** 1979, Contributions to Geology, Volumes 17-19; Volume 3, University of Wyoming, page 174:Points above concordia indicate uranium loss and those below indicate uranium gain.
** 1994 [1988 Elsevier], H.-G. Attendorn, R. Bowen, Isotopes in the Earth Sciences, Chapman & Hall, page 131,
    Such lower intersections of resultant discordias with ${\ce {U-Th-Pb}}$ concordias are not significant in terms of geological time, merely changes which took place in the ${\ce {Th/U}}$ ratios or lead isotope ratios through the factors alluded to above.
** 2005, Gunter Faure, Teresa M. Mensing, Isotopes: Principles and Applications, 3rd edition, Wiley, page 521:The addition of ${\ce {U}}$ 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 ${\ce {^{231}Pa-^{230}Th}}$ concordia diagrams are similar to the responses of ${\ce {Pa-Th}}$ concordias presented in Section 10.5a.
