| 摘 要： | 文章把龙门山推覆构造划分为4个推覆体和3个滑覆体。分别叙述了它们各自的变形特征。计算了造山带的地壳缩短率为42～63%。最后确认了龙门山推覆构造的推覆模式是推覆滑覆叠加模式,其发展方向为由北西向东南,扩展方式为背驮式(或前展式)。

| Abstract: | This paper devides the nappe structure into 4 nappes and 3 slipping blocks for this region.Their strain characters of deformations are described individully. The crustal shorttenning is calculatedas from 42% to 63% for this orogenic belt. The nappe model for this zone is a superposed pattern be-tween slipping blocks and nappes with developing direction from NW to SE, spreading type of thisnappe structure zone is "Piggyback Type". |
