Geochemical Anomaly Characteristics And Prospecting Prospect In The Wangguantun Area,northern Shanxi Province

Wangguantun area is located in the important Yanggaowangguantun polymetallic metallogenic belt in Shanxi Province.In order to further study the prospecting prospect of Wangguantun area,1:50,000 stream sediment geochemical survey was carried out in the study area.With the title of "Geochemical anomaly characteristics and prospecting prospect in Wangguantun area,North Shanxi Province",this paper calculates and analyzes the parameter characteristics of each element through the statistics of geochemical data,and delineates the element combination anomaly and comprehensive anomaly in the study area.In this paper,the geochemical anomaly characteristics of the study area are explained and evaluated.Combined with the metallogenic geological background,the metallogenic potential area and prospecting target area are delineated,and the prospecting indicators and prospects in the area are analyzed.The results show that Pb,Au,Bi,W,Mo and Ag are the key prospecting elements in the area.Late Jurassic rocks,dikes and middle Triassic magmatic rocks are the main ore-bearing geological bodies in the area.The limonite,silicification and lead mineralization zones in the study area are significant,which is an important indicator of prospecting in this area.Seven geochemical comprehensive anomalies have been delineated.The abnormal element combinations of ASI-1 are Pb,Zn,Ag,Sb,W,As,ASI-2 are Pb,Ag,As,Sb,Cd,Zn,W,and ASI-3 are Pb,Ag,Zn,Bi,Cu,Au.ASI-4 type B combination of abnormal elements are Pb,Ag,Bi,As,Hg,Cu,Au,ASI-5 type B combination of abnormal elements are Au,Cu,Hg,ASI-6 type B combination of abnormal elements are Au,Ag,Cu,Zn,W.The element combinations of ASI-7 type B are Au,Ag,Cu,Zn and Bi.Combined with the distribution law of comprehensive anomalies and metallogenic geological conditions,the Yulinkou Pb type B metallogenic prospect area is delineated,and the key prospecting target area of Y1 is screened out.Among them,ASI-1 and ASI-2 comprehensive anomalies have the best metallogenic prospect and have the potential to search for lead and other polymetallic deposits.
