The Features of Seismite in Jiyang Sub-Basin,Paleogene

University of Petroleum,Dongying Shandong 257061

摘要: 通过岩芯观察和描述,在济阳坳陷古近系沙河街组沙四段上部和沙三段地层中识别出震积岩。震积岩的主要标志是发育各种类型的软沉积变形构造,包括小规模阶梯状正断层、层内小褶皱、扭曲变形、振动液化砂岩脉、微裂缝、震碎角砾岩、火焰构造等。各凹陷的北部陡坡带的沙三段震积岩较发育,沙四段上部次之。凹陷的不同位置,震积岩的序列有所不同,远离控盆边界断裂,震积岩序列的完整性变差,这反映出震积岩是由控盆边界断裂强烈活动引发的地震所产生的直接结果。震积岩在地层剖面中多次出现表明边界断裂的活动具有周期性和幕式特点。这一成果为陆相断陷湖盆构造演化研究及震积岩的识别和描述提供了重要的地质理论依据。

Abstract: By the observation of drillng cores, the seismite is recognized which mainly occurredin the upper part of Member4 and Member 3 of Shahejie Formation inthe Lower Tertiary in Jiyang sub-basin. Many kinds of soft sedimentarydeformation structures have been found in seismite, such as step micro-faults, pleatedwithin layers,liquefactionsandstone and clay veins, vibrationalliquefaction deformation structure, seismic breccias and flame structure. Seismites mainly occur in the northern steep zoneof rift lacustrine basin. There develop more seismites in Member 3 than in the upper part of Member4. Away from the basin-controlling boundary fault, the sedimentary sequence integrity of seismites gets worse. This reflects that seismites are the direct resultsof earthquake which causedby the intenseactionof basin-controlling boundary fault .The repeated emergence of seismites in stratasection showsthat themovement of boundary faultshas periodicity and episodicity. The researchprovides theoretical foundation for the tectonic evolution studies and seismite recognization in continental rift lacustrine basin.
