Based on geophysical data, including high-precision gravity, aeromagnetic and seismic data, this paper describes the pre-Cenozoic residual basin structure of Huanghua Depression, builds three-dimensional basin macro-frame, analyzes pre-Cenozoic residual spread and thickness features, and discusses the trichotomous property of basement in terms of potential field forward stripping and regularization filtering. The results revealed that Huanghua Depression has the basin area of vertical stratification, East and West sub-zone, North-South structural features. Pre-Cenozoic residual basin in general is NNE-NE direction to the distribution, but the sedimentary center and the residual strata thickness differ from those of Cenozoic and the residual thickness is smaller in Qikou Cenozoic area. The basement shows characteristics of trichotomy, that is, “T” type intersection of two hidden deep faults may be the stitching line among Yanliao, Luxi and Taihang basement. Pre-Cenozoic basin structure, residual thickness and trichotomous property of basement are all shown by the impact and control of deep faults.
