Although almost universally ignored, the effect of errors in the uranium decay-constants on U–Pb concordia-intercept ages (and Pb–Pb ages) are significant, and not equivalent to those of simple U–Pb ages. Equations are derived for concordia-intercept age-errors that take decay-constant errors into account.
