摘　　要：应用煤岩学对强还原型腐殖煤系列样品(R_0=0.55％～1.01％)研究表明,它们含有较多的镜质组—类脂组过渡显微组分,这种组分的特征是:比基质镜质体反射率低,但荧光强度和生烃潜能较高。据显微特征可将其分为两种亚型——交织型和膨融型。它是荧光基质镜质体的另一种表现形式和强还原型腐殖煤生油的主要母质之一。Study of a series of strong—reductivity humic coals of 0.55 to 1.0 in rank by coal petrologictechnique reveals that they contain high proportion of vitrinite—liptinite transition maceral.The properties of thistransition maceral is that it has relatively lower reflectance and stronger fluorescence,and higher oil potentialthan normal desmocollinite.Based on its microcharactors,this transition maceral may be devided into two maceraltypes——intertexture type and swelling type.This transition macerals is the orther form of expression of fluore-cent desmocollinite,and one of the principal parent substance of strong—reductivity humic coal—formed oil.
