| Abstract: | In this paper the geometrical pattern of the thrust and nappe in Xiaolongmen area is studiedin details for the first time. A new S-mode of the thrust is preliminarily built up. The nappes are divid-ed into two structural belts on the basis of distribution of moderate-minor structure and characteristicsof rock deformation. The analysis of folding pattern and section combination of underlying rock systemare also carried out. The determination of geometrical style and formation mechanism of the thrusts andnappes in Xiaolongmen area provide reliable basis for scientific researches on the gigantic nappe struc-ture in Xuefeng mountain area, Hunan province. |
