以一种类似地层中无孔多胞孢的现代真菌链格孢属孢子为样品，研究真菌孢子的原生烃烷烃馏分生物标志物及其热解生烃特征。实验结果表明，真菌孢子样品原生烃类的烷烃馏分，主要由正烷烃、异构烷烃和链烯烃组成。正烷烃约占抽提物总量的０．１８％。ｎＣ１９，烷占正烷烃总量的２４．１％。链烯烃组分约相当于正烷烃总量的４８．５％。异构烷烃总量约相当于正烷烃总量的７０．２％。真菌孢子热解生烃也以低碳数烃类为主。在未—低成熟阶段，真菌孢子热解生烃以富含Ｃ１７二环萜烷和Ｃ２８甾二烯为特征。在正常成熟阶段，真菌孢子热解生烃以ｎＣ１５烷为主峰碳及甾烷Ｃ１９／（Ｃ２７＋Ｃ２８＋Ｃ２９）比值在０．５左右为特征。
A similar genus of non-porous polysosporium Alternaria spores of fungi as a sample fungi spores of crude paraffins biomarkers and their pyrolysis hydrocarbon generation characteristics. The experimental results show that the paraffin fraction of primary spores of fungal spore samples mainly consists of n-alkanes, isoparaffins and alkenes. Normal alkanes make up about 0.18% of the total amount of the extract. nC19, alkane accounted for 24.1% of the total amount of n-alkanes. The alkene component corresponds to about 48.5% of the total amount of n-alkane. The total amount of isoparaffins is about 70.2% of the total amount of n-alkanes. Pyrolysis of fungal spores hydrocarbon also low-carbon-based. In the non-low maturity stage, pyrolysis of fungal spores is characterized by the enrichment of C17 dicyclo- and C28-steroidal dienes. During the normal maturation stage, pyrolysis of fungal spores is dominated by the predominant peak carbon of nC15 and the C19 / (C27 + C28 + C29) ratio of about 0.5.
