In two cores in the Odiel and Tinto river estuary, Sc, Y, Th and Cu concentrations show a significant increase in the intermediate levels, between 10 and 40 cm depth. Vertical evolution patterns for Sc, Y, Cu and heavy ... -
Asociaciones de foraminíferos bentónicos y evolución paleoambiental del Plioceno inferior en el sector de Elche-Crevillente (Cuenca del Bajo Segura, Alicante): Resultados preliminares
(Sociedad Geológica de España, 2004)Benthic foraminifer assemblages of two Early Pliocene sections located between Elche and Crevillente are studied. In both sucessions three stratigraphic units are distinguished: P0 Unit, littoral conglomerates (transgressive ... -
Aspectos hidrogeoquímicos sobre la relación aguas subterráneas-aguas superficiales en el río Andarax (Almería)
(Sociedad Geológica de España, 2004)The Andarax river is characterized by the variability of its flow, which is dependent upon the rainfall regime of the area. This work presents a study of the chemical composition of the surface waters of the Andarax river ... -
Atenuación de la oxidación del lodo pirítico de la balsa de lodos de Cueva de la Mora (Almonaster, Huelva): ensayos de laboratorio
Pérez López, Rafael; Cama, J.; Nieto Liñán, José Miguel; Ayora Ibáñez, Carlos (Sociedad Geológica de España, 2004)
The addition of alkaline substances is a technique commonly used to prevent acid production generated by the weathering of sulphide-rich sludge. In this work, we show the effectiveness of fly ash, a waste of coal combustion, ... -
Biodisponibilidad de Fe y metales pesados en los sedimentos de la Ría de Huelva (SO de España)
López González, Nieves; Borrego Flores, José; Carro Flores, Berta; Lozano Soria, O. (Sociedad Geológica de España, 2004)
Bioavailability of Fe, Cu, Zn, As, Cd and Pb has been studied in 17 samples of surface sediments of the Ria of Huelva. In all cases, total concentration of these elements is high, especially of Zn (1660,6 ppm), followed ... -
Cambios de distribución del ión fluoruro en el acuífero de la Vega de Granada; consideraciones hidrodinámicas
(Sociedad Geológica de España, 2004)The distribution of fluorides contents in the Vega de Granada aquifer is updated with respect to the situation in the 2003-04 period. The results are compared with those obtained in the 1983-84 period, which was ... -
Caracterización físico-química de las aguas subterráneas de la Sierra de Segura (Cordillera Bética)
(Sociedad Geológica de España, 2004)Periodic control of several physical and chemical data of Sierra de Segura springs has allowed us to determine that cold (from 9ºC to 11ºC) and low salinity (0.25 to 0.35 g/L) calcium and calcium-magnesium bicarbonate ... -
Caracterización hidroquímica de los arroyos que vierten a la Ría de Huelva
Ruiz Cánovas, Carlos; Olías Álvarez, Manuel; Cerón García, Juan Carlos; Nieto Liñán, José Miguel (Sociedad Geológica de España, 2004)
The estuary known as Ría of Huelva receives the flow of two rivers intensely affected by acid mine drainage (AMD), the Odiel and Tinto rivers. The aim of this work is to evaluate the quality and the seasonal variations of ... -
Cartografía geológica de la Reserva Natural Lagunas de Campillos. Hidroquímica y dinámica hidrológica
