• Resumen

  • A preliminary absolute chronology for the Quaternary calcareous tufa deposits from the Piedra River valley (Iberian Range, NE Spain) has been carried out based on U series dating, Amino Acid Racemization, Optically Stimulated Luminescence and Radiocarbon dating techniques. Although the age uncertainties of the obtained dates are substancial, four stages of tufa accumulation correlated to MIS 9, 7-6, 5 and 1 can be distinguished. The most favourable period for tufa accumulation is located around the isotopic stage 7.
