| 摘 要： | 骊山山前断裂是发育于骊山凸起北侧的一条近东西走向并向北倾斜的正断层。断裂形变遗迹,地貌标志、新生代沉积物的厚度变化特征表明,该断裂第四纪晚期以来,在区域构造引张应力场的控制下,一直作掀斜式的倾向拉张运动。在长期的形变过程中表现了蠕滑和粘滑两种活动方式。现在仍在以蠕动的方式运动着。

| Abstract: | Lishan piedmont fracture is a nearly westeast strike and northward dip normal fault developed on the north side of raised Lishan. The characteristics of the fracture deformation traces, the geomorphic marks, and the thickness of the Cenozoic Era sediment indicated that this fracture has got continuous tilted dip tensile movement under the control of regional tectonic gravitational tensor stress field since the later period of Quaternary. In the long-term of deformations it showed two kinds of motion, that is, creep slipping and stick slipping. Now, it is still following the first slipping. |
