Exposure to light reduces the Optically stimulated Luminescence (OSL) signal from quartz and provides the basis for dating the event of light exposure and thus the sedimentation.
Infrared-Radiofluorescence (IR-RF) is a technique for dosimetric dating of potassium feldspar to establish sedimentation ages.
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.
During long transport in fluvial systems the ESR (EPR) signal in quartz grains is sufficiently reduced to allow the determination of the age of sedimentation.
By analysing single mineral entities different dose populations can be distinguished and models derived for different events of e.g. beaching or deposition.
Short light stimulation employs the different decay times of luminescence signals from different minerals in order to detect the luminescence signal predominately from a single mineral.
