Alteración diagenética en conchas de rudistas Monopleúridos del Complejo Urgoniano de Ereño (Aptiense – Albiense Inferior, Bizkaia)
(2006)Cathodoluminescence and microprobe analysis in monopleurid shells from Aptian – Lower Albian limestones in Ereño (Bizkaia) has allowed to us to realize that different rudist shells show different diagenetic responses in ... -
Análisis bioestratigráfico del Eoceno Inferior de la sección de Barinatxe (Pirineos Occidentales) mediante nanofósiles calcáreos
(2006)The Barinatxe section (Western Pyrenees) contains one of the most complete and expanded deep-water succession of the early Eocene so far described. The succession, cropped out continuously along sea cliffs, is rich in ... -
Aplicaciones geotermobarométricas de los contenidos en elementos trazas de minerales granulíticos: Zr en rutilo y HREE en granate de los xenolitos félsicos de la corteza inferior del Sistema Central Español
(2006)Geothermobarometric estimations based on the trace element concentration of minerals from lower crustal peraluminous felsic granulite xenoliths from the Spanish Central System (SCS) have been performed. Zr in rutile ... -
Biometría de Strombus bubonius Lamark 1791 del yacimiento de Cerro Largo (Roquetas de Mar, Almería)
(2006)This paper deals with a comparative metrical study of the mesogastropods Strombus bubonius and Strombus latus. The former from the raised marine deposits of Cerro Largo (Roquetas de Mar, Almería) of Middle Pleistocene ... -
Caracterización geológica de los afloramientos de El Pimpollar, extremo nororiental de la Zona Surportuguesa
(2006)Two volcanic units can be distinguished in the “El Pimpollar” outcrop (eastern South-Portuguese Zone). The Lower Unit is composed mainly of submarine dacites and andesites, with some subordinated basalts and trachyandesites. ... -
Caracterización morfo-estructural del borde occidental de Sierra de Gádor (Cordillera Bética)
(2006)An integrated geomorphic and structural study has been performed along the western border of Sierra de Gádor (Betic Cordillera, SE Spain). To do this, we have calculated some of the most reliable geomorphic indexes for ... -
Caracterización sísmica del Anticlinorio del Bajo Segura (Alicante): Fallas del Bajo Segura, Torrevieja y San Miguel de Salinas
(2006)This paper presents a seismic characterization of the most important faults of the Lower Segura Anticlinorium. Available evidence of quaternary faulting, as well as the characteristics of the seismic record in the area, are ... -
Cartografia geoambiental aplicada a la gestion de residuos del Espacio Natural Protegido «Las Batuecas – Sierra de Francia». (Salamanca-España)
(2006)The human activity generate waste that finally go to controllable and uncontrollable landfill. In this case, the emplacement of uncontrollable landfill is analized with parameters of environmental geology, using thematics ... -
Clasificación geomecánica de macizos pizarrosos en el sinclinal de Truchas
(2006)Rock mass characterization and classification are significant in geological investigations involving engineering works and in the field of applied geology. Discontinuities characterization and rock properties determination are ... -
Comparación de métodos de interpolación para la realización de mapas de precipitación para el acuífero de Icod-Cañadas (Tenerife, Islas Canarias)
(2006)Groundwater is the main water resource in Tenerife (Canary Islands) where it represents almost 90% of the consumption. For the Insular Hydrological Plan the most important aquifer in the future will be the one located in ... -
Composición y evolución de las lavas de la isla de Branco (Cabo Verde)
(2006)The first data about the composition of lava flows from Branco Island (Cabo Verde) are presented in this work. Most lava flows in the sequence are alkali basalts (Fo84-76 olivine, En44-36 diopside, An83-31 plagioclase) showing ... -
Contribución del estudio estructural del enjambre de diques básicos del Precámbrico del Anti-Atlas al conocimiento de su significación geotectónica en la orogenia panafricana
(2006)The Precambrian inliers in the Anti-Atlas of Morocco are extensively intruded by swarms of dolerite dykes. On the basis of detail analysis of foliation patterns around dykes from Kerdous and Zenaga inliers it is inferred ... -
Cronoestratigrafía de los registros aluviales del tránsito Pleistoceno superior-Holoceno en la depresión de la Bardena Blanca (Navarra)
(2006)In this work, preliminary chronostratigaphic features of the Upper Pleistocene-Holocene morphosedimentary alluvial unit covering the bottom of the Bardena Blanca depression are described. This unit is made up by 1) gravels ... -
Desarrollo simultáneo de pliegues, esquistosidad y cabalgamientos en el Eoceno inferior de Isaba (Valle del Roncal, Pirineo navarro)
(2006)Geometric and kinematic analysis of Pyrenean folds, cleavage and thrusts is carried out in several exceptional outcrops of the Eocene flysch at Isaba (Navarra, Spain). Distribution, orientation and cross-cut relationshi ... -
Diagénesis y estratigrafía secuencial de la arenisca «U» de la Fm Napo del Oriente, Ecuador

Distribución areal y ecología de las asociaciones de ostrácodos recientes en la marisma Joyel (Cantabria)
(2006)Recent ostracod assemblages of the Joyel marsh (Cantabria, N Spain) are described. Eigteen species are living in this marsh. The strongly eurihaline species Loxoconcha elliptica dominates the assemblages in the most of ... -
El Deslizamiento de Güevéjar (provincia de Granada): un caso de inestabilidad de laderas inducida por sismos
(2006)Drawing on historical documents and a detailed field study, we have been able to characterize the Güevéjar landslide as a complex landmass movement with a dominant multi-rotational component. The landslide body is made ... -
El Edificio Antiguo de la isla de San Vicente (Cabo Verde): características del sector occidental
(2006)A more than 1000m thick pile of basaltic lava flows and pyroclasts dipping seawards rises on the western sector of San Vicente. Several systems of dikes cut across the succession that is composed of two different sequences. ... -
