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. (eds) Impact of the Environment on Human Migration in Eurasia.The significant improvement of the OSL dating method in recent years makes it applicable to objects ranging in age from 0 to 150 000 years (in some cases to 300 000 or more) with a typical accuracy between 5 and 10%.OSL works because all sediments have some natural radioactivity, caused by the presence of uranium, thorium and potassium isotopes in heavy minerals such as zircons.
Luminescence dating is particularly appropriate when radiocarbon dating is not possible (either where no suitable material is available or for ages beyond the radiocarbon age limit) or for applications affected by radiocarbon plateau effects (e.g.
Our standard cost for OSL dating is £550 VAT per sample but prices can vary depending on the nature and number of samples (see our schedule of charges).
Fieldwork (within Southern England) including in-situ radioactivity measurements, sample collection and travel to and from site can be undertaken at a daily rate of £300 VAT.
The typical range for burnt stone or sediment is from about 100 to 300,000 years.
The error limits on the dates obtained are typically in the range of 5 to 10%.
