Abstract

Since anomalous fading (AF) is a problem for ThermoLuminescence (TL) dating (Sfampa et al. in Nucl Instrum Methods Phys Res Sect B Beam Interact Mater Atoms 320:57–63, 2014), the current work examines both AF and Isothermal Decay (ID) of TL signals of amazonite from Tangir Valley, Gilgit-Pakistan. It is supposed that any previous research has not been done on either the AF of this amazonite or the ID characteristics. Apart from the general-order kinetic theory, the obtained signals do not highly dependent on temperature. This can be taken as a kind of direct experimental proof that the amazonite may exhibit tunnelling processes (Sfampa et al. in Nucl Instrum Methods Phys Res Sect B Beam Interact Mater Atoms 320:57–63, 2014). The ID curves were investigated and discussed in the context of the tunnelling kinetic model of TL.
