| 摘 要： | 中国华北盆地晚古生代煤系太原组(C_3)强还原型煤(煤相Ⅰ和煤相Ⅱ)与热史相近的山西组(P_1~1)弱还原型煤(煤相Ⅲ)相比,其反射率存在着明显的抑制作用(Suppression)。应用有机岩石学、有机地球化学和荧光光度学等参数相结合的方法,着重讨论了这种抑制效应及其产生的原因,并提出了富氢镜质体及由其组成的强还原型煤形成的基本模式。

| Abstract: | Obvious suppression in vitrinite reflectance is discovered with strong-reductibility coals(facies I and II )in the Taiyuan Formation(C3 ) as compared with iso-thermally related weak-reductibility coals ( facies III ) in the Shanxi Formation (P11 ) . Parameters of organic petrology, organic geochemistry and fluorescence photometry are used in discussion of suppression in vitrinite reflectance and its possible origin. Finally, an origin model is proposed for perhydrous vitrinite and strong-reductibility coals |
