摘要：

震积岩是具有特殊震积构造和震积序列的一种灾变性事件岩。通过岩心观察和描述, 在阳信洼陷古近系陆源碎屑断陷湖盆砂泥质沉积地层中识别出大量具有震积岩特征的变形构造, 如微断层和震裂缝、水下岩脉和泄水构造、振动液化卷曲变形构造、震积枕状层及伴生构造等, 同时建立了阳信洼陷震积岩垂向序列, 自下而上分别是下伏未震层段、微断层层段、震碎角砾岩段、振动液化卷曲变形层段、震积砂枕及伴生构造层段、液化均一层段和上覆未震层段。不同的震积岩构造特征对应不同的地震强度, 震积岩的发现不但有助于分析判断控盆边界断裂的强烈活动时期, 震积岩自身也可能是一种潜在的油气储集体, 因而研究地震事件沉积具有重要的地质意义。

Abstract:

Seismite is a type of catastrophic deposits with recognizable evidence for seismic activities and sequence. According to core observation and description, many deformation structures with seismite characteristics are recognized within sandstone and shale sedimentary strata of Paleogene continental faulted basin in Yangxin Subsag, such as micro-faults, earthquake fissures, liquefaction sandstone veins, water-escape structure, vibrational liquefaction deformation structure, seismic pillow structure and associated structure, etc. The vertical sequence of seismites in Yangxin Subsag, in ascending order, is underlying unshocked layer, micro-faults layer, autoclastic shattered breccia layer, vibrational liquefaction deformation structure layer, seismic pillow structure and associated structure layer, liquefied homogeneous layer and overlying unshocked layer, which corresponds to different earthquake intensity respectively. The discovery of seismites can be used to analyze the intensive activity stages of basincontrolling boundary fault, and seismite itself is a kind of potential reservoir, so it has important geological significance for studying earthquake event deposit.
