Research of Klaudia Kuiper

Direct intercalibration of radio-isotopic 
and astronomical time in the Mediterranean Neogene
This postdoc research project constitutes the next crucial and fundamental step in a rigorous attempt to intercalibrate the two completely independent - astronomical and radio-isotopic - absolute dating methods. Main objectives are:
  • to solve remaining inconsistencies in the astronomical - 40Ar/39Ar intercalibration;
  • to intercalibrate the 40Ar/39Ar and astronomical dating systems with the U/Pb system;
  • to reduce current uncertainties in 40Ar/39Ar dating by introducing a direct astronomically dated sanidine standard suitable for laser probe 40Ar/39Ar dating;
  • to apply the astronomically standard to accurately date magneto- stratigraphically well constrained volcanic layers of Paleogene age. 
We introduce a direct astronomically dated mineral standard in 40Ar/39Ar dating and aim at the intercalibration of the astronomical and 40Ar/39Ar time scales with the U/Pb system. We will apply the new standard to date volcanic ash beds of Paleogene age, for a critical independent check on the tuning of cyclic sequences of that age.
