| 摘 要： | 在广从断裂带共布置5条氡气测量剖面,利用FD-3017RaA和CDI-2000两种氡探测仪快速测定其浓度,得到土氡含量曲线图和等值线图,并分析氡异常曲线的特征,得到如下结论:广从断裂上土壤氡具有明显的峰值异常特征,通过异常峰值位置能很好地圈定断裂或隐伏断裂的位置和断裂带的宽度;利用峰值异常的几何形态能很好地判断断层的倾...

| Abstract: | Five profiles along Guangzhou-Conghua fracture were employed in this research.CDI-2000 and FD-3017RaA were used to detect soil radon concentration rapidly.Then soil radon concentration curves and contour maps were ploted.The characteristics of soil radon anomaly curve were analyzed.The paper has several conclusions： Obvious abnormal peaks are observed,and location of fractures or concealed fractures and width of fractures could be well delineated according to location of abnormal peak;Inclination could be deduced by using the geometric shape of the peak anomaly;There is a clear correspondence between concentration ratio of radon and fault activity;The trend of the fracture could be well revealed on the basis of contour maps and measured line connected by peak values. |
