摘　　要：江西省东北乐平地区的上二叠统龙潭组煤层因富含树皮体而称之树皮煤,为了明确龙潭组煤成油的机理和勘探前景,文章用有机岩石学方法获得树皮煤显微组分以树皮体为主,同时富含基质镜质体、小孢子体等富氢组分;用生烃模拟实验方法得到树皮煤的产烃率很高,是迄今已知的最好的煤成油烃源岩;通过单组分生烃模拟实验证实树皮体最有利于生成液态烃;树皮煤形成于热带—亚热带潮间带(部分潮上带)泥炭坪,成煤物质来自于红树林—半红树林植物群。The coal bed of Longtan Formation, Upper Permian, in Leping region in the northeast part of Jiangxi Province is called bark coal because of being rich in peribunites. In order to definite the mechanism and exploration potential of bark coal-formed oil, by means of organic petrological method, it was found that the macerals of bark coal are mainly composed of periblinites and abundant in the hydrogen-rich components as degradinites, microsporinites, and so on. The hydrocarbon-generating simulation experiments proved that the hydrocarbon productivity of bark coal was very high, it being the best source rock of coal-formed oil known up to now. Through single component hydrocarbon-generating simulation experiments, it was indicated that the periblinites were beneficial to generating liquid hydrocarbons. The bark coal was formed in the intertidal zone (partial supratidal) peat flats of tropics-subtropics, and the coal-forming materials came from the florae of mangroves and half-mangroves.
