Binzhou city is located in Jiyang depression in the southeast of Cenozoic subsidence area in North China. The underlying bedrock of Cenozoic is Paleozoic sedimentary strata and pre-Sinian metamorphic rock series.
Divided into several small fault blocks by several NE-trending faults, there is basically no Mesozoic strata, and the Cenozoic strata directly cover the Paleozoic strata. The fault block depression formed a Cenozoic depression basin and deposited a whole set of Cenozoic strata with great thickness. The stratum is interbedded with marine facies, lacustrine facies and alluvial debris, and contains a lot of organic matter, which is beneficial to oil generation.
Except the southern mountainous area of Zouping, most of the surface of the city is covered by Quaternary sediments, and the south of Xiaoqing River is in the middle and tail of alluvial plain at the northern foot of Luzhong Mountain, which is an overlapping zone between alluvial plain and alluvial plain, and the thickness of alluvial stratum is generally100 ~ 200 m.
