Plot of U-EF vs. Mo-EF for the GL samples showing the oxygenation conditions in the Aptian to Lower Albian of the Marnes Bleues Fm. The SW lines corresponds to the Mo/U molar ratios similar to the seawater value (SW ∼ 7.5–7.9) and the dashed lines correspond to the fractions thereof (3xSW, 0.3xSW). The pattern of U and Mo EFs are compared to the model proposed in Algeo and Tribovillard (2009).
Tracé de U-EF vs. Mo-EF pour les échantillons GL montrant les conditions d’oxygénation dans l’Aptien à l’Albien inférieur des Marnes Bleues Fm. Les lignes SW correspondent aux rapports molaires Mo/U similaires à la valeur de l’eau de mer (SW ∼ 7,5–7,9) et les lignes en pointillés correspondent à leurs multiple ou fraction (3xSW, 0,3xSW). Le modèle des FE U et Mo est comparé au modèle proposé dans Algeo et Tribovillard (2009).
