摘要
在对延庆松山泉水汞观测资料进行清理和总结的基础上 ,对该泉水汞的映震能力进行了评价和研究 .研究结果表明 ,该泉水汞异常与地震的对应率较高 .1 997年以来 ,其异常对于测点附近发生的有感地震及中小地震和距测点较远范围内发生的 5级以上地震有很高的对应率 .根据地质构造的活动特征对该泉水汞映震灵敏的原因进行了初步探讨 .
On the basis of analysis of observation data for mercury content in Songshan spring of Yanqing county,Beijing city, reflecting earthquake ability of mercury anomaly of the spring is studied and evaluated.The results show that there is a better correspondence between mercury anomalies of the spring and earthquakes. Especially,there is obvious correspondence between the anomalies and mid small earthquakes near the spring and M S≥5 earthquakes far away the spring since 1997.The cause of sensitivity reflecting earthquake for the anomalies of the spring is discussed from activity of geological structures around the spring.
