AB The REE concentration in the water of the Tinto river decreases from the fluvial sector (1098.63 μg·l-1) tothe zone of greater marine influence (0.33 μg·l-1) showing a strong longitudinal gradient in the estuarinemixing zone, where conductivity goes from 10 to 50 mS·cm-1 and pH from 3 to 6. The fluvial sector showsa typical fractionation pattern of acid environments, with a convex morphology centered in the Gd. Inagreement we approached the marine sector of the estuary, with conductivities greater than 50 mS·cm-1and pH bigger than 6, this model evolves towards a fractionation pattern with a clear depletion in LREEthat preferably are adsorbed on the particle surfaces
