摘要: 本文运用有机地球化学测试手段,对东柏各庄凸起侏罗系烃源岩(泥岩、煤)氯仿抽提物的烃类组成进行了系统剖析,揭示其具有煤系地层的地化特征,系成熟的烃源岩,在饱和烃镏分中发现-不常见的苯基烷烃化合物系列,可能系微生物藻类成因.

Abstract: The hydrocarbons in the chloroform extract of Jurassic source rocks(mudstone,coal)in the Baigezhuang Uplift of East Hebei province have been analysed systematically by means of organic geochem ical measurements.It is revealed that the source rocks have the geochemical characteristics of coal-measure strata and belong to mature hydrocarbon source rocks.An unusual compound series-alkyl benzene dis covered in the fraction of saturated hydrocarbons is probably from microbial and algal origin.
