研究了黄县含煤盆地沉积充填序列、沉积组合及其空间配置,识别出4种沉积体系类型;划分出2个Ⅲ级层序;分析了盆缘断裂的活动特点及煤的聚积规律.研究表明,盆缘断裂的活动控制了盆地的形成、发展和演化.盆地充填沉积序列可划分出2个构造沉积旋回.其沉积体系构成主要有冲积扇扇三角洲沉积体系、辫状河三角洲沉积体系、滨浅湖湖沼泽沉积体系和深湖浊积沉积体系.其中以低水位水进体系域中的扇三角洲、辫状河、滨浅湖湖沼沉积体系与聚煤作用具有密切关系.主要煤层形成于低水位水进体系域,聚煤作用中心随盆地水域体制的变化而发生迁移.
The sequence of sedimentary filling, sedimentary assemblage and its spatial distribution in Huangxian coal-bearing basin are studied, and four types of sedimentary system are identified, and two Ⅲ-order sequences are distinguished, and the characteristics of activity and coal accumulation of basin margin are analyzed. The results show that the activity of basin margin controls the formation, development and evolution of the basin.The basin-filling sedimentary sequence can be divided into two tectono-sedimentary cycles.The sedimentary system consists of alluvial fan-fan delta depositional system, braided river delta deposition System, shallow lake-lake marsh sedimentary system and deep lake-turbidite sedimentary system, in which the low water level-water system system fan-delta, braided river, shallow lake-lacustrine sedimentary system and coal accumulation are close The main coal seams are formed in the low water level water into the system tract, and the coal accumulation center migrates with the change of basin water regime.
