Abstract:Based on the processing, interpretation, and comprehensive study of the two-dimensional seismic survey data in the key survey area of Xiongan New Area, we summarize the buried depth of the top and bottom of the main strata, the contact relationship, and the spatial distribution characteristics of fault structure within the depth of 3 000 m. According to the study, 16 sets of strata, including the Jixian system of the Middle Proterozoic, and 9 faults including Rongcheng, Rongnan and Xushui faults, developed within 3 000 m depth in the key investigation area of Xiongan New Area. The faults are hidden under the surface, all of which are high-angle normal faults, mainly in a north-eastern direction, controlling the uplifts and sags pattern and the spatial distribution of the Quaternary Lower Pleistocene, Neogene, Paleogene, Mesozoic, Qingbaikou and Jixian systems in the study area.
