摘　　要：提出活断层探测综合地球物理方法为遥感、地震勘探、高密度电法、放射性测量,对新乡-商丘断裂(东段)进行了探测,探测结果:研究区第四系覆盖层厚度约160 m,上断点埋深30 m左右,断距由上到下逐渐加大,所探测的断层最新活动时代为晚更新世(Q3p)。结合本次新乡-商丘断裂东段的探测成果,总结出了一套活断层探测技术方法体系。The comprehensive geophysical methods for active fault detection are remote sensing,seismic exploration,high-density electrical method and radiometric survey.The Xinxiang-Shangqiu fault(eastern section)has been detected.The detection results show that the thickness of the Quaternary overburden in the study area is about 160 m,the buried depth of the upper breakpoint is about 30 m,and the fault distance gradually increases from top to bottom.The latest active age of the detected fault is the late Pleistocene(Q 3 p).Based on the exploration results of the eastern section of the Xinxiang-Shangqiu fault,a set of active fault detection technology and method system is summarized.
