用高密度电阻率法剖面研究阿尔公-特山断裂的活动性

Study on the Activity of Algong-Teshan Fault with High Density Resistivity Profile

  • 摘要: 阿尔公-特山断裂位于地震活动相对较弱、研究相对较少的东北地震区。该断裂南段为呼伦湖的东边界,并发育断层陡坎,卫片上线性比较清楚,但是北段进入草原地貌后断裂特征几乎不可见。针对这种地表无明显特征并覆盖层较厚的断裂采用高密度电阻率法进行测量,在推测该断裂通过的地区布设测线,获得3条高质量的剖面图,并对剖面图进行地质解释。研究结果表明,阿尔公-特山断裂呈NE向展布,倾向NW,正断层运动性质,为全新世活动断裂。

     

    Abstract: Algong-Teshan fault is located in the Northeast seismic area with relatively weak seismicity and relatively less research. The southern segment of the fault is the eastern boundary of Hulun Lake, and the fault scarps are developed. The linearity of the satellite image is clear, but after the northern part enters the grassland landform, the fault characteristics are almost invisible. In view of this kind of fault with no obvious features on the surface and thick overburden, the geophysical prospecting method of high-density resistivity method is adopted to measure. The survey lines are arranged in the area where the fault is speculated to pass, three high-quality sections are obtained, and the geological interpretation of the sections is carried out. The results show that the Algong-Teshan fault is NE trending and NW tending, and it is a Holocene Active fault.
