| 摘 要： | 湖北谷城县观音坪地区推覆构造为武当山巨型推覆构造的一部分。该区推覆构造结构复杂,顺层滑脱及韧性逆掩有机地组合在一起构成了多重滑脱-推覆构造。该区地壳经历了多期次、多体制、多层次的复杂变形,但无认是外来岩块还是原地岩系,其构造格局和样式均以同推覆期构造为主导。

| Abstract: | Decollement-nappe structure of the Guanyinping region is a part of nappe structure of Wudang Mountain. The author discovered triple decollement-nappe structure in the Guanyinping region. The master fault surface is the Qingfong fault belt. Structural deformation is strong in the area. There are klippes , fensters, many A-type folds, sheath folds, mylonite belts and ductile shear zones. There are superimposed folds in autochthon and allochthon. Great majority of them are push folds. Structural pattern of subduction rocks is imbricative fan. During the indosinian orogeny, part of the Qingling regenerated geosyncline folded system was overthrusted from north to south upon the Yangzi Platform. The nappe displacement is about 140 km in distance. |
