| Abstract: | The Zhangbaling nappe lies in the northern margin of the South China block, east of the Tanlu fault zone. It belongs to the western part of fold and thrust tectonics of the Lower Yangzi area with a trend of NNE. The Dabie belt is to its northwest and Chuxian-Susong tight fold and thrust belt is to its southeast. It covers an area of about 1100 km2. According to the 1evels of thrusts and types of folds, the Zhangbaling nappe can be divided into the Feidong rappe and the Shiji rappe. Based on data of field observation, drills and geophysics, the authors demonstrated that the Zhangbaling thrust rappe is a complex thrust structure with a movement more than 16km southeastward. The isotope age of its granites and metamorphic belts is commonly 165～240Ma. This suggests that it was shaped during the early Mesozoic time when the North and South China blocks co11ided. After it was fomred, the Tanlu fault, which is 1eft-lateral slip, destroyed its integrity. Therefore, the Tanlu fault zone is not its northwest boundary It is suggested that the western houndary of the Zhengbaling rappe is located in the south of Dabie block. |
