首次对羌塘盆地上三叠统土门格拉组烃源岩生物标志化合物特征进行了研究，揭示了生物标志化合物对该地区有机质生源构成、沉积环境和成熟度的指示意义。研究结果表明：土门格拉组烃源岩中的有机母质为混合来源，既有陆生植物来源，又有低等水生生物来源，烃源岩的沉积环境为具有一定盐度的还原环境。烃源岩成熟度参数显示，土门格拉组烃源岩有机质演化程度已达到高成熟阶段。生物标志化合物的这些特征进一步证实了土门格拉组烃源岩具有较好的生烃潜力。

This paper firstly reported the study on biomarkers' characteristics of the Upper Triassic Tumengela Formation in Qiangtang Basin.Some typical biomarkers can be used to determine the biologic source nature and maturity of the organic material,and the depositional environment.The result reveals that the main sources of the organic matters are mixed sources,which originated from high-grade plants and algaes and bacteria.Some of the biomarkers indicate that the sedimentary environment of source rocks is a reducing environment with certain salinity.The maturity parameters of source rock indicate that the degree of maturity of organic matter is high. The above characteristics of biomarkers of source rocks in the Tumengela Formation further confirmed that the formation has good hydrocarbon potential.
