Abstract
Middle Triassic marine sediments in the Baise Basin are characterised by stable carbon isotopic δC-value of -27.49-29.34‰, Pr/Ph less than 0.5 and the presence of garmmacerane, tricyclic terpanes, β-and γ-carotanes. Middle Triassic biomarker distribution reflects saline and strong reducing palaeoenvironment. The stable carbon isotopic δC-value and biomarker data indicate that Middle Triassic oils come from the source rocks of the Tertiary Nadu Formation. The Middle Triassic strata, having very low abundance of organic matter, belong to nonsource rocks and are inmature to condensate stages.
