| 摘 要： | 通过地层关系、构造变形分析及有限应变测量等方面的研究表明,位于龙门山北段推覆构造前缘的唐王寨向斜主体,为大型外来岩块。它与龙门山中段彭灌飞来峰群一样,是随龙门山推覆隆起而在重力作用下形成的滑覆体。

| Abstract: | The Tangwangzhai syncline of Longmenshan is believed to be a big gravity gliding nappeby the following facts: 1).Anomalous strata relationship; 2).Disharmonic structures; 3).Special spoon-shaped faults associated with listric normal faults and thrusts; 4).Movement directions of gliding sheets; 5).Deformation and strain distribution of gliding sheets. The formation of the gliding nappe of Longmenshan is based on upwarping caused by thrust andnappe tectonics. |
