渭河盆地北缘口镇断裂上盘黄土磁组构特征及其意义
|
摘要
对渭河盆地北缘口镇断裂上盘黄土进行系统的磁组构特征分析。发现磁化率各向异性(AMS)具有典型压扁型弱变形,磁面理为主导因素,并控制磁线理。磁化率椭圆K_(max)方向等面积赤平投影与玫瑰花图解存在近正北向、北西西和南西三个优选方向。表明口镇断裂带上盘黄土磁组构特征指示断裂构造应力在130~55.9 ka至少出现三次方向变化。
Magnetic fabric of aeolian fine-grained sediments on hanging wall of Kouzhen faults in the northern margin of the Weihe basin systematically analyzed. The results showed that the anisotropy of magnetic susceptibility( AMS) deformed weakly with a typical flattening type,and magnetic foliation is the dominant factor with controlling the magnetic lineation. The preferred orientation of Kmaxis nearly N,NWW and SW. It shows that the tectonic stress direction of Kouzhen faults existed three changes from 130 ka to 55. 9 ka.
