摘要
Combined with geological data,using deep structure informations, this paper reinterprets 3D lithospheric structure of Hunan and South China, and brings new knowledge of the tectonic characteristics and the location of the Yangtze-Cathaysia plate convergence zone in Hunan Province, and about the tectonic characteristics of Jiangnan ancient land. The study consider that the YuanMa-Dongting-Hengyang arc gravitational high is caused by crystalline basemental uplift with paleo-volcanic cone, and infer that there exist paleo-volcanic island-chain along Mayang-Taoyuan-Yiyang-Nanqiao, and hidden residue paleo-volcanic islands along Liuyang-Hengyang, east Hunan Province. The authors drew the shape of the rigid upper mantle block of Yangtze and Cathaysia paleo-plate. It conferred that the Yangtze-Cathaysia intermediate zone were paleo-Jiangxi-Hunan-Guangxi South China ocean.
