| 摘 要： | 采用煤岩学和有机地球化学相结合的方法对比分析了镜煤和亮煤的生烃潜力，并根据分子化石探讨了它们的形成环境。研究结果表明，亮煤的生烃潜力大于钻进，其形成时泥炭沼泽内的覆水程度、还原程度和凝胶化程度都高于镜进，且它们的水介质ｐＨ值也可能有较大差异。

| Abstract: | The hydrocarbon-generating potential of vitratn and clarain is studied by the means of coalPetrology and organic geochemistry,and their geological origins are also discussed with their molecular foSSils. Asa result,the clarain's potential of preducing hydrocarbon is superior to the vitrain's,and the groundwater level,the degrees of reduction and gelification in the Peat swamp in which the clarain deposited are respectively higherthan those of the vitrain swamp.In addition,the acidity degrees in theie swamp water are also somehow differentduring their dePOSition. |
