渤海海域石臼坨地区古近系沙河街组湖相生屑白云岩成因OA北大核心CSCDCSTPCD
Origin of lacustrine bioclastic dolostone in the Paleogene Shahejie Formation: A case study in Shijiutuo area, Bohai Sea
渤海海域石臼坨地区石臼坨凸起东倾末端南北两侧的陡坡带在古近系沙河街组发育多套生屑白云岩,其中南侧生屑白云岩主要发育在沙河街组二段,北侧生屑白云岩集中在沙河街组一段.为了明确该区生屑白云岩的成因,通过古生物、岩石薄片和地球化学等资料对该区生屑自云岩的岩石学、地球化学特征进行较为系统的研究.按照岩石组分特征,研究区生屑白云岩可划分为亮晶生屑白云岩和泥晶生屑白云岩2种类型.生屑的主要组分腹足类及介形类典型属种分析显示,南北两侧生屑自云岩均形成于浅水湖泊…查看全部>>
There are several sets of bioclastic dolostone in the Paleogene Shahejie Formation on the north and south of the eastern margin of Shijiutuo uplift,Shijiutuo area,Bohai Sea.The bioclastic dolostone on the south of the eastern margin of Shijiutuo uplift is mainly developed in the Member 2 of Shahejie Formation,while that on the north is mainly developed in the Member 1 of Shahejie Formation.Based on paleontology,thin sections,geochemical data,the petrological…查看全部>>
