“…3). This peak is one of the oldest episodes of natural pollution in southwestern Europe and has been detected in other cores of the Tinto River estuary (Arroyo et al 2021). This small peak may be due to the coincidence of the Holocene flooding and the weathering/oxidation of the mineral deposits concentrated in the Iberian Pyrite Belt, a process that began in the Oligocene (Essalhi et al 2011).…”

“…The correlation with other cores collected in the middle estuary of the Tinto River estuary (Ruiz et al 2020, Arroyo et al 2021) can be used to obtain a synthetic paleoenvironmental evolution of this sector since the Upper Pleistocene, with four main phases: a) the Upper Pleistocene, when the fluvial network eroded the Neogene marine formations and created several coves on a Miocene substrate; b) the Lower Holocene (ca. 10-6.5 kyr BP), with the deposits of alluvial, sandy sediments: c) the Holocene transgression (ca.…”

“…1, A: Gibraleón) o de testigos que abarcan su tramo medio y superior (Fig. 1, A: Huelva, Palos de la Frontera) revela un predominio muy acusado de limos arcillosos (limos: 50-75%; arcillas <15%) sobre las arenas, que no suelen alcanzar el 25% (Abad et al, 2007;Arroyo et al, 2021;Abad et al, 2022;Romero et al, en prensa). Esta distribución contrasta con los similares porcentajes de ambos o mayores porcentajes de arenas observados en la UAT (Fig.…”

“…Una comparativa entre el contenido en elementos traza y tierras raras de esta unidad y diversos estudios realizados en diferentes secciones superficiales y testigos que incluyen a sedimentos de la FAG permite establecer sus singularidades geoquímicas (Tabla 2). La UAT presenta menores concentraciones medias de la mayoría de los elementos traza que el resto de esta formación, con valores significativamente más bajos de Ba (UAT: 50,8-73,8 ppm; FAG: 150-360 ppm), Sr (UAT: 42,4-132 ppm; FAG: 187,3-293,3 ppm) y U (UAT: 1,02-1,31 ppm; FAG: 2-3,2 ppm) (González de Canales, 2017; Arroyo et al, 2021;Arroyo, com. pers.…”
