In this area seven microfacies in the Chuangde Fm. red beds can be separated. They are: 1 reddish foraminifera grainstone; 2 reddish microfossils packstone/wackestone; 3 reddish marlstone with microfossils; 4 reddish marlstone; 5 red to variegated floatstone ; 6 reddish shales; 7 reddish radiolarite/ radiolarian chert.In the Yamudok Cuo area, it can be distinguished six microfacies in the redbeds including 1 reddish foraminifera grainstone; 2 reddish microfossils marlstone; 3 reddish shales; 4 yellow-grayish floatstone ; 5 reddish radiolarian chert; 6 reddish chert with radiolaria. The depositional environment of the Chuangde formation can be interpreted from sediments composition, as is deep oceanic basin adjacent to continental slope/rise. The slope/rise setting is indicated by the occurrence of olistoliths and slumped pelagic/hemipelagic limestone, present near the top of the Chuangde Fm.

An apparent negative excursion at bed 22 is correlated with the globaltemperature decline. The ~(87)Sr/~(86)Sr ratio of 0.707605 can be related to the tectonic processand sea level rising resulting from the rapid Indian Ocean ridge expansion in Campanian.Decrease of detrital weathering materials is resulted from ingression.
在第22层位上,锶同位素曲线出现一处明显的负偏波谷,~(87)Sr/~(86)Sr比值达到了0.707605,此时全球温度也出现下降,对应坎潘期印度洋脊南北向迅速扩张,全球海平面上升,大规模海泛导致盆地中陆地剥蚀物减少。

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。
