摘要
本文从现代、地史时期岩溶剥蚀速度及岩溶铝土矿的形成等方面探讨岩溶在古地理研究中的重大作用,从而提出稳定地区“缺失”某一时期地层,并非该时期为陆;而是前期仍有沉积,后期才真正上升为陆,遭受剥蚀。
Based on the speed of karstification and the formation, etc.of Karst bauxite both in the present and in the past, this article deals with the important effect of karstification in the palaeogeographic study; pointing out that stable areas were not land at first but short of the strata of certain period, and that there were still sediments at the beginning of the geologic time and it was at the end of the geologic time that the areas rose to really form land and suffered erosion.
