本文研究结果表明阜新煤田主要煤层煤中丝炭主要是氧化成因，而镜煤则形成于相对还原环 境。成煤环境中的氧化还原条件对镜煤和丝炭各自有机地球化学特征和产烃潜力均有重要的影 响。镜煤和丝炭热解产烃潜力差别很大，但热解过程中产生的烃类的成分组成十分相似，都是以 气态烃为主，其中甲烷含量占８５％以上。因此，这一实验结果证明镜煤和丝炭主要是生气母质而 不是生油母质。
The results of this paper show that the main coal in the coal of Fuxin coalfield is mainly oxidized, while the mirror coal is formed in the relative reduction environment. The redox conditions in a coal-forming environment have important implications for the organic geochemical characteristics and hydrocarbon-producing potentials of the metallurgical coal and the silks, respectively. The potentials for the hydrocarbon production from pyrolytic mirroring and silk pyrolysis differ greatly, but the composition of the hydrocarbons produced during the pyrolysis is very similar, with gaseous hydrocarbons predominated, with methane content above 85%. Therefore, the results of this experiment show that vitrinite and charcoal are mainly gasogenic rather than gasogenic.
