Geochemical Characteristics Of Exploration And Metallogenic Prospect Prediction In Ruoqiang Baishan Area,Xinjiang

The study area is located in the Ruoqiang baishan area of Xinjiang,in the northeast of Tarim Plate and the passive continental margin belt of the northern margin of Dunhuang Landmass.It is located in the core of Beishan Paleozoic rift belt formed by splitting on the metamorphic basement of Paleoproterozoic,specifically in Bijiashan-Hongliuyuan Late Devonian-Permian period intraplate rift zone.The study area belongs to an unmanned area with a low degree of research and Geochemistry is basically in a blank state,It can more effectively and intuitively reflect the role and significance of soil geochemistry survey in the study area.According to the anomalous characteristics of elements in the soil of the study area,the following conclusions can be drawn:the number of anomalous elements of Cu?Co,Mo and W in the soil of the study area is larger,and the number of anomalous elements of Cu,Ni,Co,Cr,As and Sb can reach more than 50.The anomalous scale of elements of As is larger,and the concentration of As reaches three-level zoningThe R cluster analysis and correlation analysis of 15 metallogenic elements in the study area show that the four metallogenic elements of Cu,Ni,Co and Cr in the study area belong to one category and have good correlation,reflecting the element association related to basic-ultrabasic rocks,and Sb belong to one category with good correlation,reflecting the combination characteristics of low-temperature hydrothermal elements.Cu,Ni,Co and Cr are important elements in the study area.Combined with the results of element anomaly and element analysis,and the geological conditions of the study area,three comprehensive anomalies were delineated in the study area:Hy-4 comprehensive anomaly dominated by Cu,Ni,Co and Cr,Hy-11 comprehensive anomaly dominated by Cu,Ni,Cr and Au,and Hy-3 comprehensive anomaly dominated by Mn,Ni,Co,Au and Cr.The three comprehensive anomalies were explained and evaluatedStarting from the geochemical characteristics of soil,this paper discusses the distribution characteristics of elements,studies the R cluster analysis and correlation analysis of elements,analyses the characteristics of multi-element combination,interprets and infers the comprehensive anomaly area combined with the regional geological background,regional magnetic anomaly,gravity anomaly and anomaly verification results,and delineated three ore prospect areas.It has important theoretical and practical significance for guiding the next prospecting in Ruoqiang Baishan area.
