Abstract

The accuracy of uranium-series dating was studied quantitatively using thenatural long-lived decay chains 4n+2 and 4n+3. An unusually well-boundedmatrix diffusion case was used as the reference for USD simulations. Thesimulations applied the traditional closed and open system models, as wellas detailed multistage models that incorporated the known accumulationhistory of the decay chain members. The results show clearly the improvedaccuracy and consistency in dating with detailed mass flow information.
