Abstract

Natural alkali-rich aluminosilicates minerals from Harmancik/Bursa/Turkey and Kepsut/Balikesir (Turkey) were characterised by X-ray diffractometry (XRD), X-ray fluorescence (XRF) and investigated the blue thermoluminescence (TL) emission of the samples. The TL glow curves exhibited a very complex structure that were analyzed via computerized glow curve deconvolution (CGCD), initial rise (IR) and variable heating rate (VHR) techniques. It could be appreciated how the kinetic parameters (trap depth -E-a-, kinetic order -b- and frequency factor -s- for each electron trap levels) were consistent regardless of the analytical method used.
