1.Due to overpumping groundwater, hazard of mantled karst collapse may often take place there.
因过量抽取下水，造成覆盖型塌陷灾害。
2.The later period of karst corrosion deposit experienced lateritization, had accomplished the red clay basic characteristic.
残余堆积物后期又经历红土作用，造就了红粘土的基本特征。
3.Moreover, two types of cements of limnic calcite and limnic dolomite and hydrothermal dolomite of reburial period are included in the karst rocks.
中发育有淡水方解石和淡水白云石2种胶结物类型，以及再埋藏期沉淀的热液异形白云石。
4.The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.
斜坡和表水汇集区及下水排泄区，作用相对较弱，储层不发育。
5.It's a residual mountain(unaka) which were a set of thrust blocks under the erosion unconformity.It's reservoir pore space is a fracture-vug-pore system of Ordovician carbonate karst.
