摘　　要：红运水源地地处嘉祥断块北部,主要含水层为奥陶纪三山子组中细晶白云岩,且岩溶发育,在岩性上中细晶白云岩>细晶白云岩>泥灰岩>灰岩和豹皮灰岩>微晶白云岩。区域断裂构造发育,多以张性断裂为主,一般为带状岩溶发育,深度143~330 m,与断裂构造的走向基本一致,为地下水的富存和运移提供了良好的场所和通道。奥陶系顶板不同埋藏深度形成的高差,为岩溶地下水径流提供了强烈的地下水动力条件。通过研究岩溶发育特征,对比区域地质、水文地质条件,证实岩溶发育与地层岩性、地质构造、地下水动力条件、埋藏深度等关系密切。通过对比钻孔地层资料,分析了红运水源地富水性条件,地层岩性是岩溶发育的物质基础,地质构造是岩溶发育的控制因素,水动力条件是岩溶发育的外在因素,对指导北方覆盖型岩溶地下水勘查及寻找覆盖型岩溶水富集区具有借鉴意义。Hongyun water source is located in the north of Jiaxiang fault block.Its main aquifer is middle fine grained dolomite of lower Ordovician Sanshanzi formation.The basic law of karst development in lithology is medium fine grained dolomite>fine grained dolomite>marlite>limestone and leopard skin limestone>microcrystalline dolomite.The regional fault structures are developed,and most of them are extensional faults.The karst development is generally zonal,and the development depth is generally between 143~330m,which is basically consistent with the strike of fault structures,and provide a good place and channel for the accumulation and migration of groundwater.The fluctuation of Ordovician roof provides strong groundwater dynamic conditions for karst groundwater runoff.By studying the characteristics of karst development and comparing with regional geological and hydrogeological conditions,it is confirmed that karst development is related to stratum lithology,geological structures,groundwater dynamic conditions and burial depth.By comparing with the strata data of exploration holes,water rich conditions of Hongyun water source area have been analyzed.The suitable lithology is the material basis of karst development,geological structures are controlling factor of karst development,and the strong circulation of hydrodynamic conditions is the external factor of karst development,which is the basic law of the special enrichment of karst water in Hongyun water source area.It can be used to guide the investigation of buried karst groundwater in Northern China and to find the area of karst water enrichment.
