准噶尔北缘卡拉先格尔断裂带深部结构的MT探测
|
摘要
卡拉先格尔断裂是1931年8月富蕴8级大地震的发震断裂,也是阿尔泰造山带重要的多期活动断裂和阿尔泰地区晚古生代火山盆地向东延伸的限制性断裂。通过在卡拉先格尔地区5条大地电磁测深剖面测量与资料分析,获得了关于沿剖面的地壳二维电性结构。结果显示卡拉先格尔断裂在深部表现为向南西陡倾的低阻异常带。卡拉先格尔断裂地表走向与磁异常梯度带走向一致,呈北北西向展布。新的结果还发现在卡拉先格尔断裂西南侧存在一条北西走向北东倾向的次级断裂。结合卡拉先格尔断裂地表变形特征,指出该断裂不仅是走滑断裂、还是斜滑断裂,其正断活动可能造成卡拉先格尔断裂带东侧地质体的隆升与剥蚀,从而造成断裂带两侧地质体剥蚀程度与成矿特征的差异。
Kalaxianger fault was the seismogenic fault of the Fuyun 8.0 level earthquake occurred on August,1931,as well as a limited boundary fault for the Late Paleozoic volcanic basin in Altay Mountain. Magnetotelluric data along five profiles south to the Kalaxianger area were collected,the corresponding two-dimensional electrical structures of crust were obtained. New data show that the Kalaxianger fault was presented by a low resistance anomaly zone dipping SW with big angles. It stroke along the magnetic anomaly zone on the ground. Moreover,a new secondary fault striking NW with a big dip angel was discovered in the west of the Kalaxianger fault. Based on the deformation features and the attitude of the Kalaxianger fault,we suggest that the Kalaxianger fault was not only a strike-slip fault but also an oblique slip fault. Its normal sliding movement caused the east terrace to be uplifted and eroded,resulted in variety of erosion and metallogenic feature at two sides of the Kalaxianger fault.
