【摘要】 郯庐断裂带在江苏境内,大部分为松散层所覆盖。作者采用氡气、α径迹、汞、²¹⁰钋等四种方法对其进行测量,以确定其位置及产状,其结果与钻孔资料、人工地震和精密磁测成果一致。通过综合分析,认为郯庐带江苏段是一条活动性断裂,但断层气测量结果表明,其新活动水平不高。更多还原

【Abstract】 The greater part of the Jiangsu segment of the Tanlu fault zone was hidden by loosesediments.The location and strike-dip of the faults have been determined using fourgeochemistry methods:Rn gas,α-track,Hg and ²¹⁰Po,and the result consists with data ob-tained from men-made earthquake,drilling and geomagnetic precision measurement.Bymean of synthetical study,it is suggested that the Jiangsu segment of the Tanlu fault zone isan active fault,but the fault gas measurement shows that the fault activity is lower.更多还原
