Tooth enamel and quartz grains

Archaeological sites often contain teeth from animals or humans or the site is contained in quartz bearing sediment. The enamel can be dated with Electron Spin Resonance (ESR or EPR), but it is often required to combine this method with U-series dating.

  • Tooth enamel to date an archaeological site

  • Quartz grains to date the sedimentation which covers a site or is related to the archaeology

  • Magnettech's high sensitivity ESR spectrometer MS 400 and MS 5000
