Abstract:This paper firstly analyzes the lithological features,the thickness of sequence,metamorphical features and the sedi-mentary environment of seven Nanhuan-Permian combined sections from South China,then analyzes the petrological assembla-ges including ophiolites,basalts,island arc igneous and the TTG-GG suites (granites)from the area of south margin of Yan-gtze continental block and the area of Cathay accreting block and lastly analyzes the basin features based on the lithology of each unit (formation)from South China.Based on the above-mentioned analyses,four stages of tectonic evolution of South China are identified and it is concluded that the collision between the Yangtze continental block and Cathay accreting block occurred at the end of the Early Paleozoic along the northeastern part and the collision along the southwestern part occurred at the end of the Permian.
