The Jiyang depression is located in Southeastern of the Bohai Bay Basin and borders on Tancheng—Lujiang fault(Tanlu fault) zone which is a huge strikeslip fault. In the process of rifting, it has been controlled by the regional extension and strikeslip of Tanlu fault since Late Mesozoic. Normal faults and strikeslip faults developed, but their relationship are not well understood. So, the paper focuses on the geometry of three dimension to analyze their interplay.Methods:Based on the interpretation of 3D seismic and the distribution of faults in plane, strikeslip faults are recognized and separated into five zones. The interplay are analyzed between normal faults and strikeslip faults in order to figure out their relationships. And then, dynamic background and major factors of rifting are considered in different tectonic phases. The mechanisms of the interplay are discussed and rationalized.Results:The relationships between normal faults and strikeslip faults are divided into the accommodated, the associated, the alternative. The accommodated relationship could be further divided into the oblique faulting and the transformation. The associated relationship could be divided into that the secondary normal faults were associated in the footwall/hangningwall and overlying strata by strikeslip faults. The alternative relationship could be divided into “prestrike slip and postextension” and “preextension and poststrike slip”.Conclusions:In Late Mesozoic, the strikeslip of Tanlu fault associated the faults in Jiyang depression. And the relationship was the associated between the normal fault and strikeslip fault. In Cenozoic, Jiyang depression was controlled by the regional extension. And the strikeslip faults was developed by the differential extension of normal faults, so the relationship was the accommodated between that two kinds of faults. In the two phases of structural evolution, some faults experienced the normal faulting and strikeslip faulting. So, the relationship was the alternative between different stages.
