The sedimentary systems were alluvial fan - braided fluvial river - lacustrine depositional systems during the paleocene - eocene, and braided fluvial river - lacustrine depositional systems during the oligocene - miocene
古新世始新世發育沖積扇辮狀河湖泊沉積體系，漸新世中新世發育辮狀河湖泊沉積體系。 -
The sedimentary facies of the jurassic penglaizhen formation in the studied area can be described as follows : from the edge of the basin, the source of deposition, to the center of the sedimentation are alluvial fan facies fluvial facies fan delta facies delta facies lake facies and lake floor fan facies in turn
研究區侏羅世蓬萊鎮期沉積盆地的沉積相類型分佈，從盆緣近物源區至盆地沉降-沉積中心區依次為沖積扇、河流相、扇三角洲相、河控三角洲相、湖泊相和湖底扇相等沉積體系。 -
The types of sedimentary facies were mainly fan - shaped delta, delta, binshore subaqueous fans, slump turbid fan, lake facies, fluvial facies

受海平面升降變化控制，區內沉積體系和沉積相的分佈具有明顯的分帶性，北部靠近源區以沖積扇或河流及三角洲沉積為主，向盆地方向以湖泊或海岸障壁-瀉湖、碳酸鹽緩坡沉積為主。中二疊世北部源區發生構造抬升，當時古氣候逐漸乾燥，成煤環境結束，沉積物以陸相河流、湖泊三角洲占優勢。 -
