Pangkaimen gold-silver deposit located at Aihui-Huma metallogenic belt, and the ore body mainly hosted in volcanic rocks of the Ganhe formation of Jurassic.The ore body was formed with veins and distinctly controlled by fault structure.Many fault structures occurred in the study area, and were classified into five trending directions of NEE,NNE,NNW,NWW and NS.There are mainly four tectonic epochs in the study area and the tectonic directions are NEE,NNE,NNW and NWW in time order.The fault structure in NEE direction showed inherited activities,and provided a great channel for Yanshanian volcanic eruptions and deep ore-bearing hydrothermal.The extrusion fracture in NNE direction controlled the distribution of the mineralized belt in the study area.The tenso faults in NNW provided large space for precipitation and enrichment of ore-bearing hydrothermal.
