Sediment dating

When sediments cover an archaeological site they are exposed to light and the mineral grains are bleached. Such events can be dated by luminescence methods and the age employed to determine the age of an archaeological site through its related sediments.

  • Optically Stimulated Luminescence (OSL, TT-OSL) dating of quartz grains from sediments

  • Infrared Stimulated Luminescence (IRSL, pIRIR, IR-RF) dating of feldspar grains from sediments

  • Trench sediment filling with OSL/IRSL

  • With a suite of stimulation wavelengths the lexyg devices provide an all in one solution for many sediment and mineral types
