The age of most Lower Austria loess deposits is unknown; this is especially true for Middle Pleistocene loess because there is no generally applicable dating method available. Recently it has been shown that infrared stimulated luminescence (IRSL) signals measured at elevated temperatures after an infrared (IR) stimulation are more stable than the standard IRSL signal measured at 50°C. These signals offer new opportunities to extend the datable age range by minimising or circumventing the undesirable...
