地震和非地震引发的软沉积物变形

摘要

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-sedi-ment deformations)soft-sediment deformations and relationship between synsedimentary,penecontempora-neous earthquake-caused and non-earthquake-caused soft-sediment deformations.%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。
