夏垫隐伏断裂土壤气氡分布特征的初步研究

PRELIMINARY STUDY ON SOIL-RADON DISTRIBUTION ALONG THE XIADIAN BURIED FAULT

通过横切夏垫隐伏断裂的土壤气氡剖面测量，作者发现，土壤气氡的正异常区位于该隐伏断裂上盘的地表投影区内。断裂附近的土壤气氡等值线分布表明，沿夏垫隐伏断裂，气氡等值线有一个明显的梯度带。

Based on soil-radon profile survey across the Xiadian buried fault,the authors discoveredthat the positive anomaly area of radon in soil occurs on surface projection of the hanging wallof the buried fault.The isogram of radon near the fault shows that the distribution of radonvalues along the fault has an obvious gradient zone.
