Abstract: The exposure structures are found at the top of the Tongzi Formation and in the Carboniferous strata in Qingchang, Bijie, Guizhou. There exist two 10-50 km-wide "black zones" directed to NNE in the Maokouan (Middle Permian) strata in Bijie. The fossils include abundant ivories, teeth and skeletons in the Quaternary strata in Weixin, and Silurian plant fossils in Yachuan of Fenggang, Maopo of Zunyi and Yujing of Weixin. The formation and evolution of central Guizhou uplift is examined as well.
