THE CRETACEOUS SPORO-POLLEN ASSEMBLAGE IN SONGLIAO BASIN AND ITS PETROLEUM-STRATIGRAPHICAL SIGNIFICANCE
-
摘要: 松辽盆地是我国东北部最大的中新生代沉积盆地,沉积了自晚侏罗世以来的所有地层,其中尤以白垩系发育最全,厚度最大,分布最广,古生物化石亦最为丰富,而且蕴藏着丰富的石油资源。因此许多学者及单位,从不同的角度进行了大量的工作和研究。目前尽管对各组的时代归属尚有分歧意见,但对其层序及划分意见基本统一,即自下而上为:登娄库组——泉头组——青山口组——姚家组——嫩江组——四方台组——明水组。Abstract: According to the existing data of Songliao Basin and from the aspects of petroleum geology, a discussion is made on the Cretaceous sedimentation environment of Songliao Basin and its relation with oil-bearing strata, and the formation of source material by using the dependence of sporo-pollen fossil assemblage on the Cretaceous sedimentation environment. This paper contains three parts. (1) Brief description of the strata and the sporo-pollen fossil assemblage; (2) Discussion on the paleoclimate and paleovegetation of the stage of sedimentation; (3) Variation of Cretaceous paleogeography and paleoclimate in the Songliao Basin and its relation with the formation of source ma-terial.
