【摘要】 利用传统方法和粒度分析,在研究区的沉积特征研究上实现了定量化,同时在前人的基础上对研究区进行了系统的深入的研究,通过研究得知黄河北煤田晚古生代山西组的地层沉积环境以海陆交互的三角洲沉积环境为主,海水整体的下退,而且未出现大的海侵,三角洲平原相最为发育,其中以分流河道相为主,为河控浅水三角洲沉积体系。更多还原

【Abstract】 By means of the traditional analysis and make use of analy the size of grains,the study area’s depositional character is quantified,simultaneity,in the base of anterior study,we lucubrated for the prosecution of this study.After this work concerned,the author at last elicited the truth,Huanghebei coalfield’s Carboniferous-Permian’s Shanxi formation depositional environment mainly develops Fluvial-dominated shallow water deltaic depositional system,the sea water falling on the whole.The fluvial-dominated shallow water deltaic depositional system have a outstanding characteristics : distributary channels develop well in deltaic plain.更多还原
