    盆地內下白堊統朱巷組沉積特徵表現為：沿郯廬斷裂帶呈北北東向廣泛發育了沖積扇體系，從近斷裂帶西側出現的半深湖-深湖相，向西依次為濱淺湖相到泛濫平原相的規律性分佈，沉積厚度由東向西尖滅、超覆，構成了明顯的東斷西超的盆地構造格局，表明下白堊統的沉積中心依然位於盆地東部。
  2. Yanchang 4 + 5 sector to yanchang 3 sector lithofacies palaeogeography pattern was stable, because the constitution background was steady, and the source direction had no change, and supply was abundant. in those sectors the basin development was in lake retreat, and in the period of extinction gradually, and formatted construction delta deposit, but in yanchang 33 period the sedimentary speed were greater than construction speed, showing that overriding river mouth bars were abundant

    長4 + 5 ?長3期湖盆發展處于湖退、萎縮逐漸消亡時期，由於構造背景穩定，物源來源方向沒有變化，物源供給充分，所以巖相古地理格局基本一致，形成建設性三角洲沉積，但長3 ~ 3期沉積速率大於構造沉降速率，表現為疊置河口砂壩極其發育。
