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. © 2023, Akadémiai Kiadó, Budapest, Hungary.Englisharticledegradation kineticskineticsPakistanthermoluminescenceArticle10.1007/s10967-023-08911-7
