通过分析采集自甘肃窑街中侏罗统的炭质泥岩、油页岩、泥岩中的饱和烃馏分和芳烃馏分以及裸子植物化石角质层中的相同组分,在样品中检测出表征高等植物输入的生物标志化合物,表明裸子植物角质层为烃源岩生物标志化合物的母源之一.结合藿烷母质类型等参数的分析,表明烃源岩样品以高等植物输入为主,且水生藻类有一定贡献.植物化石角质层样和烃源岩样中表征细菌微生物作用、指示沉积环境以及判断样品成熟度的参数均吻合,说明窑街盆地中侏罗统的沉积相属于弱氧化-弱还原的半深湖相或滨浅湖相,沉积介质为淡水-微咸水,有机质经历过一定程度的微生物降解作用,处于未熟-低熟阶段.研究结果对深入分析窑街盆地中侏罗统烃源岩沉积环境具有指导意义. By analyzing the same components in the carbonaceous mudstone, oil shale, mudstone, and middle-Jurassic collected from the kiln street in Gansu Province, the same components in the aromatic fraction and the stratum corneum of the gymnosperm fossils were detected in the samples for characterization of higher plant inputs Biomarker compounds, indicating that the stratum corneum of gymnosperm is one of the sources of biomarkers of source rocks.Based on the analysis of the parameters of hopane type and other parameters, it indicates that the source rock samples are mainly imported from higher plants and the aquatic algae have a certain contribution The fossil horny stratum samples and source rock samples showed the role of bacterial microorganisms, indicating the sedimentary environment and the parameters of sample maturity, which indicated that the Middle Jurassic sediments in Yaojie Basin belonged to the semi-deep of weak oxidation-weakening Lacustrine or shore-shallow lacustrine facies, the sedimentary medium is freshwater-brackish water, and the organic matter has undergone a certain degree of microbial degradation and is in the immature-low maturity stage. Environment is instructive.
