几种常见震积岩相标志在模拟实验中的识别

震积岩相标志是识别震积岩的最有效依据。在对震浊积岩形成过程的水槽模拟实验中，发现了同沉积断裂、微褶皱纹理、液化砂岩脉、液化均一层、同沉积变形构造、震浊积岩等典型的软沉积物震积岩相标志，他们形成于地震作用的不同阶段，有规律的分布在三角洲—震浊积岩体系之中。同时，模拟实验中也发现了一些与震积岩相标志易混淆的其他成因相标志，因此在分析过程中应该充分考虑各种相标志的组合特征、与沉积环境的配置关系以及区域的构造背景等。依据模拟实验得出的震积岩相标志分布模式，通过相标志类型和组合特征分析，可进行震浊积体发育区带预测，指导断陷盆地隐蔽油气藏勘探。

Identification of Common Facies Indicators of Seismites in Simulated Experiments

Sedimentary facies indicators are the best effective criteria to identify seismites.In the flume experiments to simulate seismo-turbidites,several typical facies indicators of seismites are found in soft sediments,such as synsedimentary faulting,microcorrugation,liquefied sandstone dike,liquefied uniform bed,syndepositional deformation,seismo-turbidites,and so on.They formed in different periods of seismism and distribute regularly in the system of delta to seismo-turbidites.At the same time,some facies ind...
