A mineral sequence of scheelite > molybdenite > chalcopyrite was identified. Re–Os and Ar–Ar dating constrained the mineralization to 428–391 Ma. S–Pb–D–O geochemistry suggests metals and fluids sourced from granite and host rocks. Xiaoliugou is a skarn system formed in a mid-Paleozoic continental collision setting.
