| 摘 要： | 根据青藏高原中西部1:100万航磁概查结果,对雅鲁藏布江缝合带、塔里木盆地南部边界、高原内部几条规模较大断裂和区域性负磁异常带等高原地区几个有关的地质和地球物理问题进行了解释和探讨,获得了与以往不同的认识,这对青藏高原的深入研究具有重要意义。同时,也表明了通过航磁概查所获得的青藏高原中西部最新航磁图用于地质问题的研究具有很好的效果。

| Abstract: | Based on 1:1,000,000 generalized aeromagnetic survey in central and western Qinghai-Tibet plateau, this paper has made interpretation and investigation on such geological and geophysical problems related to the plateau area as the Yarlung Zangbo River suture zone, the southern boundary of Tarim basin, several large-scale faults within the plateau and regional negative magnetic anomaly zones and, as a result, obtained some new understanding different from previous opinions, which is of great importance in the further deepgoing study of Qinghai-Tibet plateau. It is also demonstrated that the application of the newest aeromagnetic map of central and western Qinghai-Tibet plateau based on generalized aeromagnetic survey to the study of geological problems is very effective. |
