摘　　要：松辽盆地白垩纪地层分布广,沉积厚度大,地层发育齐全。以三大生物群中最具时代意义的重要化石为出发点,结合近年来盆地内火山岩、火山碎屑岩同位素地层研究成果,对松辽盆地白垩纪年代地层学进行系统的研究,进而对确定松辽盆地沉积盖层的地质时代的归属有一定的借鉴意义。Cretaceous strata in Song-Liao basin were widely distributed with large sedimentary thickness,stratigraphic development were complete.In this paper,we started form the most time-meaningful fossil in three major biota,combined with the recent research results of volcanic rocks and volcaniclastic rocks isotopic strata we studied the chronostratigraphy of Song-Liao basin Systematically,and then we made a certain significance to identify the geological age ownership of the sedimentary cover in Song-Liao basin.
