| 摘 要： | 大地震产生的断错,能改变震前的地表形态,这种改造后新出现的地形景观称为地震断错地貌。地震断错地貌可分为地震断层崖、地震断错——挠曲崖、地震断错水系和地震断错台地四类。研究地震断错的相关堆积时,发现逆推断层崖也有崩积楔。提出的崩积楔发育模式与正断层崖的发育模式截然不同。

| Abstract: | The dislocation, generated by large earthquake, may cause the surface feature changed from its original state. This new geomorphologic landscape formed after the dislocation is called earthquake dislocation geomorphy,which can be divided into four types in detail;earthquake fault scarp, earthquake dislocation-flexural scarp, earthquake offset drainage system and earthquake offset platform. We also found colluvial wedge on the reversed fault when studying the correlative accumulation of earthquake dislocation, but the developing model of colluvial wedge is quite different from that of the one generated on normal fault scarp. |
