摘要
通过对藻煤、烛煤、腐殖煤共生煤层的分析，将不同成因类型煤中的烷基环己烷和烷基苯进行了比较。结果表明，不同成因类型煤中所含的烷基环己烷和烷基苯明显不同。各种成因类型煤中烷基环己烷和烷基苯所提供的母质信息与煤岩结果吻合。氧化环境不利于烷基环己烷和烷基苯的形成。烷基环己烷和烷基苯有时可以作为沉积环境和成熟度的标志。
According to the study of microscopic deterrnination,colorimeter and gas chromatography mass spectrography computer analysis of the intergrown boghead coai,can-nel coal and humic coal from shanxi.the results show that cvclohexanes and alkvlbenzenes are obviously different in coals of different genetic types.The information of matrix,by or-ganic geochemical character of coals are identical with the resuIts of coal petrological study.Cyclohexanes and Alkylbenzenes are rarely formed in oxidizing milieu. And they may consti-tute a molecular,fingerprint’which can be of value in inferring the environment or maturi-ties.
