| Abstract: | Comprehensive analysis of the geological composition and structural features in the southern Qinling indicates that this region passed through four evolution phases, i. e. basement formed at the time from Archaen to early and middle Proterozoic era, marginal evolu tion of the Yangtze continent from the late Proterozoic to early Paleozoic periods, formation of sea trough between Mianxian and Shiquan in Paleozoic time and closed orogeny and intracontinental orogeny in the Yanshanian time, forming a corresponding composition between lithological formation and structural deformation. |
