| 摘 要： | 根据已有研究成果及大量钻孔资料,运用沉积学、煤田地质学的基本理论和方法,分析了徐沛煤田晚古生代的成煤环境,并总结了其聚煤规律及控制因素。结果表明,石炭—二叠纪聚煤作用主要发生在海岸带的堡岛体系和过渡相中,由海岸带向两侧,聚煤条件逐渐变差;堡岛体系泥炭坪形成的煤层厚度小,结构单一;三角洲体系分流间湾泥炭坪和泛滥平原泥炭沼泽形成的煤层厚度大;煤层在垂向上由薄至厚,结构由简单至复杂,稳定性逐渐变差;平面上,自北而南含煤层数逐渐增多,含煤层位逐渐抬高,条带状富煤带有向南迁移趋势。

| Abstract: | By the means of the principle and methods of sedimentology and coal geology,based on the detailed coring data and the coal-forming environment analysis,the paper has summarized the coal-accumulation pattern and the controlling factors of the Xupei coalfield during Late Paleozoic Era.The study has demonstrated that the Permo-Carboniferous coal accumulation has been happened mostly in the offshore barrier island system and transitional facies,and the coal-accumulation conditions gotten worse increasingly from... |
