| 摘 要： | 东昆仑和西秦岭两造山带间的关系历来存有争议。笔者认为在全面分析两造山带间由平行造山带走向的侧向运动所造成的基本地质构造现象的基础上,两造山带间是以侧向运动形式为主,这种侧向运动于古生代早期就已发生,至三叠纪末期因发生侧向碰撞造山而结束,鄂拉山次级造山带并由此而产生,同时也完成了秦昆两造山带结合,并进一步指出:西秦岭和东昆仑两造山带并非是在统一造山机制下所形成的同一造山带。

| Abstract: | There are always arguments on the relationship between East Kunlun andWest Qinling orogenic belts. Through an analysis on the basic geological and tectonicphenomena caused by lateral movement, as a main form of movements, according to theauthor's opinion, the lateral movement began at the earlier stage of Late Palaeozoic Era andfinished at the end of Triassic Period with a lateral collision and orogeny, in a result of theformation of Ngolashan sub-orogenic belt and the connection of Qinling and Kunlun.TheWest Qinling and East Kunlun are not a same orogenic belt formed in an unite orogenicmechanism. |
