Medium-sized Au-Ag epithermal vein deposit, occurring along the Yanshannian intra-continental volcanic basin along the southeastern Inner Mongolia-Xinganling Hercynian fold belt. The host rocks are Late Jurassic siliceous, intermediate, and mafic volcanic rocks with a Rb-Sr isochron age of 147.5 Ma. The deposit is controlled by circular and radial faults around a maar volcano that occurs at the intersection between east-west-trending major faults and northwest-trending faults. Wallrocks display silica, carbonate, sericite, and propylitic alterations. Depositional temperatures range from 180 to 240 °C and pressures from 20 MPa to 1.48 MPa.
