摘要
The eastern South China continental block can be subdivided into the Yangtze block and the Cathaycian block. The Xuefengshan intracontinental tectonic system is one important part of the Yangtze block. The authors proposed that the longitudinal arcuate and northeastward structures in the Xuefengshan intracontiental tectonic system result from a control of different block borders under the same stress field as the previous one. The first-generation NEE-striking folds are rotated from the earlier NNE-striking folds due to late block rotating. The second-generation NNE-striking folds superimpose the NEE-striking folds. The intracontinental shortening between the Yangtze and Cathaysian blocks was earlier than the collision of the South China block with the Qinling-Dabie micro-continent. The Yangtze block and the Qinling-Dabie micro-continent had rotated in Early Indosinian orogeny.
