TO THE PROBLEM OF PALAEODOSIMETRICAL INFORMATION STABILITY IN ALKALI FELDSPARS
Galina Hütt, Ivar Jaek · Proceedings of the Estonian Academy of Sciences Geology · 1997
The stability of holes of the centres of recombination in alkali feldspars, extracted from sediments, is studied.For the emission centres with 410 and 570 nm the energy of activation of thermal quenching is obtained (>2eV).Problems of fading and difference between thermoluminescence (TL) and optically stimulated luminescence (OSL), as well as bleachabilities, are discussed.The applicability of the orange band of emission (570 nm) for dating is recommended for future study.
