Application of Balanced Cross Section on the Basin Analysis for Cenozoic of Huanghua Depression
Abstract:
In this paper, the seismic profiles of the central area of Huanghua depression were balanced and restored by 2DMove software. We calculated the extension parameters of the balanced corss-section in the different period, analyzed the tectonic deformation of Huanghua depression. According to the total extension parameters of balanced cross-section, the Cenozoic evolution of the Huanghua depression may be divided into two phase of tectonic evolution which are rifting stage and post-rift stage. The rifting stage included three episodic rifting: The third members of Shehejie with the rapidest subsidence,Ⅰepisodic rifting; The first and second members of Shahejie with the fault-depression,Ⅱepisodic rifting; The Dongying with terminal fault-depressed ,Ⅲepisodic rifting . The Huanghua depression shows a double-layer vertical structure with faulting structures in the lower and depressing structure in the upper sector.
