本文研究了长尾复叶耳蕨孢子原生烃类及其热演化试验产烃的烷烃生物标志物分布特征。结果表明蕨类孢子生烃在未成熟－成熟阶段以高碳数烃类为主，在高－过成熟阶段以低碳数烃类为主。花侧柏烯和丰富的Ｃ３０藿烯、蕨烯是蕨类孢子原生烃及其未成熟阶段生烃的重要特征．蕨类孢子生烃的甾烷Ｃ２９／Ｃ２７＋Ｃ２８＋Ｃ２９比值＞０．５，Ｃ２７／Ｃ２７＋Ｃ２８＋Ｃ２９比值＜０．２，显示很强的陆源特征。实验结果还表明，由于孢子生物有机化学成分热稳定性不一致，因而孢子生烃具有阶段性。
In this paper, the distribution characteristics of alkanes biomarker for the production of hydrocarbons from Protoceraspora protothecoides and their thermal evolution tests were studied. The results showed that the genera of fern spores were mainly high-carbon hydrocarbons in the immature-mature stage and low-carbon hydrocarbons in the high-over-mature stage. Flosythiotene and abundant C30 Hatchpene, fern is fern spore primary hydrocarbon and its immature stage, an important feature of hydrocarbon generation. The stomatal C29 / C27 + C28 + C29 ratio of ferment spores> 0.5 and the ratio of C27 / C27 + C28 + C29 <0.2, showing strong terrestrial characteristics. The experimental results also show that due to the thermal stability of spores bioorganic chemical composition is inconsistent, so spores hydrocarbon generation has a stage.
