| Abstract: | Zn-tennantite is a rare mineral discovered in a skarn lead-zinc deposit in Inner Mongolia. The associated minerals include chaleopyrite, sphalerite and galena. Zn-tennantite occurs as xenomorphic granular aggregates 0.2-0.5mm in diameter. It is lead grey in color, H_(VRN)=339-388 kg/mm~2.Under microscope reflection color is greyish blue with a faint greenish tint.Electron microprobe analysis gives S 25.94, As 10.70, Cu 39.67, Zn 7.36, Sb 9.81, Bi 5.81,Ag 0.18 and Fe 0.37. The calculated chemical formula is (Cu_(10.02) Ag_(0.03))_(10.05) (Zn_(1.81)Fe_(0.11))_(1.92)(As_(2.29)Sb_(1.29)Bi_(0.45))_(4.03)S_(13), quite similar to the ideal formula (Cu, Ag)_(10) (Zn, Fe)_2 (Sb, As)_4S_(13).The x-ray powder pattern of Zn-Tennantite is identical with that of tetrahedrite. Unit cell parameter a_0=10.322(). The strongest lines in the powder diffraction pattern are 2.98(), 1.82()and 1.56().It is smaller than tetrahedrite. |
