| 摘 要： | 秦、祁、昆三大造山带结合地区的物质组成及结构特征显示,其间存在不同时期发育起来的陆缘、陆内转换断层,受其制约,造山带内曾发生大规模侧向运动和由此引起的岩心活动及复杂的构造变形。据此,结合演化可分三阶段,并且秦、祁、昆三大造山带间并不存在东西向贯通的单一结合带,而是在转换断层作用下,分阶段逐步完成了转换结合的结合方式。

| Abstract: | The composition and structure of the junction part of three great orogenicbelts (Qinling, Qilian and Kunlun) show that several epicontinental and intercontinentaltransform faults developed in different epoch. Controlling by these faults, a large-scalelateral movement,which led to magmatism and complex tectonic deformation, were tokenplace. According to the view of authors. the junction and evolution of these three greatorogenic belts have been gradually completed in three stages. The east-west trending singlejunction zone that linked up these three great orogenic belts is not existed. |
