Abstract: The gliding plane within the nappe structures of the Jinpingshan area, Sichuan is interpreted as a (ductile) shear zone. The nappe structures in this area are generally overthrusted and stacked by a number of slices and sheets, with thrust outliers in the front of the nappe structures. It is inferred that the shortening distance is estimated to be about 30 km in terms of detailed study of the ductile shear zones and thrust outlies in the study area. The boundary fault zone on the western Yangtze has been redelineated as the Chapuzi-Bazhe(("geosyncline)-platform") regional renewed fault zone (ductile shear zone) rather than the Jinpingshan fault (defined) before.
