The author collected, organized, and analyzed data from 2,525 representative boreholes in the Handan region, conducted lithological stratification and established a database. Via the software platforms Petrel and ArcGIS, a 3D stratigraphic sequence-structural framework model was developed based on the typical borehole database and stratigraphic sequence-structural framework. The model provides valuable insights into the structural evolution in the Handan region, presenting structural maps, thickness maps, and Quaternary structural profile maps since the Late Quaternary. Through a detailed analysis of the deformation within the Qp 2 , Qp 3 , and Qh stratum groups, this study unveils the distribution patterns and activity characteristics of concealed faults, including the Taihang Mountain piedmont fault (F1), the Handan concealed fault (F2), and the Lianfanglu fault (F3).
