| 摘 要： | 利用遥感技术，在青藏高原东北部发现了祁连山西段旋卷构造、柴北缘赛什腾山旋卷构造、柴达木西南祁漫塔格山弧形扭动构造及祁连东部大型旋卷构造等四个旋卷 (扭 )构造。分析了这些旋卷 (扭 )构造形成的地质条件与地球动力学过程，认为这一重要发现不但对青藏高原大陆动力学研究具有重要的科学意义，而且对进行资源预测还具有一定的实用价值。本文还指出 Tapponnier的“走向滑移线场和构造逃逸理论”存在两点明显不足，我们的发现及研究是对该理论的补充和完善。

| Abstract: | By remote sensing technique, we found four vortex structures,including the vortex structure of the western Qilian mountain,Saishenteng mountain vortex structure of the north margin of Qaidam,Qimantage mountain arcuate shear structure of the southwest of Qaidam and large－ scale vortex structure of the eastern Qilian mountain.We analyzed forming mechanism of these vortex structures and pointed out that these findings had scientific significance in studying the continental dynamics of Qinghai－ Xizang Plateau and practical significance in exploring mineral resources of this area from now on.
This paper also pointed out that the theories “ strike－ slip line field and structure escaping” put forward by Tapponnier had two distinct insufficiencies and at the same time,our findings and studies supplement and perfect these theories. |
