摘要
贵州晚二叠世成煤环境复杂。根据岩性、岩相、煤质和有机硫δ^(34)S值可划分出河流、三角洲、坝湾和潮坪四种成煤环境,并指出三角洲成煤环境和坝湾成煤环境是贵州晚二叠世最有利的成煤环境。根据上述四种成煤环境的特征及分布,建立了贵州晚二叠世成煤模式。
Coal-forming environment of late Permina in Guizhou Province is very complex. It can be devided into four types: fluvial, delta, barrier-lagoon and tidal flat coal-forming environments according to Lithofacies and Palaeography, coal quality parameter and δ^(34)S of organic sulfur. It is considered that the delta and barrier-lagoon environments are the most advantageous coal-forming environments. The writers set up coal-gathering models of late permina in Guizhou by the characteristics and distribution of the above mentioned four types of coal-forming environments.
