【摘要】 利用MT和EH4大地电磁测深的方法,在对天津市宁河县的断裂构造格局进行了新一轮的探测后,结合前人航磁、重力、电法和地震等资料,重新确定了该地区的断裂构造格架。为了进一步掌握断层的确切位置,笔者利用FD-3017镭A测氡仪对断裂带及其附近位置的土壤氡含量进行了测量,发现在厚大的第四系覆盖地区,土壤氡含量对断裂构造的反应敏感,断裂带正上方氡含量最高。该方法具有实用推广价值。更多还原

【Abstract】 Through the MT and electromagnetic method,the fault structure in Ninghe County, Tianjin was surveyed again.Combining with the former information of aeromagnetic,gravity,electric and earthquake survey,the fault structure in this area was reestablished.And in order to know the real position of the faults,the author used the radonscope FD3017 La A to survey the fault zones and the nearer places,and found that the higher Radon content is just on the fault zones in the place covered by the thick Quaternary system.So,this method should be popularized quickly.更多还原
