摘要
讨论了华北地区奥陶系马家沟组灰岩（Ｏ２）岩溶研究中的几个问题，包括沉积岩溶、暴露岩溶、埋藏岩溶、现代岩溶及陷落柱等。指出了沉积岩溶和暴露岩溶洞穴不能保存或保存甚少，但对后期的岩溶发育具有重要控制作用；埋藏岩溶中的构造期（燕山—喜马拉雅山期）岩溶是现今奥陶系灰岩岩溶面貌的定形期；最后。
Several problems concerning karstic study of Majiagou limestone in area of North China are discussed in this paper. It includes depositional karst, emergence karst, buried karst, modern karst and karstic collapse pole etc. It is presented that the caves of depositional karst and emergence karst can not be existed or can be less existed, but it is of important control to the development of buried karst, and tectonic period (Yanshan Ximalaya period) karst in bury period,which is determinant on the formation of Ordovician limestone karst landform at present. Finally, study thought of Ordovician limestone karst is put forward.
