Abstract: Based on thermoluminescent age data accumulated for several years and the results of experiments at different P, T condition simulating faulting process, this paper states that the frictional heating caused by faulting may lead to the "annealing" of original ther-moluminescence of some minerals on the fault plane or even within the fault zone. The applicability of TL technique to dating episodes of faulting has been discussed as well.

Key words: TL dating, Ages of faulting, Frictional heating, TL annealing

摘要： 本文根据多年来研究断层活动所积累的热释光年龄资料和断层运动过程中各种温、压条件变化的模拟实验结果,阐述了断层运动所产生的摩擦升温有可能使断层面上乃至断层带内某些矿物原有的热释光“退火”,初步探讨了用热释光测年技术测定断层活动年代的可能性。
