CORRELATION BETWEEN FUXIN FORMATION IN WESTERN LIAONING AND YINGCHENG AND DENGLOUKU FORMATIONS IN THE SONGLIAO BASIN

Based on the stratigraphic distribution, biostratigraphy and isotopic ages, the authors correlate Fuxin formation in Western Liaoning with Yingcheng and Denglouku formations in the 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.
