利用跨断层形变资料研究天山中段断层现今活动特征
|
摘要
利用2001年以来天山中段多个跨断层形变场地的测量资料,从断层运动方向和断层平均速率2个方面分析天山中段3条断层现今活动特征。结果表明,霍玛吐断裂呼图壁段断层的活动性质为正、逆断和左、右旋交替活动;北轮台-辛格尔断裂库尔勒段断层表现为右旋运动特征,活动性质为逆断性;妖魔山F2断裂乌鲁木齐段的断层活动性质以逆断为主。妖魔山F2断裂乌鲁木齐段断层的活动程度最高,霍玛吐断裂呼图壁段最低。霍玛吐断裂、北轮台-辛格尔断裂、妖魔山F2断裂垂直方向上基本均处于张性变化,前两者水平向处于挤压状态;断层活动速率的时间进程具有阶段性特征,各个时间段转折点有较好的匹配性。
Based on measurement data of multiple faults in the middle Tianshan region since 2001,the current fault characteristics are analyzed from fault movement direction and fault average velocity.The results show that the activity of the fault alternates from positive to inverse,from left to right.Movement characteristics of the north Bugur-Qinggir fault is right,the activity is inverse.The activity of the F2 fault of Yamarik hill is inverse.The activity is highest in the F2 fault of Yamarik hill,and the Khorgos-Manas-Tugulu fault is the lowest in activity degree.The Khorgos-Manas-Tugulu fault,the north Bugur-Qinggir fault,and the F2 fault of the demon mountain are all in the vertical direction,and the first two horizontal directions are in the squeeze state.The time course of the fault activity rate has a stage characteristic,and the turning points of the fault have a good match in different periods.
