摘要
依据推覆构造形成的力学机制，将推覆构造分为边冲推覆构造、滑覆构造和韧性推覆构造三大类型。通过对武当山地区的综合研究，提出武当山地区为一韧性推覆构造，其几何样式为一个巨型的“ＡＢ”型褶皱。并证实武当山地区为剪切变形区，其变形机制为简单剪切机制。文章还提出整个东秦岭造山带为剪切型造山带。
Nappe tectonics was classified into three types thrust nappe tectonics, slipping tectonics (stretch nappe tectonics) and tenacity nappe tectonics. By comprehensive study, Wudang Mountain tenacity nappe tectonics has been pointed out at the first time. Its geometrical pattern is a giant 'AB'type of fold. It was proved by many means,that mechanism of deformation in Wudang Mountains area is simple shear. The whole Eastern Qinling orogenic belt is a shear orogenic belt. The concept,characteristics and important significance of shear orogenic belt have been discussed in the article.
