Issue:S1 Journal:Acta Sedimentologica Sinica Keyword:Biyang Depression; lacustrine facies; carbonate rocks; oil-source rock correlation; Abstract:The general characteristics of lacustrine carbonate source rocks are discussed in this paper,where the lacustrine carbonate of Hetaoyuan Formation,Tertiary,Biyang Depression,was taken as an example.That the composition characteristics,the contents of organic matters,the transformative rate of hydrocarbons and the type of organic matters show that lacustrine carbonate source rocks are rich in oil-generating material,and the convincible oil-source rock correlation material indicates that lacustrine carbonates not only can generate oils,but also be the source rocks of commercial oils.
