Optically-stimulated luminescence is a late quaternary dating technique used to date the last time quartz sediment was exposed to light. As sediment is transported by wind, water, or ice, it is exposed to sunlight and zeroed of any previous luminescence signal.

Quartz osl dating of late quaternary chinese and serbian loess: a cross- eurasian comparison of dust mass accumulation rates.
Quartz optically stimulated luminescence and k‐feldspar post‐infrared infrared stimulated luminescence methods were used to date these shoreline features. The reliability of the dates was confirmed using internal checks of luminescence characteristics and by comparing the quartz and k‐feldspar ages.

Most luminescence dating methods rely on the assumption that the mineral grains were sufficiently bleached at the time of the event being dated. For example, in quartz a short daylight exposure in the range of 1–100 seconds before burial is sufficient to effectively “reset” the osl dating clock.
Results obtained for quartz grains, which are regarded as being the most reliable in luminescence dating.
Optically stimulated luminescence (osl) dating methods have been widely applied in quaternary glaciology. However, glacigenic deposits are considered in general as problematic for osl dating, mainly because they are transported shorter distances prior to burial and are usually partially bleached.
The purity of the quartz extract is primal for effective dating because a small amount contamination (1%) by potassium feldspar and other minerals can dominate the luminescence emissions. Multiple soaks in hf may be needed to obtain a pure quartz separate.
Along the ne pamir margin, flights of late quaternary fluvial terraces span actively deforming fault-related folds. We present detailed results on two terraces dated using optically stimulated luminescence (osl) and cosmogenic radionuclide 10be (crn) techniques.
A multiple-aliquot, two-part, regenerative-dose protocol, has been developed as a recuperated osl dating method to extend the application of luminescence dating further back in time. Using the protocol the recuperated osl signal is separated and used to estimate the equivalent dose for fine-grained quartz in chinese loess.
The suitability of quartz optically stimulated luminescence (osl) and feldspar infrared stimulated luminescence (irsl) for the direct dating of phreatic eruptions was tested on examples from the eifel volcanic field, germany.

Quartz is presently the mineral favoured for dating by many luminescence specialists.
A sensitivity-corrected multiple aliquot regenerative-dose protocol has been developed for fine-grained quartz osl dating of chinese loess. Its reliability has been assessed on the basis of the methodology and by dating reference samples of known age close to the transition from the last interglacial paleosol (s 1) to the last glacial loess (l 1), which corresponds to the marine oxygen isotope.
