摘要
在系统总结古生物资料的基础上,结合区域岩石地层分布情况及近年来同位素测年资料,得出如下结论:阜新组中下部(高德层-孙家湾层)可与营城组对比,时代为巴列姆期—阿普特期;阜新组上部(水泉层)可与登楼库组下部(一、二段)对比,时代为阿普特期;登楼库组上部(三、四段)与阜新组顶部火山岩(张老公屯组)层位相当,时代为阿普特期—阿尔布期.
Based on the stratigraphic distribution, biostratigraphy and in Western Liaoning with Yingcheng and Denglouku formations in the isotopic ages, the authors correlate Fuxin formation Songliao Basin. Fossil assemblage indicates that the Yingcheng formation may correlate with the middle and lower part of the Fuxin formation, while the lower part of the Denglouku formation is equivalent to the upper part of the Fuxin formation. The upper part of Denglouku formation may correlate with the top of the Fuxin formation （Zhanglaogongtun formation） according to stratigraphic distribution, fossil assemblage and isotopic dating of volcanic rocks.
