震积岩、海啸岩、震浊积岩研究进展

Advances in Research for Seismite, Tsunamite and Seismoturbidite

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。近十几年来国内外许多学者在研究、对比现代和古代震积岩成因沉积物后,逐渐认识到震积岩不同于其他类型的沉积岩。国内外学者对震积岩的研究主要集中在古生代以前的海相地层,本文从震积岩特征及其地质意义介绍了震积岩的岩石类型、震积序列、鉴别标志及震积岩,海啸岩,震浊积岩的对比鉴别。震积岩自身也是一种潜在的油气储集体,通过对震积岩的研究还可以更多地了解古代地震发生的规律,为预测地震活动等提供有利证据。

Seismite is a rock type due to seism as a catastropic event. It has a special seismitic structure and seismitic sequence which differs from other sedimentary rock types. This paper deals with rock type, seismitic sequence and diagnostic property of seismite as well as correlation of seismite, tsunamite and seismoturbidite. The seismite is a potential reservoir. Study of seismite can understand law of old earthquakes which provides useful information for prediction of earthquake.
