| 摘 要： | 我国华南的江西乐平、浙江长广和贵州水城地区以出产特种煤一树皮煤而闻名．其煤岩组分中含有特殊组分树皮体，该煤具有较高的挥发份、氢含量及焦油产率等化学特征，同时也具有良好的生烃潜力。相关的煤相研究可为该煤种树皮体的富集现象提供相应的成因信息。通过对各矿区煤层的煤岩学和矿物学的研究，发现主采煤层的显微组分均较富集树皮体，显微组分的形态特征及其组合关系反映主采煤层的形成环境为潮坪泥炭沼泽沉积环境。依据凝胶化指数（GI）、植物组织保存指数（TPI）、地下水流动指数（GWI）和植被指数（VI）力这4个煤相参数对其成因进行研究，根据各参数之间的关系图，确定了各矿区煤层成因信息的异同点．并对其所具有的不同地球化学特征进行了分析和解释。

| Abstract: | The southern China bark coal producing areas have Leping in Jiangxi, Changxing-Guangde in Zhejiang and Anhui, Shuicbeng in Guizhou. Bark coal contains barkinite, a special kind of maceral, makes the coal contains higher volatile matter, hydrogen content and tar yield, as well as good hydrocarbon originating potential. Related coal facies study can provide corresponding genetic information of the barkinite enrichment in the coal. Through coal petrological, mineralogical studies of coal seams in each mine area, have found that barkinite are concentrated in main mineable coal seams, macera｜ morphological features and composite relations reflected forming environment of main mineable coal seams is tidal peat bog environment. According to 4 coal facies parameters of gelification index （GI）, plant tissue preservation index （TPI）, groundwater index （GWI） and vegetation index （GI） carried out genetic studies. Based on relationship diagram between parameters, found out similarities and differences in coal seam genetic information of each mine area, then analyzed and interpreted their different geochemical features. |
