摘　　要：湖南省祁东县大路边矿区位于南岭成矿带关帝庙—大义山钨锡铅锌找矿远景区上,该区域成矿条件优越,是寻找钨锡铅锌金属矿的有利地区。为在大路边矿区实现找矿突破,通过1∶1万土壤地球化学测量,对元素地球化学特征做了分析研究,在该区圈定了7处综合异常。研究发现,矿区内Pb、Zn、Sb元素丰度较高、离散性大,成矿的潜力较大,是矿区的主要成矿元素;7处综合异常中,Ap2主要异常元素规模大、含量强度高,重叠性好,Pb、Zn找矿前景较好,可作为找矿靶区。Dalubian mining Mine in Qidong,Hunan Province is located in Guandi Miao-Dayishan area of Nanling metallogenic belt,where the metallogenic conditions are superior and it is a favourable area for exploration of tungsten,tin and lead-zinc mine.In order to achieve prospecting breakthrough in the area,through 1∶10000 soil geochemical measurements,the geochemical characteristics of elements were analyzed and studied and 7 comprehensive anomalies were delineated in this area.It is found that Pb,Zn and Sb are the main metallogenic elements in the mine area due to their high abundance,great dispersion and great metallogenic potential.In the 7 comprehensive anomalies,the major abnormal elements of Ap2 are large in scale,high in content intensity and good in overlap.The prospecting prospects of Pb and Zn are good,and they can be used as the prospecting target area.
