The study of karst development in Puding region, Guizhou Province reveals that karst is more intensively developed in bioclastic sparitic limestone and biomicrite, and underground rivers are also well developed.There is an uplifted Karst peneplain that was formed from Early Tertiary or Late Cretaceous age, in Puding region.The mogotes may be formed in Neogene when it was tropical climate.But it is distinctly subtropical climate now.The mogotes are subdued usually less than 200M high.They are known as relict mogotes.Owing to the recent strong uplift of the Plateau, the rivers have incised depply into the Plateau and thus formed steep gorges.The development of Karstification is not abated but enhanced in puding region from river-valleys to waterdivides.The distribution of the Karst topography reveals that it is in zontion horizontally and in Layer verlically.There develop caves.They may be grouped into three categories.(1) caves formed by a belt of downward filtration, (2) caves fit in with the baseleve] of the Karst erosion, and (3) caves of the inactive deep Karst.
