The relative enrichments of Au, trace elements, S, and Fe in gold deposits in the Dian-Qian-Gui area are nearly identical to those of Nevada Carlin-type deposits. Pyrite, marcasite, and arsenopyrite of the ore stage typically occur as disseminations, and locally in open spaces, and have high concentrations of Au, As, Sb, Hg, and Tl, and low Ag and base metals. These elements are soluble in H2S-rich fluids and precipitated by sulfidation of ferroan minerals in the host rocks or Fe in a contrasting fluid. δ34S data indicate reduced S was derived from sedimentary rocks. These data and the absence of subduction-related plutons in the area are consistent with amagmatic models for these deposits.
