%X 贵安直管区内岩溶发育，但对岩溶的发育过程认识尚不清楚。本文通过区域地层分布及特征对比，结合构造演化史综合分析，重塑了贵安直管区的沉积–构造动态演化过程，并以此限定了岩溶发育的主要时段。提出区内岩溶的形成过程主要分为3个期次：第一期形成于晚三叠世–早侏罗世(~230~200 Ma)，第二期形成于早白垩世(~145~100 Ma)，第三期为新生代以来(~66 Ma)，其中第三期是区内岩溶管道发育的高峰时期，特别是2.58 Ma以来的多期构造升降形成不同海拔标高内典型岩溶管道分布。该研究对直管区岩溶的形成与演化进行了精细刻画和时间标定，一定程度上提升了岩溶研究的程度，为后续开展城市地下空间利用提供了详细的地质依据。<br />
Karst is widely developed in Gui’an direct territory, but the process is not well understood. Based on the correlation of regional stratigraphic distribution and characteristics, combined with the comprehensive analysis of structural evolution history, this paper reshaped the sedimentation-tectonic dynamic evolution process in Gui’an direct territory, and thus defined the main period of karst development. It is suggested that the karst formation process in this area can be divided into three stages: the first stage was formed in the Late Triassic to Early Jurassic (~230~200 Ma), the second stage was formed in the Early Cretaceous (~145~100 Ma), and the third stage was formed since the Cenozoic (~66 Ma). The third stage, especially since 2.58 Ma, was the peak period of karst pipeline development in the area, and the distribution of typical karst pipeline in different elevations was formed by multiple tectonic elevations. This study has carried out a fine characterization and time calibration of the formation and evolution of karst in the direct territory, which has improved the degree of karst research to a certain extent, and provided a detailed geological basis for the future utilization of urban underground space.
