Abstract
In this contribution, we propose using the concordia diagram, which was pro posed by Wetherill, to evaluate the discordant values of K-Ar and Rb-Sr min eral ages. The considerable difference between the decay constants of K-40 and Rb-87 allows us to apply Wetherill's model to these systems.
