| 摘 要： | 龙门山断裂带位于四川盆地西缘；青藏高原东部；为四川盆地与松潘-甘孜地块的接触构造边界。龙门山地区海拔从东侧100 km外四川盆地的500 m突升至3 000 m高度；明显地标注了青藏高原的东部边界；其隆升机制也引起了国内外地质工作者的广泛兴趣；并且提出了多种隆升机制模型。在本次研究中；我们利用SinoProbe-02深反射地震剖面数据对龙门山地区的隆升机制进行研究；从而进一步探讨龙门山地区隆起造山的独特性；并讨论其与传统意义中的造山带的区别；认为龙门山断裂造山带为板块内部构造活动引起岩石圈隆起所形成的。本文的研究结果将使我们更深刻地了解龙门山地区的构造活动特点；并且有助于了解青藏高原东缘对印度-欧亚板块碰撞的构造响应。

| Abstract: | The Longmen Shan range is located between the Sichuan Basin and the eastern Tibetan Plateau. It acts as a tectonic boundary between the Sichuan Basin and the Songpan-Ganzi terrane. The Longmen Shan range rises above the sea level to about 3 000 m from 500 m of the Sichuan Basin to the east within a scope of 100 km,which has obviously marked the eastern boundary of the Tibetan Plateau. Its rising mechanism has attracted great interests among geologists and numerous models were proposed accordingly. In this paper,based on the SinoProbe-02 310 km-long deep seismic reflection profile,we carry out a study on the mountain building process of the Longmen Shan Range. A further discussion will be given to study the uplifting mechanism of the Longmen Shan range. The results will be used to compare with the conventional orogenic process. In addition,the results of this paper will help us further understand the tectonic features of the Longmen Shan range and will contribute to greatly understanding the tectonic response of eastern Tibet to the ongoing India-Eurasia collision. |
