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.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.

This is done in collaboration with the University of Oxford Luminescence Dating Laboratory.

Stimulating samples using infrared light causes luminescence, the intensity of which varies depending on the amount of radiation absorbed.

Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.

The basic cost is £550/sample plus reporting time based on your requirements.

The report will contain OSL results calibrated for sample water content and salinity.
