摘要
为讨论郯庐断裂带江苏段断层气体氡的地球化学特征,在重岗、晓店、桥北和何庄4个地点跨断层测量了断层气氡浓度。测量结果表明:郯庐断裂带江苏段上断层气氡浓度异常衬度为2.05~5.73,且其浓度异常主要集中分布在断裂带内及附近,这与活动断裂带地震活动性有很好的一致性。
This article discusses the geochemical features of the fault gas radon （Rn） in the Jiang su section of the Tanlu fault zone. The Rn concentration across the fault was measured at four lo- cations： Chonggang, Xiaodian, Qiaobei, and Hezhuang. Measurement results showed that the Rn concentration anomaly contrast in the Jiangsu section of the Tanlu fault zone was 2.05-5.73. The Rn concentration was mainly distributed in and near the fault zone and showed a good corre- lation with seismic activity.
