摘要：

震积岩(物)是地史时期地震事件的岩石学记录,其震积层序自下而上由微型递变断裂层、微褶皱层、碎块层和液化均一层组成。震积岩可作为古地震计,以了解地史时期地震的时空分布、地震强度和迁移规律。以作者发现的峨眉震积岩为例,描述了震积层序中的各种特征,总结了认识和辨别震积岩的标志。

关键词: 震积岩, 震积层序, 微断裂层, 微褶皱层, 碎块层, 液化均一层

Abstract:

Seismite is a petrological record of seism event in geologic history. From the bottom to top, the seismite sequence is composed of microfault bed, rubble bed and homogeneous bed. As a peleo-seisometer. The seismite can be used to understand seismicity and migrating laws of seism in geologic history.As a living example of seismite the authors discovered in Emei Mountain, authors have described various characteristics and summarized the marks of seismites.

Key words: Seismite, Seismite sequence, Microfault bed, Microtold bed, Rubble bed, Homogeneous bed
