Silurian conodont biostratigraphy and carbon (δ[sup.13][C.sub.carb]) isotope stratigraphy of the Victor Mine (V-03-270-AH) core in the Moose River Basin

The Moose River Basin in Ontario, Canada, contains nearly 1 km of Silurian marine strata, and although it has been studied for more than a century, its precise correlation globally has not been constrained. Herein, a core from the Victor Mine in the Moose River Basin was examined for conodont biostratigraphy and carbonate carbon (δ[sup.13][C.sub.carb]) isotope chemostratigraphy to provide a detailed chronostratigraphic framework for the Silurian strata (Severn River, Ekwan River, and Attawapiskat formations) in the Moose River Basin. The recovery of Aspelundia expansa, Aspelundia fluegeli fluegeli, Distomodus staurognathoides, Ozarkodina polinclinata estonica, Pterospathodus eopennatus, and Aulacognathus bullatus, as well as the lower Aeronian, upper Aeronian, lower Telychian (Valgu), and ascending limb of the Sheinwoodian (Ireviken) positive carbonate carbon (δ[sup.13][C.sub.carb]) isotope excursions provide significantly improved chronostratigraphic correlation of Llandovery strata in the Moose River Basin. Le bassin de la riviere Moose (Ontario, Canada) renferme pres de 1 km de strates marines siluriennes et, bien qu'il ait ete etudie pendant plus d'un siecle, sa correlation planetaire precise n'a pas ete etablie. Une carotte de la mine Victor dans le bassin de la riviere Moose a ete examinee pour en determiner la biostratigraphie des conodontes et la chimiostratigraphie des isotopes du carbone (δ[sup.13][C.sub.carb]) dans les carbonates afin d'etablir un cadre chronostratigraphique detaille pour les strates siluriennes (Formations de la riviere Severn, de la riviere Ekwan et d'Attawapiskat), dans le bassin de la riviere Moose. La recuperation Aspelundia expansa, Aspelundia fluegeli fluegeli, Distomodus staurognathoides, Ozarkodina polinclinata estonica, Pterospathodus eopennatus et Aulacognathus bullatus, ainsi que les excursions positives des isotopes du carbone (δ[sup.13][C.sub.carb]) dans les carbonates de l'Aeronien inferieur, de l'Aeronien superieur, du Telychien inferieur (Valgu) et du membre ascendant du Sheinwoodien (Ireviken) ameliorent significativement la correlation chronostratigraphique des strates llandoveriennes du bassin de la riviere Moose.
