摘要
广西晚二叠世成煤模式划分为“两类三型”，即泥炭沼泽成煤模式和泥炭坪成煤模式两类，沼泽型、潮坪型和泥炭坪型等三型。文章阐述了这些成煤模式在吴家坪期和长兴期形成的特征，分布状况，以及代表煤层，指出潮坪型是广西晚二叠世时期最主要的成煤模式。
The coal-forming models in late permian eporch in Guangxi are divided into 'two classes and three types', the two classes are peat bog coal-forming model and peat flat coal-forming model, the three types are bog type, tidal flat type and peat flat type coal-forming models. This paper deals wiht the forming characteristics of these coal- forming models, their spacial distribution conditions and typical coal layers in Wujiapin age and Changxing age, it points out that the tidal flat type was the most typical coal-forming model in late permian epoch in Guangxi.
