摘要
山东是华北地区较早接受晚古生代地层沉积的地区,分布于沂沭断裂带以西地区,自下而上划分为月门沟群和石盒子群,富含动植物化石和煤炭、铝土矿等矿产资源。该套地层不整合于奥陶系之上,顶部遭受风化剥蚀,被三叠系不整合覆盖,在不同地区地层厚度、岩性及含矿性特征差别较大。沉积环境由海相—海陆交互相向陆相演化,主要分为海洋环境、海陆过渡环境、湖泊环境、沼泽环境和河流环境。
Late Paleozoic strata originally generated and sedimented in Shandong province in north China, and Carboniferous and Permian strata developed completely.Carboniferous and Permian strata,which pre-cisely formed in late Carboniferous and late Permian distributed in Mesozoic and Cenozoic basins in west part of Yishu fracture zone,and divided into Yuemengou group and Shihezi group from bottom to top,en-riched in animal and plant fossils,coal,bauxite and other mineral resources.The stratigraphic unconform-ity occurred between this strata and upper part of Ordovician.Subsequently,this strata suffered from weathering and erosion at the top,and was overlapped by Triassic unconformity.The formation thickness, lithology and ore bearing characteristics are different in different areas.The sedimentary environment was evolved from marine and marine land transition to land,and mainly divided into marine environment, transitional environment,lake,swamp and river environment.
