| 斜向碰撞引起的走滑转换现象,是大陆造山带一种常见的构造样式。金沙江结合带中的斜向走滑构造是最夺目的定型构造。它的形成演化,成为大陆造山带陆内汇聚阶段的主要地质事件。笔者以区域地质调查资料为根基,利用斜向走滑构造的理论,对金沙江结合带拖顶地区的一些地质问题进行讨论。 |

| Abstract: |
| The strike-slip transform structures originated from oblique collision are believed to be the principal structural patterns commonly observed in continental orogenic zones. The occurrence of oblique strike-slip structures along the Jinshajiang suture zone in northwestern Yunnan resulted in the closure of the renewed Jinshajiang oceanic basin, and continent-continent collision at the end of Indosinian. The present paper deals, in detail, with the oblique strike-slip structures and other geological phenomena in the Tuoding region, Yunnan based on the data on the geological survey of the Ludian and Xiaruo sheets, The oblique escape is interpreted to be the cause of thinning of the crust and uplift of the Qinghai-Xizang Plateau and thus to be the important patterns of the interplay of the continental masses along the Jinshajiang suture during intracontinental convergence. |
