氡断层气测量在佛山西淋岗活断层探测中的应用研究

An Experimental Study on Active Fault Radon Gases Measurement in Foshan Xilingang Fault

在佛山西淋岗活断层附近,垂直断层走向等距测量了断层附近载体中氡气相对含量值,得到了氡含量曲线图,分析了断层气上氡异常形态分布特征,探讨了断层气载体对氡异常形成的影响。

Based on the mechanism of fault gases such as radon and mercury gases formed in faults, taking Foshan Xitingang active fault as an example, through surveying the content values of radon in near-fauh carriers in the direction perpendicular to the strike of fault and at an equal distance on both sides of the fault, we got the radon gases content curve. We analyzed the characteristics of anomaly shape of the radon gases content curve and discussed the influences of fault gases carrier on the radon abnormal form. We propose some suggestions on the relevant work of geochemical fault gas measurement. These provide a useful reference for urban active faults surveying and evaluation.
