Many types of sediment do not contain quartz and for dating the light exposure to light of such sediments Infrared stimulated Luminescence (IRSL) is used.
Due to higher saturation doses the age range is larger than for OSL
Internal dose rates in K-feldspar reduce dependency on external dose rate and water content
Might suffer from an anomalous signal loss which leads to age underestimation
Post-Infrared Infrared luminescence (p-IRIR) allows the dating of Middle Pleistocene sediments
