位于黄骅盆地南部的孔西潜山的前第三系内幕构造十分复杂。通过理论模型分析以及对孔西潜山的地震剖面和探井资料的综合分析后认为 ,孔西潜山的主体部分是由 3～ 4条向东倾斜的铲式或坡坪式逆冲断层组成的“薄皮”叠瓦扇构造 ;卷入变形的地层主要是奥陶系、石炭二叠系 ;逆冲断层在寒武系或更深的地层中收敛合并成为局部的拆离逆冲断层。但是 ,沿着构造带走向逆冲构造样式有明显变化 ,孔西潜山南部表现为逆冲三角构造带。从卷入逆冲构造的地层的地质时代推测 ,逆冲构造主要是在早中三叠世盆地发育之后、侏罗白垩纪盆地形成之前形成的 ,并在早中侏罗世盆地发育过程中又有进一步活动。局部由于受到中、新生代时期的伸展构造和走滑构造的叠加 ,构造样式变得更加复杂。
The former Tertiary formation in the Kongxi buried hill in the southern part of the Huanghua basin is complex. Through the theoretical model analysis and the comprehensive analysis of the seismic profiles and exploration data in the Kongxi buried hill, it is concluded that the main part of the Kongxi buried hill is a “thin skin” stack composed of 3 to 4 eastward inclined shovel-type or ramp-type thrusts The fan strata involved in deformation are mainly Ordovician and Carboniferous Permian. Thrust faults converge and converge into partial detachment thrust faults in the Cambrian or deeper strata. However, the tectonic strike-trending tectonic belt changed obviously along the tectonic belt, and the southern part of the Kongsi buried hill showed a thrust triangular structure zone. It is speculated from the geologic age of the strata involved in the thrust structure that the thrust structure was formed mainly after the Early Triassic basin developed and before the Cretaceous Basin of the Jurassic. During the development of the Early Jurassic Basin Have further activities. Due to the superimposition of extensional structures and strike-slip structures during the Meso-Cenozoic period, structural styles have become more complicated.
