摘　　要：西秦岭多吉塘地区位于印支造山带同德—泽库弧后前陆盆地,同德—泽库印支期、铜、铅、锌、金、钨、铋、锡成矿带,为了快速圈定找矿靶区,明确找矿方向,在研究区开展1∶10 000土壤测量工作。根据与成矿密切相关的Au、Ag、As、W、Sn、Mo、Sb、Bi等11种元素测试结果,分析了该地区元素地球化学特征,确定研究区内W、Au为主成矿元素。结合成矿地质背景,圈定综合异常9个,通过异常检查,发现了多条钨(化)体和金矿化线索,表明该地区具备了良好的成矿地质、地球化学条件,具有钨矿、金矿的找矿潜力。The Duojitang area of the West Qinling Mountains is located in the Tongde-Zekuhind foreland basin of the Indosinian orogenic belt,the Tongde-Zeku-Indosinian metallogenic belt of copper,lead,zinc,gold,tungsten,bismuth and tin.In order to quickly delineate the prospecting target area and clarify the prospecting direction,a soil survey of 1:10000 is carried out in the study area.According to the test results of 11 elements,such as Au,Ag,As,W,Sn,Mo,Sb and Bi,which are closely related to mineralization,the geochemical characteristics of elements in this area are analyzed,and W and Au are determined to be the main ore-forming elements in the study area.Combined with the metallogenic geological background,9 comprehensive anomalies are delineated,and a number of tungsten bodies and gold mineralization clues are found through anomaly inspection,which indicated that this area has good metallogenic geological and geochemical conditions and has the potential for tungsten and gold deposits.
