摘　　要：本文通过在安徽凤阳浅覆盖地区应用浅钻取样方法技术,较好地解决了土壤光谱样品的取样介质、取样深度等样品采集方面的问题;根据浅钻土壤样品分析结果,编制浅覆盖区元素地球化学图。浅钻取样的同时,又完成了对浅覆盖区下伏地质情况的揭露,辅助编制浅覆盖区基岩地质图。为浅覆盖区下一步工作提供了丰富的信息及找矿线索,特别是在凤阳江山多金属矿外围找矿的应用效果显著,表明浅钻方法技术是解决覆盖区地质调查难题的有效手段。In this paper, shallow drilling sampling technique was applied in the shallow covering area of Fengyang, Anhui Province, and the problems of sampling medium and depth of soil spectral samples were solved. In this study, the shallow drilling sampling technique was used for the first time in this area, and the problems of sampling medium and sampling depth were solved well. Based on the analysis results of shallow drilling soil samples, the elemental geochemical map of shallow overburden area is worked out. Sampling while drilling, we have completed the undercover geological exposure of the shallow overburden area, and compiled the geological map of bedrock in shallow overburden area. The formation of these basic maps provides abundant information and prospecting clues for the next work in shallow overburden areas. Especially, the application of shallow drilling technique in the exploration of Jiangshan polymetallic ore deposit in Fengyang has been proved to be an effective method to solve the geological survey problems in the overlying area.
