【摘要】 通过对华北盆地滨海和三角洲环境下形成的石炭二叠系（晚石炭太原组C₂和早二叠世山西纽P₁¹）腐殖煤的镜质组单组分样品的煤岩学、有机地球化学、煤化学、生物标志化合物和分子化学结构等参数的详细分析确认,研究区腐殖煤的镜质组存在两种基本类型,即富氢镜质体（Ⅰ型）和贫氢镜质体（Ⅱ型）。更多还原

【Abstract】 Through the study and analysis on the parameters of coal-petrology, organic geochemistry, coal chemistry, bio-labell compounds and molecular chemical structure of vitrinite samples, it is confirmed that the two basic types-hydrogen-rich vitrinite (type I ) and hydrogen-poor vitrinite (type Ⅱ ) exist in the vitrinites selected from permo-qdrboniferous (Taiyuan Formation, C2 and Shanxi Formation, P1) humic coal formed in. coastal waters environment (tidal flat and delta) in North China basin.更多还原
