Determinación de los valores de fondo regional en sedimentos Holocenos del estuario del río Guadiana (SW de España)
This main aim of this work is the determination of the regional background in Holocene sediments of the Guadiana River estuary. These background values are essential in order to establish the environmental quality of the ... -
Disoluciones e incrustaciones ferruginosas asociadas al OAE 1a en la plataforma carbonatada de La Florida (NO de Cantabria)
(2008)The early Aptian succession of La Florida platform in northwestern Cantabria exhibits two stages of platform carbonates separated by a dissolution surface preceding the drowning of the platform. The dissolution surface ... -
Análisis de la fracturación de la plataforma carbonática de Santanyí, Mallorca. Relación con los paleocolapsos y su cronología
(2008)The up-lift is one of active karst control factor. However, examples of inactive preterits structures in the east coast of Majorca Island could be direct relation with up-lift and fracturation. Regionally, post-Miocene up-lift ... -
Reconstrucción paleoclimática de la plataforma continental gallega basada en datos geoquímicos y magnéticos
(2008)The study of the composition and provenance of the sediments from two cores from the Galician continental shelf (NW of the Iberian Peninsula) based on their textural, geochemical and magnetic properties has allowed us ... -
Nueva evidencia sobre la edad del tránsito endorreico-exorreico de la cuenca de Guadix-Baza
(2008)The Guadix-Baza basin was an endorheic continental basin during the Pliocene and part of the Pleistocene, later being captured by a tributary of the Guadaquivir River which would turn into the Guadiana Menor River. This ... -
El metasomatismo de flúor en la aureola de contacto del skarn de scheelita de Los Santos (Salamanca, NO España)
(2008)Fluorine-bearing minerals such as chondrodite, norbergite, clintonite, chlorite and F-rich mica in the Los Santos dolomite marbles indicate that contact metamorphism was accompanied by F metasomatism. The low HF concentration ... -
Palaeoceanographer, una herramienta informática para estimar características paleoceanográficas de las aguas marinas superficiales del Cuaternario y Neógeno superior
(2008)This work presents Palaeoceanographer as a new computer tool that we designed for palaeoceanographic studies. However, the software utility can be also extended to other scientific areas in which the aim is to carry out ... -
Diferencias mineralógicas y geoquímicas del vulcanismo inicial de Fuerteventura
(2008)The initial growth stage of the Fuerteventura Island is represented by submarine, transitional and subaerial volcanics. Among the submarine types, two can be distinguished: a basaltic (s.l.) one, and a basanitic one. The ... -
Caracterización hidrogeoquímica preliminar de las aguas subterráneas del acuífero carbonático de la Sierra de Aracena (Huelva)
(2008)The groundwater resources of the aquifer of the Aracena mountain range (Huelva) are being studied in detail by the Spanish Geological Survey. In these studies the hydrochemistry plays a pivotal role and contributes to ... -
Rutilos ricos en Zr incluidos en granates de xenolitos granulíticos de la corteza inferior del Sistema Central Español: implicaciones geodinámicas
(2008)Two petrographic types of rutile are observed in the peraluminous felsic meta-igneous granulites, the most common type of the lower crustal xenolith suite of the Spanish Central System (SCS). Rutile-1 (Rt-1) corresponds ... -
Sistema de canales submarinos en una rampa de carbonatos templados, Cuenca de Sorbas, sureste de España
(2008)Temperate carbonates with abundant remains of braquiopods and bivalves deposited in a carbonate ramp developed at the northern margin of the Sorbas Basin during the latest Tortonian-earliest Messinian. Small submarine ... -
Caracterización de la sedimentación Lago Mare (Messiniense terminal) y de la transgresión del comienzo del Plioceno en la cuenca de Málaga (Cordillera Bética)
(2008)A stratigraphic unit deposited close to the Messinian-Pliocene boundary is newly discovered in the Malaga basin. This unit mainly consist of alluvial and lagoonal deposits. Paleontological and paleomagnetic data from ... -
Microcodium en calizas del Eoceno Medio (Luteciense) de la Sierra de la Pila (Prebético Interno, Murcia)
(2008)Microcodium is a calcitic microfeature, mainly interpreted as root calcification products of terrestrial plants on carbonate-rich substrates, that is abundant in Paleogene successions of the peri-Tethyan realm. In the ... -
Formación del placer de la playa de Montalvo (Pontevedra)
(2008)In Montalvo beach (Pontevedra) a concentration of heavy minerals forming a placer takes place. The placer formation is related to the beach hydrodynamics that concentrates and segregates the different particles in layers. ... -
Clinoformas progradantes en el Prebético de Jaén. Albiense terminal-Cenomaniense basal, Serrezuela de Pegalajar, Jaén. Significación paleogeográfica
(2008)Progradational clinoforms of platform limestones of the Caliza de Jaén Formation in the Serrezuela de Pegalajar, Prebético de Jaén, sited just to the southeast of Jaén city are here described and a first broadly approach ... -
Análisis y distribución de hidrocarburos policíclicos aromáticos (PAH´s) en suelos y aguas de escombreras en Puertollano (Ciudad Real)
(2008)The aim of this study was to examine if the soils and waters of Puertollano area are affected by pollution of polycyclic aromatic hydrocarbons (PAHs) and their quantification. The results show that PAHs concentrations are ... -
Consideraciones sobre la hidrogeología y la hidrogeoquímica de la Dorsal Calcárea de la región de Tetuán (Rif septentrional, Marruecos)
(2008)Limestone and dolomite, belonging to the Calcareous Dorsal, constitute very important karstic aquifers in the region of Tetouan (North of Morocco). The main objective of this study is to characterize the hydrogeology and ... -
Análisis del plegamiento al Norte de Biescas (Zona Surpirenaica, Pirineos centrales)
(2008)This paper provides the first results of a structural study in a cross-section in the Central Pyrenees (South Pyrenean Zone, North of Biescas), bordered on the north by Palaeozoic rocks of the Axial Zone. The geometric ... -
Las «minas de agua» de Ciempozuelos (Madrid)
(2008)Ciempozuelos is located to the south of Madrid on the Miocene gypsum formations. From old times (XIV century or former) the water supply was made mainly by means of dug galleries (denominated «mines» of water). Given the ... -
