摘　　要：从煤层的煤系地层发育特征、沉积体系以及聚煤规律等方面研究了鄂尔多斯盆地东部上古生界成煤环境及其空间分布规律,恢复了盆地东部上古生界的沉积演化过程以及成煤历史。泥炭坪和泥炭沼泽是该盆地成煤的最主要2大环境,同时,该地区主要有3种成煤模式(障壁海岸聚煤模式、潮控三角洲成煤模式、河流(或三角洲平原)成煤模式),形成了一套广覆型沉积的含煤岩系。According to the development characteristics of coal measure strata,the sedimentary system and coal-accumulating patterns of Paleozoic in the east of Ordos Basin are analyzed,the upper Paleozoic coal measure environment of eastern Ordos Basin and restoration of the sedimentary basin are studied.The research shows that the mire marshes and the peat flat are the main coal-measure environment.At the same time,the three main coal-measure systems are the beach-barrier coal accumulating system,the tidal delta coal-bearing system and the fluvial or delta plain coal-bearing system,they form a coal-measure series with wide sedimentary coverage.
