摘要: 活断层的勘探是城市发展中的一项重要任务。根据氡、汞断层气在断层上形成的机制,分析了断层气上氡、汞异常形态特征。根据长春市两条已知断层实例,分析了断层上土壤氡气、汞气异常的特征,可用该特征来确定断层的位置、产状以及推测断层的规模,探讨了盖层的性质对异常形成的影响。它们可为活断层勘探、评价提供有益的参考。

Abstract: The detection of urban active faults is one of the main goals in city developments. Accor ding to the mechanism of fault gases such as radon and mercury gases formed above faults, the authors analyzed the radon and mercury gases anomaly characteristics above active faults. The analyses had been made on these characteristics above these faults of the soil radon and mercury gases anomaly based on two known faults in Changchun. The fault locations and their occurrences can be determined and the fault scales can be predicted by these characteristics. The authors discussed the influences of super cover layer properties on abnormal form. These conclusions provided a useful reference for urban active faults surveying and evaluation.

Key words: active fault, fault gas, soil radon measurement, soil mercury gases measurement
