Abstract
Infrared stimulated luminescence (IRSL) dating is part of a suite of luminescence dating techniques that exploit past radiation dose accumulated within minerals over geological timescales. IRSL dating is commonly applied to feldspars because the trapped charge populations of these minerals can be easily evicted via stimulation with infrared photons. Feldspar IRSL dating offers several advantages over quartz OSL because of brighter luminescence signals and because signal saturation occurs at higher doses. Although a form of malign signal instability, termed anomalous fading, has discouraged the use of feldspar IRSL dating in the past, a new signal (pIR‐IR) has recently been uncovered that can largely circumvent this problem. As a result, an increasing amount of attention has been paid to using feldspar IRSL for sediment dating purposes over the last decade. This review focuses on IRSL of feldspars and its use for dating, including signal characteristics, development and recent advancements.
