摘　　要：石炭二叠纪含煤地层主要赋存于鲁西隆起区的一些断块坳陷区和济阳坳陷区。研究表明 ,济阳坳陷区的石炭二叠系从沉积特征、古生物组合等方面与鲁西区有重要区别 ,并发现了在鲁西不存在的古生物属种 ,其沉积环境也与鲁西存在差异。进行了鲁西和济阳地区层序地层对比 ,鲁西地区层序的内部构成主要以潮坪沉积体系为主 ,而济阳地区层序内部构成主要以障壁 -泻湖沉积体系为特征。The Permo Carboniferous coal bearing measures mainly occur in the fault depression of Luxi uplifted area and in Jiyang sag in Shandong.The study result shows that the Permo Carboniferous in Jiyang sag is of great difference from that in Luxi area in the depositional characteristics and the combination of ancient lives.The depositional environment is also different in both areas.New species and genera of ancient life other than that in Luxi has been found in Jiyang sag.Stratigraphic sequence correlation of the Permo Carboniferous in both areas has been made.The sequence classified in Luxi is mainly composed of tidal flat sedimentary system while mainly barrier lagoon system in Jiyang sag.
