摘要
本文在对各种宏观沉积特征进行研究的基础上,结合室内分析鉴定,提出第四含煤段是以河流作用为主受潮汐影响的浅水三角洲沉积,河流活动和频繁的泛滥洪水的垂向加积作用影响了泥炭沼泽的发育。活动的三角洲似乎不是成煤的有利场所。图7,表2。参5。
The theory that the 4-th coal-bearing member, is a shoalwater delta sediment in which river flowing takes a mainly role affected at the same time by tide is set up in this article based on numerous studying on varius visible sedimentary characteristics, and by taking into account the laboratory diagnosis and appraisal. The growth of peot swamp is affected by river activity and frequent overflowing flood's vertical accretion. It seems that anactive delta is not a good place for coal forming.7figs., 2tabs., 5refs.
