The Jinchanghe Pb-Zn polymetallic deposit is a representative distal skarn deposit in the Baoshan block. Due to limited research on the sources of ore-forming metals and trace elemental geochemistry of sulfides, the sources and mineralization environments of the Jinchanghe skarn Pb-Zn polymetallic deposit are still controversial. In this study, copper and …

The ore-forming elements display a vertical sequence along with the trend of orebody V, which can be divided into a lowermost Zn–(Pb + Ag) zone, a central Zn + Pb + Ag–(Sb) zone, and an uppermost Pb + Zn + Ag + Sb zone, without horizontal zoning (Fig. 3; Zhang 2013; Wang et al. 2017, 2018). Additionally, various types of alteration have ...
