There were three times of sea - level fluctuation corresponding to the paleo - climate evolution , which had formed the sediments of alternative sea and river facies
晚更新世以来的三次海平面升降变化造成了潍河下游地区海陆沉积环境交替，形成了巨厚的海陆交互相沉积层。
It is suggested that the distribution of the depositional systems and the depositional facies have the clear characteristic that in the north of the research area , the alluvial fan sediment , the fluvial system and the delta system are the main styles of the depositional system , towards to the direction of basin the lacustrine , the barrier , the carbonate ramp system become the main depositional systems
受海平面升降变化控制，区内沉积体系和沉积相的分布具有明显的分带性，北部靠近源区以冲积扇或河流及三角洲沉积为主，向盆地方向以湖泊或海岸障壁-泻湖、碳酸盐缓坡沉积为主。中二叠世北部源区发生构造抬升，当时古气候逐渐干燥，成煤环境结束，沉积物以陆相河流、湖泊三角洲占优势。
