The Metallogenic Regularity And Prospecting Direction Of Silver Polymetallic Ore Deposit In Chengde Cluster

With the increasing exploration efforts and the prospecting breakthrough in recent years, Chengde cluster have great prospecting potential in the silver polymetallic ore. Based on regional geology, geochemistry, geophysics and regional mineral characteristics, features of the ore, silver polymetallic timely summary of research in the area of mineralization, metallogenic chronology, tectonic environment, set up a metallogenic model and prospecting model, in order to guide the prospecting work, has important scientific significance.Large silver polymetallic deposit in Chengde cluster as the main object of study, through the anatomical study on two typical silver ring,Niujuan?Guzigou polymetallic deposit,metallogenic regularity and formation mechanism of the understanding of the types of ore deposits. Conclusion Chengde cluster silver polymetallic deposit in Yanshan district was related with acid rock, ore belongs to the crust mantle mixed source. Structures in the area along theregional overall most silver polymetallic deposit-magmatic belt production, construction is an important condition for the formation of ore deposits of this type and distribution, can not only provide the diagenetic and metallogenic conditions, ore also provide environment for ore fluidand the occurrence of precipitation, and even affect the preservation and transformation ofthe environment. In silver polymetallic deposit is mainly produced in the HONGQIYINGZI groupmetamorphic rocks as the volcano rock basin basement or at the edge of. Chengde cluster most silver polymetallic deposit are produced in the volcano rock in the basin and the Proterozoic strata in the contact zone of fault basin, volcano in fault as the boundary, is conducive to the volcano intrusive hydrothermal fluid migration and precipitation,silver polymetallic deposit are often produced in the volcano graben basin side.Based on the summary of Chengde cluster of silver polymetallic deposit,summarized the regional metallogenic model, lay the foundation for further understanding themetallogenic mechanism and ore deposit; metallogenic laws and determine the prospecting marks for the mining area to achieve a major breakthrough in prospecting for new ideas and clues.
