玛曲断裂带土壤气汞、氡地球化学特征

The Geochemical Features of Mercury and Radon on Maqu Active Fault

根据汞、氡土壤气在断层上的形成机制,分析了玛曲断裂带土壤气中汞、氡地球化学异常特征,并依据异常判断了断层的位置、产状、性质。与断层的实际剖面所反映的断层规模与性质基本耦合。为评价活断层提供了有益的参考。

According to the forming mechanism of soil gases above faults,the abnormal geochemical features of mercury and radon on Maqu active fault are analyzed.The position,occurrence and mechanical property of Maqu active fault are determined by the abnormal geochemical features,and which are consistant with the scale and characters of the fault from the fault section.The conclusions provided a useful reference for active faults evalution.
