The study of glauconite as well as t he host whole rock allows us to identify the glauconite origin discrimintating between its autochthonous or allochthonous provenance. Results suggest an autochtonous and evolved glauconite derived from a condensed section according to Amorosi (1995) criteria}, publisher = {Sociedad Geológica de España}, keywords = {Geochemical}, keywords = {Glauconite}, keywords = {Condensed section}, keywords = {Tortonian}, keywords = {Guadalquivir Basin}, keywords = {SW Spain}, title = {Caracterización geoquímica del horizonte glauconítico en el límite superior de la Formación Niebla (Tortoniense superior, SO España): Datos preliminares}, title = {Geochemical characterization of the glaucony horizon within the upper boundary of Niebla Formation (Upper Tortonian, SW Spain): A preliminary approach}, author = {Abad de los Santos, Manuel and Rosa Díaz, Jesús de la and Pendón Martín, José Gabriel and Ruiz Muñoz, Francisco and González-Regalado Montero, María Luz and Tosquella Angrill, Josep}, }
