 mm/s for Sn, suggesting Sn4+ of tetrahedra,and are respectively 0.588-0.596 mm/s and 2.900-2.911 mm/s for Fe,suggesting Fe2+ of tetrahedra. Sn, Fe cations only occupy one sort of crystal-lographic sites. Stannite from these places are enriched in Zn, which exists in the form of isomorphous replacement of Fe.
