【摘要】 通过对野外露头、钻孔、砂分散体系以及地震相等资料的分析,同时将前人对构造背景与沉积体系的研究相结合,对孟津井田石炭-二叠系含煤地层各层沉积环境进行了分析。结果表明,孟津井田石炭-二叠纪形成于滨海沉积体系与三角洲沉积体系;聚煤盆地在时间上和空间上存在成煤环境和成煤模式的多样性,浅水三角洲成煤模式是区内存在的主要成煤模式。更多还原

【Abstract】 Based on the analysis of outcrop,borehole,sand disperse system and seismic facies,combined with the research findings in depositional system and tectonic background,the sedimentary environments of the Carboniferous Permian coal bearing stratum in Mengjin coalfield were researched. The results show that the Carboniferous Permian is formed in littoral sedimentary system and delta sedimentary system,the coal accumulating basin has variety of coal forming environment and coal forming pattern in time and space,and shallow water delta coal forming pattern is the main coal forming pattern in Mengjin coalfield.更多还原
