| 摘 要： | <正> 前言α径迹法是一种确定土层α射线强度的新技术,通过埋设在不同空间的测片上留下的痕迹密度差异,分析断裂构造的展布位置及活动程度。早在六十年代中叶地质工作者就开始利用裂变径迹来测定地质年代,地下氡气含量,研究岩石放射性在土壤里的分布规律。继后,径迹探测技术又被广泛地应用于核科学,地球物理学,地质找矿及找水等领域。八十年代,

A SURVEY ON THE ACTIVITY OF TAN-LU FAULT ZONE(JIANGSU SEGMENT)BY α-TRACK METHOD |
| |
| Abstract: | This paper studies the variation of α-track density in Tan-Lu fault zone.Several understandings are put forward by comparing with those in different type faults. 1.The α-track density in Tan-Lu fault is 1-3 times higher than those in inactive faults in Jiangsu and nearby areas; 2.Data from 11 measured profiles show that the intensities of activity are generally same within the Jiangsu segment of Tan-Lu fault zone; 3.The α-track method can reliably measure the attitude of a hidden fault; 4.Data of re-measuring show that there is correlation between earthquake and the variation of α-track density. |
