   1994 [1988 Elsevier], H.-G. Attendorn, R. Bowen, Isotopes in the Earth Sciences, Chapman & Hall, page 131, Such lower intersections of resultant discordias with U-Th-Pb concordias are not significant in terms of geological time, merely changes which took place in the Th/U ratios or lead isotope ratios through the factors alluded to above.

   The addition of U to a carbonate sample on concordia causes the point to move off concordia in the direction of the origin.[…]The patterns that develop in the ^{₂₃₁}Pa-^{₂₃₀}Th concordia diagrams are similar to the responses of Pa-Th concordias presented in Section 10.5a.
