摘要
通过对金沙江中段震积岩的研究，建立了大陆边缘震积岩序列。该序列包括递交断裂层、震碎角砾岩、震褶岩及层内断层、滑塌巨角砾岩、震积角砾岩及震浊积单元，它具有原地相的地震扰动层和异地相的滑来震积层双层结构，两层之间被震积不整合面所分隔。该序列反映了一次地震事件的全过程，将为地质学家识别大陆边缘地震事件提供对比标准。
A new seismite sequence in continental margin is established by authors studying the seismites in the middle region of the Jinsha River.This sequence consists of a series of units, such as graded fault bed,seismic breccia, seismic corrugated rock and ladder fault,slip megabreccia,seismobreccia and. seismoturbidite.The seismites are composed of twolayer structures:the seismodisturbed beds of dominate factes and the slumping seismites of heterochthonous factes. This two layers contact with seismodisconformity surface.
