羌塘盆地上三叠统土门格拉组烃源岩生物标志物地球化学特征
Geochemical Characteristics of Biomarkers of the Upper Triassic Source Rocks from Tumengela Formation in Qiangtang Basin of Tibet
摘要
Abstract
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.关键词
