摘要
对东胜煤田城梁井田、乃马岱井田原延安组底部地层进行了研究,并与区域中相同层位的地层进行了岩石地层学和气候地层学对比,认为在研究区或更大范围内都富存有早侏罗世晚期富县组。研究区富县组的发现,对原来侏罗纪煤系沉积基底为西北高、东南低的古地理格局及构造运动对盆地影响结果的观点产生了动摇,应该重新进行认识。
We studied the basal Yanan Formation in the Chengliang and Naimadai Minefield of the Dongsheng Coalfield.The lithostratigraphic and climatostratigraphic correlation of the basal Yanan Formation in the study area is proposed.We suggest that the late Early Jurassic Fuxian Formation occurs in the study area.The discovery of the Fuxian Formation in the study area has paleogeographic implications：the traditional view that the basement of Jurassic coal series is characterized by highs in the northwest and lows in the southeast needs to be reconsidered in light of the new discovery.
