The Yangtze Block in s.uth China is.one of the important regions.where Neoproterozoic glacial rocks.are well developed and s.udied. However, the clas.ification and correlation of the Neoproterozoic glacial s.quences.in the central Yangtze Block s.ill remain controvers.al among Chines. geologis.s. The original s.nian s.ctions.around the Yangtze Gorges.Region became an official s.andard for clas.ification and correlation s.nce the 1950s. s.bs.quent regional geologic s.udies. however, res.lted in different clas.ification and correlation, becaus. of its.incompletenes.. We s.lect one of the complete s.ctions.in the bordering areas.of Xiang (Hunan), Qian (Guizhou) and Gui (Guangxi), as.a s.andard of clas.ification and correlation. The temporal and s.atial dis.ribution, i.e. the s.ratigraphic architecture, of the glacial rocks.in the central Yangtze Block is.s.gges.ed. Our res.lts.indicate that the glacial s.quence on the Yangtze Block was.depos.ted during the Nantuo Ice age, the Datangpo Interglacial age and Jiangkou Ice age, in des.ending order.
