SER DATING OF THE F1 AND F7 FAULTS IN THE ZHANGHEWAN RESERVOIR DISTRICT, HEBEI
-
摘要: 本文叙述了电子自旋共振(简称ESR)法所测定的河北省张河湾水库F1、F7断层的年龄,将ESR年龄和以往测试的TL年龄进行对比,两种方法测试结果基本吻合,证明ESR测定第四纪断层的可能性,F1、F7断层的年龄值均大于定义的活动断层年龄值下限(1.1×104a)。因此,它们不属活动断层,这个结论也被其它地质观测手段所证实。Abstract: ESR method was nas used for dating the F1 and F7 faults in Zhanghewan resovoir distict, Hebeiprovince. The results are comparable with that obtained by TL dating before.This indicaes the feasiblity of the method for dating Quaternary faults. As the measured age values are greater than the characteristicage value of an active fault, 1.1×104, the faults F1 and F7 do not belong to active faults. This conclusion is supported by other geological observations as well.
