在与国际上同期海相地层锶同位素演化曲线对比的基础上，研究了晚白垩世海相碳酸盐锶同位素组成与主要地质事件的关系；在将本研究锶同位素数据融入到全球中新代海水锶同位素曲线的基础上，综合作出了中新生代海平面变化和锶同位素对照曲线，讨论了全球风化速率，造山事件，气候，海平面变化以及灾变性事件对中新生代海水锶同位素的控制作用；根据锶同位素地层学原理，本研究尝试将碳酸盐锶同位素组成用于海相地层定年上，利用已有的全球海水87Sr/86Sr值-年龄数据库和测试的藏南晚白垩海相碳酸盐的87Sr/86Sr值，确定了岗巴剖面Campanian/Santonian和Maastrichtian/Campanian阶界线，标定了广泛分布于白垩纪的厚壳蛤化石的年龄；本研究还将这些方法推广到了塔里木盆地井下奥陶纪地层的年龄标定，确定了中/上，中/下奥陶统界线，从锶同位素角度获得了古岩溶作用证据，显示锶同位素地层学在解决海相地层对比，年龄确定及在岩溶型油气储层研究中的潜在价值和良好应用前景。

The Lower/Upper Cretaceous boundary in Songliao Basin is,therefore,between the Quantou and Denglouku formations,instead of between the Quantou and Qingshankou formations.2.The dark mudstones and shales in the Member 1 of Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characters are illustrated by biomarkers of 28,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of Qingshankou Formation are the products of lake anoxic period.It corresponds to the oceanic anoxic event at Cenomanian-Turonian boundary in Cretaceous.3.Based on the study of biostratigraphy,chronostratigraphy,magnetostratigraphy and event stratigraphy,a correlation of the lacustrine sequence to marine standard has been proposed,i.e.,the Quantou Formation corresponds to Cenomanian stage,Qingshankou Formation correlates to Later Cenomanian-Early Turonian,Yaojia Formation to Later Turonian-Coniacian,Nenjiang Formation to Santonian-Campanian.Sifangtai and Minshui Formations to Maastrichtian. 4.Analysis of lithology,lithofacies and microfossils of Cretaceous in Songliao Basin, shows that shore and shallow lake facies yield the most abundant microfossil groups,and the predelta and deltaic distributary plain facies rich in fossils as well.In the shore and shallow lake areas during the high level periods(such as Qingshankou and Nenjiang sedimentary periods),the lacustrine biota are of high diversity and high abundance.

因此，松辽盆地上、下白垩统的界线应在泉头组的底界，即泉头组与登娄库组之间，而不是泉头组的顶界。2、青山口组一段黑色泥岩、页岩具有有机碳含量高、重排甾烷含量低，生物标志物出现28，30—双降藿烷和伽马蜡烷，干酷根碳同位素具有正向偏移等有机地球化学特征，表征为青山口组一段黑色页岩、油页岩是古湖泊缺氧事件的产物，它对应于白垩纪古海洋Cenomanian—Turonian期界线附近缺氧事件，二者具同步性。3、通过生物地层学、年代地层学、磁性地层学和事件地层学研究，认为泉头阶大体相当于Cenomanian阶，青山口阶相当于晚Cenomanian—早Turonian阶，姚家阶对应于晚Turonian—Coniacian阶，嫩江阶对应于Santonian—Campanian阶，四方台阶和明水阶相当于Maastrichtian阶。4、通过对松辽盆地上白垩统的岩性、岩相及微体化石分析，认为滨浅湖相是微体生物群最为发育的相带，其次为三角洲前缘相和三角洲分流平原相。
