摘　　要：运用有机岩石学和有机地球化学理论对新疆侏罗系煤中基质镜质体的岩石学特征及生烃性进行了详细研究，结果表明，基质镜质体按成因和生烃性可分成三种不同的亚型，并讨论了不同类型的基质镜质体在煤成烃作用中的意义和热演化规律。Applying the theories of organic petrology and organic geochemistry,the petrographic characteristics of desmocollinite in Jurassic coals in North China and the hydrocarbon generating nature are studied in detail.The research results indicate that the desmocollinite can be divided into three subtypes according to the genesis and hydrocarbon generating nature.The significance of desmocollinites of different subtypes in the generation and thermal evolution regularity of coal derived hydrocarbon and discussed.
