This study investigated the applicability of optical dating, using coarse-grained quartz, to provide a chronology of these sediments.

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.

Overall, 28 samples extracted from the upper 50 m of core YZ07 were investigated.Turnaround time is several weeks to several months and very dependent on the time taken to prepare the samples, with organic rich samples taking the longest. All sediments contain trace minerals including uranium, thorium and potassium.These slowly decay over time and the ionising radiation they produce is absorbed by other constituents of the sediments such as quartz and feldspar.Jon Olley does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond the academic appointment above.Griffith University provides funding as a member of The Conversation AU.
