Estudio comparativo de diferentes métodos de interpolación para la realización de mapas de precipitación en la isla de La Gomera (Islas Canarias): Evaluación de la incorporación de la altura
(2007)Groundwater is the main water resource in La Gomera (Canary Islands) where it represents almost 70% of the consumption. Since the elaboration of the preliminary works of the Insular Hydrological Plan in 1996 there has ... -
Características físico-químicas de las aguas superficiales afectadas por drenaje ácido de minas en el sector meridional de la cuenca del Guadiana (Suroeste de la Península Ibérica)
The southern sector of the Guadiana basin drains the central-western part of the Iberian Pyrite Belt (FPI), an area with many polymetallic sulphide deposits and residues of the mining activity, generating an acidic leach ... -
Estudio diagenético en conchas de braquiópodos de la cuenca del Guadiato (Mississippiense, SO del Macizo Ibérico)
(2007)Detailed petrographic and geochemical analyses of brachiopod shells from the Guadiato Carboniferous basin (Córdoba, SW Iberian Massif) has been carried out in order to evaluate their textural and geochemical preservation degree ... -
Using multiple geochemical proxies to trace origin of gypsum (Gulf of Carpentaria, Australia, -70ka)
(2007)Los cambios en el nivel del mar y las asociadas fluctuaciones climáticas provocaron cambios cíclicos y extremos en los ambientes deposicionales en la región del Golfo de Carpentaria (N, Australia). La desconexión con el ... -
Aplicación del modelo hidrológico SWAT a la cuenca del río Meca (Huelva, España)
Galván González, Laura
; Olías Álvarez, Manuel; Fernández de Villarán San Juan, Rubén; Domingo Santos, Juan Manuel (2007)
Acid mine drainage (AMD) is the main pollutant source in the Odiel river basin (SW Spain). Stream-flow data constitute a tool to assess the pollutant load transported by the drainage network, as well as to evaluate the ... -
A propósito de la alteración de una variedad comercial de una granulita de Brasil en una plaza pública del norte de Marruecos
(2007)The aim of this study is to explain the natural processes that led to the intense alteration observed in a commercial variety of Brazilian granulite named as «Granito Verde Eucalipto» paving a public square in Morroco. ... -
Precisiones sobre la edad, mediante ammonoideos y nautiloideos, de la Fm. Margas del Forcall en la subcuenca de Oliete (Cadena Ibérica, España)
(2007)Ammonoids and nautiloids from Margas del Forcall Formation, located in the Oliete sub-basin (Iberian Chain), were studied. Taphonomic, sedimentologic and biostratigraphic analyses were carried out. The fossil record of ... -
Deformación cenozoica de la litosfera Ibérica: Sistema Central y cuencas del Duero y Tajo
(2007)The Cenozoic deformation of the Iberian lithosphere along a NW-SE profile from the northern Duero Basin to the southern Tajo Basin, crossing Spanish Central System, has been analysed by means of a numerical simulation ... -
Nuevas aportaciones al registro paleoicnológico en Cabezón de Cameros (La Rioja. España)
(2007)Cabezon de Cameros is a well known place for paleoichnological workers because one of the first described iguanodontid cuadrupedal trakways was found there. Up to now, this was the only site known in this place. In this ... -
Huellas de dinosaurios conservadas en materiales del cortejo transgresivo en cauces encajados. Jurásico superior y Cretácico inferior de Alpuente, Valencia
(2007)The upper Jurassic and lower Cretaceous deposits of the Southwestern Iberian Basin at Alpuente (Valencia) contain abundant remains of dinosaurs, including several localities with footprints. In this area deltaic ... -
Análisis de la geometría en profundidad de fracturas conductoras en zonas de baja permeabilidad mediante tomografía eléctrica (El Berrocal, Sistema Central Español)
(2007)The groundwater flow in zones of low permeability, as granites, is mainly associated with zones of fracture. For this reason the characterization of the fractures is fundamental, both in surface as in depth, and must integrate ... -
El cabalgamiento cenozoico de Boinás (Cordillera Cantábrica, España)
(2007)The opencast gold mine of Boinás, has allowed to outcrops the contact between the variscan basement and the Cenozoic sediments. It is observable that the contact is a post - Lower Oligocene thrust, with a N40ºE trend. ... -
