Abstract
We studied the formation of E(1)' precursors in quartz of diverse orig in using electron spin resonance. We found that after annealing at 600 degrees C the natural E(1)' signal level could be regenerated by heav y gamma radiation plus another heat treatment. The formation process e xhibited temperature dependence. We concluded that this dependence mig ht affect our ability to date quartz, but also that signal regeneratio n can now be applied to obtain minimum ages for Phanerozoic igneous an d vein quartz.
