| 摘 要： | 应用煤岩学与地球化学相结合的研究方法,探讨了黄陵矿区2#煤层的煤岩学特征及煤相类型。研究表明：2#煤层显微煤岩组分以镜质组为主,煤层从底部到顶部煤相由潮湿森林沼泽向开放沼泽过渡,包含五个次级演化层序,潮湿森林泥炭沼泽相是煤层煤相类型的主体,水动力条件较弱,成煤植物以木本植物为主,形成环境整体上为潮湿—覆水环境。

| Abstract: | Using combined coal petrology and geochemistry study method, probed into coal No.2 coal petrological characteristics and coal facies types. The study has shown that the maceral of coal No.2 is mainly vitrinite, principal part of coal facies is humid forest peat bog facies. From bottom to top, coal facies transits from forest swamp to open swamp with weak hydrodynamic conditions,contains five secondary evolution sequence. Parent material of coal is mainly woody plant; overall coal formation was in a humid—water covered environment. |
