摘要:
郑州地处华北地块南缘与秦岭造山带北缘构造交汇带，地下隐伏断层发育，其深部地壳结构特征对区域地震危险性评估及城市规划具有重要意义。在郑州市东南部航空港区，采用5台28t可控震源车组合激发模式，完成了一条长度为25km的深地震反射剖面探测，系统揭示了研究区地壳精细结构、莫霍面形态及深浅断裂连通性特征。研究表明：该区地壳TWT6.5~7.0s处的强反射带为康拉德面（上下地壳分界面），上地壳厚度约20~21km，下地壳厚度约12~14km；TWT10.2~11.0s处的反射对应莫霍面，其深度约为32~35km。上地壳沉积层发育特征显著，共识别出新郑—太康断裂、大隗断裂、郭店断裂及张庄断裂4条主要隐伏断层，其中新郑—太康断裂与张庄断裂为区域构造边界大断裂，向下延伸深度约15km，大隗断裂与郭店断裂向下归并于新郑—太康断裂。莫霍面在研究区呈不连续分布，具叠瓦状逆断层特征，反映了挤压构造背景下华北克拉通的活化特征。本次探测填补了郑州及周边区域深部地震构造研究的空白，完善了区域地壳结构模型，为郑州城市地震危险性评估、国土空间规划及防震减灾工作提供了重要的深部地球物理数据支撑。
Abstract:
Zhengzhou is located at the tectonic junction of the southern margin of the North China Block and the northern margin of the Qinling Orogenic Belt, with well-developed buried faults underground. Its deep crustal struc‐ture characteristics are of great significance for regional seismic hazard assessment and urban planning. In this study, a 25-km-long deep seismic reflection profile was completed in the airport zone of southeastern Zhengzhou by using a combined excitation mode of five 28-ton vibroseis vehicles, which systematically revealed the fine crustal structure, Moho morphology and connectivity of deep and shallow faults in the study area. The results show that the strong reflection zone at TWT of 6.5-7.0 s in the study area corresponds to the Conrad discontinuity (the boundary between the upper and lower crust), with an upper crustal thickness of about 20-21 km and a lower crustal thick‐ness of about 12-14 km; the reflection at TWT of 10.2-11.0 s corresponds to the Moho discontinuity, with a depth of about 32-35 km. The development characteristics of the upper crust sedimentary layer are significant, and four main buried faults are identified, including the Xinzheng-Taikang fault, Dawei fault, Guodian fault and Zhang‐zhuang fault. Among them, the Xinzheng-Taikang fault and Zhangzhuang fault are major regional structural bound‐ary faults, extending downward to a depth of about 15 km, while the Dawei fault and Guodian fault converge down‐ward into the Xinzheng-Taikang fault. The Moho discontinuity is discontinuously distributed in the study area, with imbricate thrust fault characteristics, reflecting the activation of the North China Craton under the compressional tectonic background. This exploration fills the gap in deep seismic structure research in Zhengzhou and its sur‐rounding areas, improves the regional crustal structure model, and provides important deep geophysical data sup‐port for seismic hazard assessment, territorial spatial planning and earthquake prevention and disaster reduction in Zhengzhou.
