活断层是新构造运动和现代构造运动重要的地质表现之一。新构造运动活跃地区的活断层,其地貌显示十分清楚,它们常常组成断块山和断块盆地的边界,控制着河流和湖泊的发育。由于活断层的类型、活动程度以及它们所在地理位置气候条件的不同,它们在地貌上的表现也各不相同。一般说来,新构造运动强烈的地区,活断层的地貌形态容易保留下来,因为这类地区的构造活动速度大于或远远大于侵蚀速度。如果其一地区沿活断层的构造运动速度等于或小于侵蚀速度,那么活断层在地貌上的反映就不明显,或者完全没有反映。在干旱
The active fault is one of the important geological manifestations of neotectonic movement and modern tectonic movement. The active faults in the newly developed active areas are well-defined, and often form the boundaries of fault blocks and fault blocks, controlling the development of rivers and lakes. Due to the types of the active faults, the degree of activity, and the climatic conditions of their geographical location, they also perform differently on the landscape. In general, in the newly tectonically strong regions, the morphology of the active faults can easily be preserved because the tectonic activity in these regions is faster or greater than the erosion rate. If the rate of tectonic movement along an active fault in one area is equal to or less than the erosion rate, then the active fault will not be apparent in the landscape or completely reflected.
