摘　　要：通过对黄龙山—双港口地区1:1万土壤地球化学测量结果分析,探讨黄龙山—双港口地区元素含量、分布及组合,将区内元素分为Cu-Pb-Zn-Au-Ag-As-Sb中低温组合和W-Sr-Co-Mo高温组合,发现石英闪长岩、栖霞组中Cu、Au、Ag、Pb成矿可能性最大。通过计算各元素异常下限,圈定3处地球化学综合异常,结合地质物探综合分析圈定王家洞和刘家垄2处重点找矿靶区,其中刘家垄找矿靶区钻探工程验证发现铜矿体。Based on the analysis result of soil geochemical survey of 110000 scale in Huanglongshan-Shuanggangkou mining area,the element content,distribution and combination features are discussed.The elements in Huanglongshan-Shuanggang area are divided into Cu-Pb-Zn-Au-Ag-As-Sb medium-low temperature combination and W-Sr-Co-Mo high-temperature combination.It is found that Cu,Au,Ag and Pb mineralization are the most likely in quartz diorite and Qixia Formation.Three comprehensive anomalies are delineated by calculating the anomaly lower limit of each element.According to the distribution characteristics of comprehensive anomaly and combined with geological and geophysical data,two key prospecting target areas are circled out.Among them,copper ore body is found in Liujiarang prospecting target area after drilling verification.
