Contrairement à l'uranium, le thorium est insoluble dans l'eau. L'eau de mer (ou toute eau courante) contient donc de l'238U en équilibre séculaire avec son descendant 234U (à de très faibles teneurs : 3 mg/d'uranium par mètre cube d'eau de mer), mais ne contient pas de thorium, qui précipite quand il est formé.

Lead-lead dating (Pb-Pb dating) is a method for dating geological samples, normally based on 'whole-rock' samples of material such as granite. For most dating requirements it has been superseded by uranium-lead dating (U-Pb dating), but in certain specialized situations (such as dating meteorites and the age of the  U-pb dating (Early to Middle Eocene) based on U/Pb dating of neoformed rims of zircons (Spandler et al., 2005). The retrograde stage corresponds to the exhumation of the Pouébo unit across the unroofed Diahot unit, in an extensional context (Cluzel, 1995).
