摘要:
对骆驼山地区构造以及溶洞进行了详细的地质调查工作，在1：2000的地质调查中，重点调查了构造与溶洞的分布特征.通过综合研究溶洞的形成与构造的关系，从溶蚀及冲蚀、崩塌和堆积两方面论述了溶洞的形成条件，并根据溶洞高程对比，推测溶洞堆积物的形成时代，总结出溶洞的形成规律，为进一步研究第四纪哺乳动物演化规律提供了基础地质资料.
Abstract:A detailed investigation was carried out on the structures and karst caves in Luotuo Mountain, with the 1:2000 geological survey focusing on their distribution characteristics. Through comprehensive study on the relationship between formation of karst caves and structures, the paper discusses the forming conditions of karst caves from the aspects of corrosion and erosion, as well as collapse and accumulation, infers the formation age of karst cave accumulation according to the elevation comparison of karst caves, and summarizes the formation rule of karst caves, which provides basic geological data for further study on evolution law of the Quaternary mammals.
