前言电子自旋共振(ESR)法在最近已开始用于测定断层运动的年代,池谷发表了用 ESR法测断层泥中石英颗粒 E′心的结果。但对 ESR 信号的相消并不能保证,所测结果有一定的偏差,因为不完全复零,测得的年龄会偏老。本文通过两种方法来检查断层的 ESR 年龄是否可靠;一是对断层泥中的石英颗粒及断层运动时侵入的石英脉进行测定,二是对石英颗粒各种晶格缺陷的讯号进行比较,以估计“复零”的程度。
Introduction The electron spin resonance (ESR) method has been used recently to determine the movement of the fault. In the report, Ikeda published an ESR method to measure the E ’core of quartz particles in mud. However, the cancellation of the ESR signal can not be guaranteed. The measured result has a certain deviation. Because the measured value is not completely zero, the measured age is older than the expected value. In this paper, two methods are used to check whether the ESR of the fault is reliable. One is to measure the quartz particles in the fault mud and the quartz pulse intruding during fault movement. The other is to compare the signals of various lattice defects in quartz particles. Estimate “zero reset ” level.
