松辽盆地营城组火山岩旋回和期次划分——以盆缘剖面和盆内钻井为例
|
摘要
松辽盆地营城组火山岩具有多期次、间歇性喷发特征。松辽盆地营城组火山岩研究采用旋回(对应于火山机构)-期次(对应于岩相组合)-岩相(对应于特定喷发方式及其产物)三级划分方案。期次是指一个喷发中心一次相对集中的(准连续)火山活动,在物质成分、喷发方式及喷发强度的规律性变化过程中,所形成的一套相序上具有成因联系的岩石组合。旋回由一个至若干个期次构成。在期次划分过程中,综合运用了地质方法与地球物理方法,充分利用岩性、岩相、测井和地震资料,依据相关地质界面,并与火山机构分析相互结合。据此将营城组建组次层型实测剖面划分为5个旋回,13个期次。
The volcanic rocks of the Yingcheng Formation in the Songliao Basin were formed by multiple and intermittent eruptions.Triple division was applied in the basin volcanic rocks researches: volcanic cycle,stage and facies.A volcanic stage was defined as volcanic rock assemblages formed by a concentrated volcanic activity at certain eruption center during its regular changes on materials,components,eruption behaviors and intensity.And a volcanic cycle includes one or several stages.Geological and geophysical methods were used to divide volcanic stages,including volcanic lithology and facies ana-lysis from logging and seismic information.Special geological interfaces were identified.The measured section of the Yingcheng Formation has been divided into five volcanic cycles and thirteen stages.
