The Gulikujin (silver) deposit is a iced feldspar-sericite type and its output is related to central volcanic eruptions in the mid-Yanshan “decompression-shear” environment. The deposit (body) is affected by volcanic domes and breccia breccia North-East and North-East faults. The ore-bearing rocks are the Cretaceous Changle Formation, Guanghua Formation Andesite, Dacite and Neoproterozoic-Lower Cambrian Sima Lake Ml. Quality schists and gneisses. The ore deposits are divided into three types of mineralization (Au type, Au-Ag type and Ag type) and veins And network veins. The alteration of wall rocks mainly includes silicification, ice feldspathization, sericitization, dolomitization and pyrite mineralization. Silicification and ice feldspathization are most closely related to mineralization. Mineralization The temperature of 185 ~ 25 5 ℃ and the pressure of metallogenetic formation of 13.5 MPa (average), the salinity of ore-forming solution is 0.56 4% Na Cl (average) and the depth of ore-forming is 500 ~ 600 m. The role, genesis and metallogenic model have also been explored and elaborated.
