摘要
东天山阿其克库都克断裂为板块汇聚边界断裂,断裂分为近东西段和北东东段,两段活动特征不同.采用遥感解译、野外调查,结合分形几何学,对断裂活动特征进行研究.近东西段断裂表现为走滑性质,垂向差异运动较弱;北东东段上新世以来曾有活动,活动性不强.整个大断裂分维值低,说明断裂结构简单,活动性弱,最后一次活动具走滑性质.对断裂活动特征的研究可为研究区区域地壳稳定性评价和工程选址提供证据.
Aqikekuduk fault,which is a convergent plate margin fault,has been active since it formed.The fault can be divided into near EW part and NEE part with different characteristics.The activate characteristics were studied by remote sensing,field survey and fractal methods.The near EW part is with strike-slip feature and with weak differential vertical activity.The NEE part moved since Pliocene but the activity is weak.Fractal dimension of the whole fault is low,which expressed that the structure of the fault is simple and with weak activity and the last activity is with strike-slip characteristic.The study can provide evidence for the estimation of regional crustal stability and site selection.
