| The study area is located in the Beishan Late Paleozoic backarc basin rifting zone,and the structural forms in the area are mainly fold and fault assemblages under compression background.The area is located in the Beishan metallogenic belt of 16 key minerals and metallogenic zones in China,which has good metallogenic geological conditions and abundant mineral resources.Regional typical deposits mainly include 460 large gold deposit,shuangjianshan large gold deposit,langwashan large iron ore deposit,gongbuquan medium copper deposit,Hongjianbingshan medium wolframite deposit,etc.On the basis of collecting previous achievements of 1:200,000 stream sediment survey and1:50,000 rock survey,this paper has achieved the following results mainly through this 1:50,000 soil geochemical survey:(1)based on the 1:50000 soil geochemical data processing,combined with the geochemical background in the study area,various mineral ore-forming geological background,Au,Ag,Cu,Pb,zinc,W,Mo,Bi,Cr,Ni is the main ore-forming elements,including Cr,Ni,Pb,Ag,Cu,zinc,W element dispersion degree is bigger,The possibility of mineralization is large.The variation coefficient of Mo,W,Bi and Au elements is large,which is conducive to mineralization.The superposition coefficient of Cr,Zn,Mo,W and Bi is larger than that of the Beishan background value,especially Mo is the largest,which is very favorable to the mineralization.(2)The 1:50,000 soil geochemical anomalies in the study area were delineated.There were a total of 467 element anomalies,including 17 comprehensive anomalies,including 2 category A 1,1 category A 2,3 category B 2,6 category B 3 and 5 category C 2 anomalies.(3)On the basis of comprehensive research,this paper divides 5 prospecting prospect areas and 12 prospecting target areas,which provides scientific basis for further prospecting work.(4)Through the verification work on the target area,the newly discovered ore(mineralization)point 12,the verification effect is good,has a certain scientific value. |
