【摘要】 秦岭造山带是横贯我国中部著名的大陆造山带,是大陆构造中典型的陆内造山带。这种类型的造山带没有经历洋壳俯冲形成的那种主缝合带性质的造山带;也不是华北与扬子"板块"相互作用形成的对接或碰撞造山带;更不是所谓的复合型造山带。从秦岭造山带的组成、不同深度的结构特征、立交桥构造、盆-山转换中的结构样式、商丹带与勉略带的构造特征以及中央造山系(秦岭)中独特的南北向构造,深入讨论这些特征在秦岭造山带中的非板块构造属性;综合分析这些资料的基础上,建立了秦岭陆内造山带形成的抽拉-逆冲岩片构造(抽拉构造)模式。更多还原

【Abstract】 Qinling orogenic belt is a famous orogenic belt in central China,and it is also a typical intracontinental orogenic belt of continental tectonics.This type of orogenic belt did not undergo subduction of ocean crust to form such orogenic belt with main suture zone.It is not the collision orogenic belt that formed by the interaction between North China plate and Yangtz plate,and also not so-called composite orogenic belt.According to the composition,structural characteristics of different depth,cross-bridge structure,structural style in the transformation of basin and mountain,the structural characteristics of Shangxian-Danfeng tectonic zone and Mianxian-Lueyang tectonic zone as well as the distinct north-south direction structures in the central orogenic system(Qinling),the non-plate features of these characteristics are discussed.On the basis of above discussion,the thrust-Choula(or Choula)tectonic model for the formation of Qinling intra-continental orogenic belt is built.更多还原
