东营凹陷博兴洼陷西部沙三段巨厚砂岩体的物源和成因类型众说纷纭 ,见解各异。该文认为 ,高青、正理庄和金家砂岩体的物源区主要是南部的鲁西隆起 ,樊家砂岩体的主要物源区是青城凸起。在三种成因类型中 ,以辫状河三角洲最为发育 ,主要分布于高青、正理庄、金家和樊家等地 ;扇三角洲发育在花沟 ;湖相分布则较为广泛。各砂岩体由于成因类型不同 ,表现出的沉积特征也不相同。
The source and type of the giant sandstone bodies in the third member of the western Shahejie Formation of Boxing Sag in Dongying Depression are diverse and have different opinions. The article thinks that the source areas of Gaoqing, Zhengliezhuang and Jinjia sandstone bodies are mainly Luxi uplift in the south, and the main source area of Fanjia sandstone bodies is Qingcheng uplift. Of the three genetic types, the most developed are braided river delta, which are mainly distributed in Gaoqing, Zhenglizhuang, Jinjia and Fanjia and other places; Fan delta is developed in Huaguang; lacustrine phase is more widely distributed. Each sandstone body shows different sedimentary characteristics due to different genetic types.
