zone boundary
4.It can be concluded that: presently the eastern segment of Qilianshan fault zone and its boundary region with Zhuanglanghe fault and Haiyuan fault is in an obvious background of strain accumulation; Lanzhou and Linxia area near the southern segment of Zhuanglanghe fault display a feature of strain accumulation in certain degree.
5.Abstract: Based on 1∶1,000,000 generalized aeromagnetic survey in centraland 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.
