摘要
In this paper, the Early Paleogene (Ek-Es4x) structure framework of Dongying Sag was researched through geometrical and kinematic analysis of the fault systems. The results show that the period of Early Paleogene (Ek-Es4x) is the stress field transformation phase and the NE faults begin to develop while the former Mesozoic faults (NW) last active, which are made up of the basin-control fault system, dominating the original strata sediment. The Early Paleogene (Ek-Es4x) prototype basin in Dongying Sag presents as a faulted basin with the north faulted boundary and the south overlapped to the Luxi uplift. The whole basin inherits the original deposition, and is divided into three parts (Chennan zone, Boxing zone and Linfanjia zone).
