Análisis de un nuevo registro micropaleontológico en el margen meridional del archipiélago de las Svalbard (océano Ártico): resultados preliminares e implicaciones paleoceanográficas
(2009)Preliminary results of micropalaeontological analyses carried on samples from a sediment core recovered in summer 2007 in the Storfjorden area (SW Svalbard margin, Arctic Ocean) reveal changes in the concentrations of ... -
Anthropocene versus Holocene relative sea-level rise rates in the southern Bay of Biscay
(2009)Con el fin de evaluar la aceleración en el ascenso relativo del nivel marino durante el Antropoceno, se han comparado los resultados previamente establecidos para el siglo XX con los resultados obtenidos a partir del ... -
Aplicación conjunta de Georradar y Tomografía eléctrica para la evaluación del riesgo de colapso en la Sima de Madrona (Segovia)
(2009)Carbonate rocks are frequently affected by dissolution from rainfall and groundwater. As dissolution progress, the roof of the cavities can rapidly collapse originating landforms named sinkholes. When this kind of ... -
Aplicación del análisis multi-espectral para el reconocimiento automatizado de menas metálicas
(2009)Traditional identification of ore minerals with reflected light microscopy relies heavily on the experience of the observer. Qualified observers have become a rarity, as ore microscopy is often neglected in today’s university ... -
Aplicación del método electromagnético de inducción ligera para el análisis de la permeabilidad en medios fracturados (granito de "El Berrocal", Sistema Central Español)
(2009)Fracture characterization in granites has been an important subject of study during these last years, by means of geological-structural cartography, hydrogeology and geochemical analysis. These works have been carried ... -
Aportaciones de un nuevo yacimiento de icnitas saurópodas de la Formación Camarillas (Barremiense inferior, Galve, Teruel)
(2009)Important sites of direct and indirect dinosaur fossils can see in the Galve area. This paper shows the sauropod footprint structures found in a new ichnite outcrop in the Cabezo de San Cristobal. The tracksite is situtated ... -
Asociaciones de foraminíferos bentónicos recientes en la plataforma marina de las Guayanas
(2009)A total of 183 benthic foraminiferal species have been identified in the continental shelf of Guianas, being the most abundant: Ammonia beccarii, Ammonia tepida, Eponides repandus, Fursenkoina schreibersiana, Hanzawaia ... -
Características dinámicas del canal hidráulico ASSUT-1
(2009)An initial study of hydraulic characteristics of the ASSUT-1 channel has been produced and the results are presented here. This experimental equipment was created in order to develop studies in the modelling of transport ... -
Caracterización geoquímica de la balsa de lodos de la mina de San Quintín, Ciudad Real
(2009)The geochemical characterization of the San Quintín mine pond is the aim of this study. This kind of waste deposits represents large accumulations of reactive minerals and subsequently, emission sources of heavy metals ... -
Caracterización geoquímica del petróleo de los reservorios de la Fm Napo del Cretácico (Ecuador) y su relación con las lutitas intercaladas como roca generadora de hidrocarburos
(2009)The Napo Formation from the Cretaceous age is located in the Oriente basin in Ecuador and is composed of limestones, shales, and sandstones, the «U» and «T sandstones», which are the most important reservoirs in the ... -
Caracterización geoquímica y ambiente geodinámico de génesis de las metabasitas de la Sierra del Algarrobo (Cordillera Bética oriental)
(2009)The metabasites cropping out in the Sierra del Algarrobo have been studied from petrological and geochemical points of view. They consist of gabbros, dolerites and basalts, which were transformed into eclogites or ... -
Caracterización geoquímica y encuadre geodinámico de las anfibolitas y eclogitas del manto de Ojén, Complejo Alpujárride, Cordilleras Béticas
(Sociedad Geológica de España, 2009)Amphibolite bodies with eclogite relics are found interlayered between the Ojen nappe´s crustal rocks, below the Ronda peridotites of the Betic Cordilleras (southern Spain). We present a geochemical study of such ... -

(2009)A fragment of a distal caudal vertebra that is assigned to a sauropod titanosaur is described. The fossil comes from an outcrop of the Villalba de la Sierra Formation in Sacedón (Guadalajara), which is considered to the ... -
Comparación del método de Newmark a escala regional, local y de emplazamiento: el caso del desprendimiento de la Paca
(2009)The Lorca Basin (Murcia) is located in one of the most seismically active regions of Spain. This area is very interesting for studying earthquake-induced slope instabilities as there are well known cases associated to ... -
Composición isotópica de gasterópodos en secuencias aluviales holocenas de Bardenas Reales (Navarra): implicaciones paleoambientales
(2009)Stable isotope composition of five species of gastropods from the Late Holocene alluvial record was studied in Bardenas Reales Natural Park (Navarre province) in order to deduce palaeoenvironmental information. Snails ... -
Consideraciones hidrogeoquímicas sobre el acuífero detrítico costero de Bou Ahmed (Marruecos)
(2009)The salinity of the waters of the detritic aquifer of Bou Ahmed (Morocco) is very diverse. Based on their hydrogeochemistry, two types of water have been differentiated. The less saline group of waters (electrical ... -
Contribución al conocimiento de la geología del depósito de Au-Cu de "La Pava" (Península de Azuero, Panamá)
(2009)The «La Pava» Au-Cu deposit is hosted by a vulcanosedimentary sequence, named Ocú Formation, developed in an island arc environment that resulted from the subduction of the Nazca Plate beneath the Caribbean Plate during ... -
