This paper presents geochemical and zircon U-Pb and Lu-Hf isotopic data for Neoproterozoic meta-sedimentary rocks in the Xiangxiang-Liling area, eastern Hunan Province and Guiyang area, southeastern Hunan Province. Geochemical data show that the sedimentary rocks from these two areas have similar and moderate composition maturity. Consequently, the sediments in the eastern Hunan Province change significantly from Late Neoproterozoic(Sinian) to Early Paleozoic time(Middle Cambrian), suggesting a tectonic event occurring between them. It is this event that probably bright about the uplift of Cathaysia Block or subside of the Yangtze Block, leading to that the Xiangxiang-Liling area, eastern Hunan Province receive the clastic materials from the Cathaysia Block in Early Paleozoic time. This event is probably related to the Pan-African Movement in East Gondwanaland.
