摘要:
利用区域地质、地貌遥感和地球物理等多方面的证据,标定出准南冲断带横断层。在分析米泉-乌鲁木齐-永丰和红车-巴音沟东等横断层特征及分布基础上,探讨了横断层的形成机制及地质意义。研究认为:准南冲断带横断层有先存区域性断裂和主断裂逆冲差异调节断层两种成因类型,在调节冲断带各段构造的活动性、构造变形的强度等方面具有重要的作用,并且在与主逆冲断裂联合发震、主震发生后控制余震分布等方面也扮演重要的角色。
Abstract:
Combining with the overall evidence of regional geology,geomorphic remote sensing and geophysical data, etc.,we identified the transverse faults in thrust belt of southern Junggar Basin. Based on the analyses of the distribution and characteristics of transverse fault,such as the Miquan-Urumqi-Yongfeng Fault and Hongche-Bayingou Fault etc., we discussed the formation mechanism and geological significances of transverse faults. The research results show that the transverse faults mainly have two genetic types,which played an important role in adjusting the structural activity of each section and the strength of structural deformation,and triggering earthquakes joining with the main thrust faults and controlling the spread of aftershock after the main earthquake etc.
