Abstract: The Jinding lead-zinc deposit is located in the northern of the Lanping-Simao Basin in western Yunnan, which is a world-class super large lead-zinc deposit.The electron probe microanalysis (EPMA)technology was used to determine the trace element composition of pyrite and sphalerite in different ore sections of the Jinding lead-zinc deposit in this paper (Beichang, Paomaping and Baicaoping).This paper discusses the geochemical characteristics of metal sulfide and the metallogenic environment of the deposit, which provide a basis for the genesis of the deposit in the study area.The results show that the different host rocks in each ore section are relatively enriched in Pb, Zn and Co, but poor in trace elements, such as Cu, Cd, Ni, Sb and Te, while sphalerite is relatively enriched in Cd and Pb, but poor in trace elements, such as Fe, Mn, Ag, Cu and Sb.Trace elements, such as Cd, Fe, Mn, Ni, Sb, Cu, Pb, Co and Zn, could occur in sulfides as isomorphism, mineral inclusions or various forms.The characteristics of trace elements of sulfides show that there are mainly formed at medium and low temperature.The mineralization temperature shows rising characteristics from Baicaoping to Beichang to Paomaping, which has the characteristics of basin brine.According to the geological and trace element characteristics of the deposit, Jinding lead-zinc deposit should belong to MVT deposit.
