摘要
本文根据野外调查资料及重力、航磁等资料,对柴达木盆地及其邻区的主要活动断裂的大地构造位置、产状、深度和第四纪活动特点等进行了分析研究,並讨论了这些断裂与地震活动的关系。这一地区的地震活动强度与断裂深度有关,具左旋运动特征的全新世近东西向活断层与强地震活动的关系最为密切。
This paper studies tectonic position, occurrence, depth and active characteristics in Quaternary Period of main active faults in Chaidamu Basin and its vicinity, based on field investigation data, gravity and aeromagnetic data, discusses relationship between the faults and earthquakes. In this area, earthquake activity intensity relates to fault depth; active faults of EW with left lateral movement characteristic of Holocene is closely relative to strong earthquake activity.
