摘　　要：地震是一种常见的自然现象,当震级大于5级的震区可能形成震积岩。震积岩顾名思义为地震诱发沉积物的变形、再沉积的局域性的特殊地质体。不同的区域活动背景也会发育不同的沉积构造,海相与陆相震积岩的水下模式有着一定的相似之处。本文在前人研究基础之上总结并对比了陆相震积岩与海相震积岩的识别特征及其异同。Earthquske is a common natural phenomenon. And it might be formed seismites when the magnitude of earthquake region greater than 5. As the name suggests, seismites is a local specific geological body with sediment deformation and Re-deposition induced by earthquake. Different sedimentary structures are developed in different regional tectonic background. There are some similarities between the underwater model of terrestrial and marine seismites. Based on previous studies, this paper summarizes and compares the characteristic and the similarities and differences between terrestrial-seismites and marine-seismites.
