摘要
伊通盆地岔路河断陷属于伸展断陷盆地,由于其复杂的构造作用、独特的几何形态、多物源供应、具多个沉积沉降中心以及侧向相变快的特点,给地层划分和对比带来了很大的困难。利用钻井岩性、地球物理、古生物资料,运用层序地层学研究方法对岔路河断陷始新统地层进行了划分对比。结果显示,岔路河断陷始新统地层由老到新划分为双阳组、奢岭组和永吉组,指出了相应的地层划分和对比依据,并与渤海湾盆地进行了古生物化石地层对比,阐述了二者在成因上可能存在的关系。
Abstract
The Caluhe Depression of the Yitong Basin is a extension rift basin,due to the complex tectonics,particular morphology,sedimentary source from several directions,several depocenter and subsidence center and the rapid facies transition,there is much difficulty in the stratigraphic division and correlation.Based on the data of predecessor research,involved some methods and data of well lithology,geophysical,paleontology,combined with sequence stratigraphy,this paper deals with the Eocene stratigraphic division and correlation of the Chaluhe Depression in the Yitong Basin.It is suggest that Eo-cene is made of the Shuangyang Formation,the Shelin Formation and the Yongji Formation,and indicate the evidences of strata division and correlated,and analysis the correlation between the Yitong Basin and the Bohai Bay Basin.
