| 摘 要： | 古地震是依据地层中保留的沉积物变形记录而确定的。系统归纳总结地震诱发沉积物变形将为古地震研究提供理论基础，也有助于野外调查辨认这些记录。作者提出了一个初步的、供讨论与补充修正的地震触发沉积物变形分类的方案。变形的成因机制是分类的基础。这些特殊沉积物变形主要与地震有关，但其中一些变形往往也受其他多种因素的影响，因此要确定地震成因变形必须详尽研究相关的区域地质背景构造。

| Abstract: | Ancient earthquake are determined by various sediment deformation structures contained in the strata.The systematic induction and summarization of the sediment deformation produced by earthquakes will provide the theoretical basis for ancient seismite researches,and is helpful for recognizing those signs in the field.The classification of sediment deformation brought by earthquakes introduced here is a draft to be discussed,supplemented and revised.The genesis mechanism is the bedrock of classification.Thou... |
