Biomarker Assemblage Characteristics of Source Rocks and Associated Crude Oils in Saline Lake Facies of Cenozoic in China

Zhang Zhihuan; Yang Fan; Li Dongming; Fang Zhaoliang

Saline lakes of Cenozoic are extensively developed in China. There are unique sedimentary environ-ment and condition of hydrocarbon generation in these saline lakes. The geochemical charactristics of source rocks and hydrocarbons generated rom saline lakes sedimentary environment are different to those generated from f reshw ater lacustrine facies and those generated from marine facies. Is is all intro-duce that biomarker assemblage characterisitics, generating condition and geochemical significance of source rocks and crude oils in saline lakes.
