Suitable for samples up to about 150Ka containing quartz. Ideal for young sediments with no biogenic material present or where the age of the sediments exceeds the range of 14C dating (c. Requires precise measurement of sample water content and salinity.
Osl dating sediments married but still dating
From this data a complex deposition and incision history is constructed for the last 500 years.
It is concluded that sediment deposition was mainly forced by sediment supply from ploughing areas.
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.

It is useful to geologists and archaeologists who want to know when such an event occurred.
It uses various methods to stimulate and measure luminescence.
This is done in collaboration with the University of Oxford Luminescence Dating Laboratory.
Although a relatively new technique, particularly in subaqueous sediments, Strata Data have pioneered its industrial application in dating superficial seabed deposits for geohazard risk assessment.
Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.
