Les reconstitutions passées de la composition isotopique en Sr (87Sr/86Sr) des squelettes carbonatés d'organismes marins (MCS) sont très largement utilisées par les chimiostratigraphes et les paléoenvironnementalistes car elles permettent de reconstituer les variations du rapport 87Sr/86Sr de l'océan au cours des temps géologiques. Les reconstitutions paléoenvironnementales et les datations chimiostratigraphiques reposent sur le consensus que les MCS précipitent leurs tests carbonatés à l'équilibre isotopique avec l'eau de mer qui est homogène à l'échelle globale en raison d'un temps de résidence du Sr (2 Ma) supérieur au temps de brassage océanique (1600 ans). Leur fiabilité en tant qu'outils chimiostratigraphiques peut être remise en ques...
