摘要
雷波地区的古岩溶主要指下二叠统灰岩顶部在其形成后并在其上覆玄武岩沉积前，由于环境影响而发育的古岩溶现象。因其分布广泛，对水利枢纽工程岩溶水渗漏评价有重要意义。通过典型剖面沉积特征的综合对比，总结了本区古岩溶发育的一般特征，并在分析、恢复古地理、古气候环境的基础上。
The paleokarst of Leibo area is pointed to paleokarst phenomenon which had developed on the top of Lower Permian limestone before the basalt formed on it. It is of great significance for predicting the karst percolation of hydraulic engineering scheme for its wide distribution.By comprehensive correlation of typical profiles,this paper presents the common developmental characteristics of paleokarst,discusses the reason of weak paleokarst development in this region on the basis of analysis and recovery of paleogeography and paleoclimate.
