| 摘 要： | 塔中地区下奥陶统鹰山组见发育程度不等的多种岩溶现象,存在规模不同、形态各异的岩溶缝洞系统.一个发育完整的层间不整合岩溶通常由表层岩溶带、垂向渗滤岩溶带、径流岩溶带和潜流岩溶带构成.岩溶带发育程度与深度因受到地区、岩性、构造部位、古地貌位置、古水文条件、暴露时长等因素影响而差异较大.

| Abstract: | Various karst phenomenon developed in Lower Ordovician Yingshan Formation of Tazhong area,appears in different scale,different forms of karst fracture cave system.A completely developed the layer unconformity karst can be divided into superfacial karst zone,vertical percolation dissolvedzone,radial flow dissolved zone and groundwater flow zone.Karst development degree and depth vary with the change of region,lithology,tectonics,landform position,ancient hydrological conditions and duration of exposure and other factors. |

| Keywords: | layer unconformity Karst characteristic of Karst division karst division area Lower Ordovician Yingshan formation TaZhong area |
