| 中文摘要: |
| 隐伏构造格架空间形态主要由深部孕震环境分析及浅部浅层定位等多组合方法进行精细探测，研究目标区断裂构造活动时代。深部空间特征主要由大地电磁测深与深反射地震推断解释，浅层空间特征由浅层地震勘探与地质钻孔联合勘探，地层年代主要通过地层岩性、沉积颜色、光释光测年等，综合分析研究确定地层错段的最新时代。本文以郑州市某隐伏构造活动性探测与评价为研究基础，通过组合方法探明地下埋藏的隐伏活断层，揭示其精确空间位置、活动时间，判定该构造为第四系早中期的隐伏断裂，为城市评估活断层危险性和危害性提供了依据，并对其他城市隐伏区活动断层探测有一定的借鉴意义。 |
| 英文摘要: |
| The spatial of the buried tectonic framework is mainly detected by the combination of multiple methods， such as deep seismogenic environment analysis and shallow shallow layer location， to study the fault tectonic activity time in the target area. The deep space features are mainly explained by magnetotelluric sounding and deep reflection seismic inference， and the shallow space features are jointly explored by shallow magnetotelluric and geological drilling. The stratigraphic age is determined by comprehensive analysis and research mainly through the formation lithology， sedimentary color and photoluminescence dating. Based on the exploration and evaluation of the activity in Zhengzhou， this paper explores the buried buried active fault by combining methods， reveals its precise spatial location and activity time， and determines that the structure is a buried fault in the early and middle Quaternary system， which provides a basis for the city to assess the risk and harm of active fault. It can be used as a reference for the detection of active faults in other urban hidden areas. |
