| 摘 要： | 断层氡气释放强度、范围、成分等的变化可以用来分析评价活动断层的相对活动性.研究了天水地区主要活动断裂的基本特征,并对这些断裂进行了氡气测试与分析.结果表明:西秦岭北缘断裂带的活动性为强-极强;礼县-罗家堡断裂的活动性为强;礼县-积石峡断裂的活动性为强-中等;清水断裂活动性为中等.该结果与活断层的活动强度较吻合,说明氡气测试成果可以作为一种断裂活动性的评价方法.

| Abstract: | The change in intensity, scope and component of radon released from faults can be used to analyze and evaluate the relative activity of active fault. The basic feature of main active faults in Tianshui area is analyzed. And the radon content is surveyed, the result shows that the activity of west Qinling fault is strong to extremely strong,the activity of Lixian-luojiabu fault is strong,the activity of Lixian-jishixia fault is strong to middle,the activity of west Qingshui fault is middle. The survey result... |
