Noun

concordia (countable and uncountable, plural concordias or concordia)

1. (geology, geochronology) A set of plotted points, appearing as a curve on a concordia diagram or isochron diagram, representing sample data from rock of the same age; the condition of being a member of said set (or on said curve).
   • 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 $\mathrm{U}-\mathrm{T}\mathrm{h}-\mathrm{P}\mathrm{b}$ concordias are not significant in terms of geological time, merely changes which took place in the $\mathrm{T}\mathrm{h}/\mathrm{U}$ 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 $\mathrm{U}$ 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 ${\phantom{A}}_{\phantom{}}^{\phantom{231}}{\phantom{A}}_{\phantom{2}}^{\phantom{2}231}\mathrm{P}\mathrm{a}-{\phantom{A}}_{\phantom{}}^{\phantom{230}}{\phantom{A}}_{\phantom{2}}^{\phantom{2}230}\mathrm{T}\mathrm{h}$ concordia diagrams are similar to the responses of $\mathrm{P}\mathrm{a}-\mathrm{T}\mathrm{h}$ concordias presented in Section 10.5a.
