摘　　要：皖东南地区膨润土矿资源相对丰富,通过对区内膨润土矿床(点)调查、采样测试,分析总结了膨润土矿地质特征、矿石类型和性能等,认为膨润土中蒙脱石含量较高,物理化学性能满足冶金球团土、活性白土、无机凝胶等工业需求;结合成因类型、成矿规律分析,指出了找矿方向,圈定了3个成矿远景区,对该区膨润土找矿工作具有一定借鉴意义。The mineral resources of bentonite in southeast Anhui are relatively rich.Through the investigation,sampling and testing of bentonite deposits,the geological characteristics,ore types and properties of bentonite are analyzed and summarized.The content of montmorillonite in bentonite is high,and its physical and chemical properties meet the industrial needs of metallurgical pellets,active clay,inorganic gel,etc;By analyzing the genetic types and ore-forming laws,the prospecting direction has been pointed out,and three ore-forming prospects have been delineated,which has certain reference significance for the exploration of bentonite in this area.
