Infrared stimulated Luminescence dating

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.

Infrared stimulated Luminescence (IRSL) dating

IRSL-signals of a single aliquot from a SAR protocol applied to polymineral loess
  • 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
