| 摘 要： | 中国泥盆纪煤是形成于特定地质历史条件的特种煤，因而具有独特的地球化学特征：显微组成以富含角质体为特征；可溶有机质含量高于泥岩，低于正常腐植煤；芳烃中含丰富的多环芳烃，并检测出芳香倍半萜和芳香二萜及芳香断藿烷；热模拟表明角质体在R0达到0．95％时达到生烃高峰；丰富的四环二萜化合物随成熟度增加，由环状化合物裂解为链状烷烃。

| Abstract: | Chinese Devonian coal is a special kind of coal formed under a given geohistorical condition, with the result of particular geochemical characteristics. Its maceral is specified by rich cutinite; soluble organic matter content higher than it is in mudstones, but lower than in normal humic coal; abundant muhiring hydrocarbon in aromatic hydrocarbon, and aromatic sesquiterpene, aromatic diterpene and aromatic stopped hopane were detected; heat simulation indicated that the peak of hydrocarbon generation is when Ro reached to 0.95%; abundant tetracyclic diterpane compounds increasing along with the maturity, splitting from cyclic compounds into paraffinic hydrocarbons. |
