Disorder-enhanced luminescence kinetics in volcanic feldspars

A granitic feldspar is well-ordered and has a stable thermoluminescence signal enabling its dating with high reliability. In contrast, a volcanic feldspar (sanidine) exhibits a slight cristallographic disorder and an anomalously fast fading of the thermoluminescence signal (Visocekas et al. 2014). It is shown here how disorder changes the decay of the signal and enhances the kinetics, while the increase in the microscopic complexity plays no role.
