摘　　要：架上钨钼普查区位于赣东北地区,区域上具有良好的钨钼矿成矿地质条件。为了分析矿区成矿地质及地球化学条件,根据1∶1万土壤地球化学测量结果,运用相关分析和因子分析等方法,显示W、Mo、Bi、Cu、Ag元素相对富集成矿的可能性较高,通过迭代方法,计算10种元素的背景值和异常下限值,共圈定单元素异常219个,其中Au异常12个,Ag异常30个,Mo异常12个,Cu异常25个,Pb异常35个,Zn异常23个,W异常20个,Sn异常20个,Bi异常22个,As异常20个。结合成矿地质条件及各元素异常特征,圈出找矿靶区2处,其中Ⅰ级靶区1处(Ⅰ甲),Ⅱ级靶区1处(Ⅱ甲)。The Jiashang tungsten molybdenum mineral survey region is located in Northeastern Jiangxi Province,There are good geological conditions for the mineralization of tungsten and molybdenum deposits in the region.In order to analyze the metallogenic geological and geochemical conditions of mineralization in the mining area,based on the results of 1∶10000 soil geochemical survey,the authors concluded that W,Mo,Bi,Cu,Ag has better positive relevance than other elements.Through the iterative method,the background values and anomalous lower limits of the 10 elements are calculated,and 219 single-element anomalies have been identified,of which 12 are Au anomalies,30 are Ag anomalies,12 are Mo anomalies,25 are Cu anomalies,35 are Pb anomalies.There are a total of 219 single-element anomalies,including 12 Au anomalies,30 Ag anomalies,12 Mo anomalies,25 Cu anomalies,35 Pb anomalies,23 Zn anomalies,20 W anomalies,20 Sn anomalies,22 Bi anomalies and 20 As anomalies.Combined with the geological conditions of mineralization and the anomalous characteristics of each element,we have circled 2 mineral searching target areas,including 1 levelⅠtarget area(ⅠA)and 1 levelⅡtarget area(ⅡA).
