Mineralogy and Geochemistry of Tellurides, Selenides and Sulfides from the Zhaishang Gold Deposit, Western Qinling, China: Implications for Metallogenic Processes

•The independent selenides coexisting with tellurides and sulfides were discovered for the first time in the Zhaishang gold deposit.•The ore-forming materials leached from the underlying Paleozoic strata, and were affected by Indosinian magmatism.•The mineral paragenetic association shows that the redox conditions have changed from reduction to oxidation during the fluid evolution process.•The sulfur, tellurium and selenium fugacity of hydrothermal fluid of the main metallogenic stage is estimated in this paper.
