    Abstract:

    The boundary between the Mesoproterozoic and Neoproterozoic in the Yangtze Block in southern China is correlated with a series of orogenies. The stratigraphic correspondence between the Jinning Orogeny, the Wuling Orogeny and the Xuefeng Orogeny is controversialdue to the defitient age data in high resolution that causes the chaotic stratigraphic deivisions. We combined previous studies of the Mesoproterozoic—Neoproterozoic boundary and discussed the petrography,geochemistry and isotopic chronology. With new evidence of the plate tectonics and characteristics of lithology, we discussed the stratigraphy of the Jinning, Wuling and Xuefeng Orogenies. We found evidence that the Jinning,Wuling and Xuefeng Orogenies are overlapped in some areas of Yangtze Block. The end of Jinning Orogeny is around 1000 Ma correlated to strong metamorphism of the strata in Kunyang Group and create the igneous basement of the Yangtze Block. The specified boundaries of the orogenic events are critical to further stratigraphy divisions and correlations of the Yangtze Block for the Mesoproterozoic and Neoproterozoic.
