Abstract Research on using remote sensing technology to extract the ductile structure information was conducted in this paper. The tectonic deformation history in Wudang area is complex, represented by ductile shear deformations. The thrust and gliding nappe ductile shear zones in Wudang area were analyzed by using ETM remote sensing image, and the results show that, although there is no significant abnormal interface of the shear zones in the remote sensing image, the tones of the image on each side of the ductile shear zone are obviously different because of the different geological components. Thus good identification results of the image characteristics and the direction changes of the foliation lineation combination can also be obtained by the wavelet analysis and the extraction of the foliations. Using the methods mentioned above, the authors interpreted and analyzed six typical examples including the Yunxi-Yunxian gliding nappe shear zone and the Fangxian-Zhushan thrust nappe shear zone, and the result is consistent with the practical investigation, thus providing a useful reference for the remote sensing interpretation of the ductile shear zone.
