In this study, uranium-series dating of peat in Central and Northern Europe is reviewed including new thermal ionisation mass spectrometry (TIMS) 230Th/U dating results from recently investigated interglacial peat horizons in Central Europe. The activity ratio is a measure of the time elapsed since the formation of the peat. Uranium-series dating methods are based on the radioactive disequilibrium between 238U and its radioactive daughter elements and the re-establishment of equilibrium. Uranium-series dating methods can provide a reliable and precise chronological frame for peat of the past 500000 years. Interstadial and interglacial peat layers are widespread in the Northern Hemisphere and enable us to reconstruct the vegetation history.
