黄县盆地早第三纪黄县组的沉积环境 ,存在两种不同的认识 ,一种认为属内陆淡水湖泊沉积 ,另一种认为是滨海泻湖沉积。本文采用盆地分析的基本原理和方法 ,对黄县盆地的沉积体系与相构成进行了研究。结果表明 ,黄县盆地早第三纪为地处近海的海侵湖环境 ,盆地沉积体系的发育和配置受海水侵入及盆缘断裂的共同影响 ,呈现规律性展布 ,聚煤作用发生于海侵后的湖泊作用加强阶段。聚煤作用的有利部位为扇三角洲与水下扇前缘的淤浅湖泊区
There are two different kinds of sedimentary environment in Huangxian Formation of the Early Tertiary in Huangxian Basin. One is thought to belong to inland freshwater lacustrine deposits and the other is to be considered as a sedimentary lagoon in the lagoon. In this paper, the basic principles and methods of basin analysis are used to study the sedimentary system and facies composition of Huangxian basin. The results show that the Early Tertiary in the Huangxian Basin was an intrusion sea environment near the sea. The development and configuration of the sedimentary system in the basin were affected by the intrusion of seawater and the basin edge faults. The coalescence occurred regularly in the sea transgression After the lake to strengthen the stage. The favorable site for coal accumulation is the shallow and shallow lakes of the fan delta and the front of the underwater fan
