The bleaching limits of IRSL signals at various stimulation temperatures and their potential inference of the pre-burial light exposure duration
Infrared Stimulated Luminescence (IRSL) techniques are being increasingly used for dating sedimentary feldspars in Youth Barrel Saddles the middle to late Quaternary.By employing several subsequent stimulations at increasing temperatures, a series of post-IR IRSL (pIRIR) signals with different characteristics (stability and bleachability) can be ob
