| 摘 要： | 土壤氡浓度分布具有双分形特征,其分维值分别为D1=0.079 4和D2=1.4654,分形临界值为2 167.7 Bq/m~3.低于临界值的分形其分维值D1很小,代表了区域背景分布,其背景值为1 088.16 Bq/m~3.高于临界值的分形其分维值D2显著增大,反映该区发生了较强的成矿作用的叠加.分形临界值可以作为异常下限值.金狮岭地区土壤氡浓度异常区分布范围较大,表明具有较好的成矿远景.

| Abstract: | The distribution of radon concentration in soil contains the characteristics of double fractal,the fractal dimension is D1=0.079 4 and D2=1.465 4 respectively,and the fractal threshold is 2 167.7 Bq/m3.The fractal dimension value of D1 is very small, which represents the region background distribution,and its background value is 1 088.16 Bq/m3.The fractal dimension value of D2 is higher than the critical value,and the strong mineralization superposition occurs in the reaction zone.The fractal critical value can be used as the lower limit value.The distribution of radon concentration anomaly area in the area of the Golden Lion Ridge region is large,which indicates a better metallogenic prospect. |
