Abstract: According to the section of siliceous rock construction in Qiaerlong, Xinjiang, the paper analyzed the main rock, sedimentary environment, mineralization characteristics. It is considered that its paleogeographic environment is the neritic-bathyal basin, the silicon origins from the volcano source or the associated submarine exhalation. In the construction, the fine granodiorite porphyry intruded into deposit contains especially abundant Ag, Pb and Zn elements, which are enriched and mineralized in local zone. The research provides the prospecting direction for seeking polymetallic silver, lead and zinc deposit in this area.
