| 摘 要： | 地震事件沉积(震积岩)是现代沉积学的一个热点问题。地震可引发各种软沉积物变形,容易造成地震成因的和非地震成因的软沉积物变形的混淆。论文重点讨论了地震成因和非地震成因(冰融作用,天然气水合物泄漏,水力破裂,滑坡、滑塌、泥石流,液化等)的软沉积物变形,并对地震同生、准同生软沉积物变形及其与相关的软沉积物变形关系进行了讨论。

| Abstract: | Earthquake event deposit(seismites)is a “hot spot”in modern sedimentary geological study. Earthquake-caused soft-sediment deformations are easily confused with non-earthquake-caused soft-sediment deformations. This paper discusses earthquake-caused and non-earthquake-caused (ice melting process,natural gas hydrate leakage,hydrofracturing,slide,slump,debris flow,liquefiedsoft-sediment deformations) soft-sediment deformations and relationship between synsedimentary,penecontemporaneous earthquake-caused and non-earthquake-caused soft-sediment deformations. |

| Keywords: | soft-sediment deformation structure earthquake event deposit seismite |
