断层气氡灵敏“穴位”的试验研究

A TEST STUDY OF SENSITIVE " ACUPOINT" OF FAULT GAS RADON

用地球化学方法研究覆盖层较厚、构造交汇部位的土壤中氡的含量，结合该地域的地球物理资料及地震活动，评价了断层的现今活动性，并取得了初步结果，确定太行山前断裂的邯郸断裂与大名－磁县隐状断裂交汇部位为断层气映震灵敏“穴位”，磁县－南来村一段属于断层气映震灵敏点，即灵敏“穴位”。此段可作为进一步试验研究该地区地震活动的理想场所。

By using geochemical method to study the radon in soil on structural convergence position with relatively thick overlay and combining the geophysical data and seismicity in that region, the present activity of the fault has been evaluated and a preliminary result has been obtained. The convergence positionof Handan fault of the Taihang mountain rangefront fault and Daming-Cixian hidden fault is defined asa sensitived acupoint' to respose earthquakes by fault gas, the Cixian-Nanlai village section belongsto a sensitive point to response earthquakes by fault gas, that is a sensitiven acupoint'. This section canbe taken as an ideal place to make a further test study on seismicity in that region.
