摘　　要：为了探讨北淮阳构造带东段(安徽境内)铅锌钼等多金属矿的找矿潜力,选取了舒城县畈胡家地区作为重点研究区域。本次研究工作基于以往勘查成果,重点结合已发现的多条钼、铅锌多金属矿体的地质特征,进一步对研究区成矿地质背景、地球化学特征、地球物理特征等开展综合研究。经研究发现,区内大地构造位置、辉钼矿铅锌矿矿化分带、燕山期正长岩体发育、磁异常与岩体叠加、钼铅锌异常发育等,均与沙坪沟钼矿床具有相似性。认为研究区具备寻找沙坪沟斑岩型钼矿的潜力,为区内实现找矿突破提供了有益参考。In order to explore the prospecting potential of lead-zinc-molybdenum and other polymetal-lic deposits in the eastern section of the North Huaiyang tectonic belt(Anhui Province),the Fanhujia area of Shucheng County was selected as the key research area.Based on the previous exploration results,this re-search work focuses on the geological characteristics of several discovered molybdenum,lead and zinc polymetallic ore bodies,and further conducts a comprehensive study on the metallogenic geological back-ground,geochemical characteristics and geophysical characteristics of the study area.Through research,it is found that the geotectonic location,molybdenite lead-zinc mineralization zoning,Yanshanian syenite body development,magnetic anomaly and rock mass superposition,molybdenum,lead and zinc anomaly development in the area are similar to those of Shapinggou molybdenum deposit.It is believed that the study area has the potential to find Shapinggou porphyry molybdenum deposit,which provides a useful reference for the realization of prospecting breakthrough in the area.
