Reseña preliminar sobre el hallazgo de diáspora asociada a la serpentinización de los macizos de peridotitas de Ronda
(2009)We report the presence of large aggregates (diameter > 1 cm) of diaspore related to the serpentinization of the Sierra Alpujata massif of the Ronda peridotites (Betic Cordilleras, southern Spain). The diaspore is found ... -
Registro geológico del máximo térmico del Paleoceno-Eoceno en el Parque Nacional de Ordesa y Monte Perdido (Pirineo Central)
(2009)The Paleocene-Eocene thermal maximun (PETM) had earlier been documented in basinal and continental settings of the Pyrenean basin clastic units. In this work new data are added from comparatively less well-known platform ... -
Redescubrimiento de uno de los primeros restos de dinosaurio del registro español
(2009)The information of one of the dinosaur fossils collected by Juan Vilanova y Piera at the end of the XIX century in Mora de Rubielos is updated. MNCN 80000 is an pedal phalanx of an Iguanodontoidea dinosaur found between ... -
Reconstrucción de las condiciones paleoambientales del depósito Pñ (Macizo de Peñalara, Sierra de Guadarrama. Madrid), durante los últimos 2.000 años, a partir del contenido en microfósiles no polínicos (NPPs)
(2009)The content in non-pollen palynomorphs (NPPs), constitutes an important tool at the time of reconstructing the paleoenviromental changes of a deposit and explaining them in terms of climate and/or anthropic activity. This ... -
Presencia de cenizas y lapilli esferoidales con estructura interna concéntrica (i.e. pelletal lapilli o spinning droplets) en la tefra del volcán Cabezo Segura (Región Volcánica de Calatrava, Ciudad Real)
(2009)The Cabezo Segura volcano is located in the central part of the Calatrava Volcanic Province. Some deposits of this volcano are formed by singular spherical lapilli and bombs. These lapilli and bombs are the result of ... -
Partición de la deformación cenozoica intraplaca en el Sistema Central
(2009)A new model for Cenozoic strain partitioning is proposed here for the Central System at the Messejana (Plasencia) fault zone. It explains the simultaneous movement of parallel NE-SW trending thrust and strikeslip faults ... -
Mineralogía y génesis de gemas de corales silicificados de Sumatra
(2009)Mineral characteristics of silicified corals from Barisan Mountains (Miocene) of the Western Sumatra (Indonesia) have been studied by optical microscopy, Raman spectroscopy (spectral curves and hyperspectral images) and ... -
La sección de San Miguel de Salinas (Cuenca del Bajo Segura). Significado paleoambiental de las asociaciones de foraminíferos en relación con la Crisis de Salinidad del Messiniense
(2009)In the composite section of San Miguel de Salinas the following synthems are represented: MI (preevaporitic Messinan), MII (syn-evaporitic Messinian) and P (post-evaporitic Pliocene). The foraminiferal assemblages of ... -
Reconstrucción paleoclimática del centro de la Península Ibérica durante los últimos 50 ka cal. BP, a partir de los datos físicos y geoquímicos del registro lacustre del mar de Fuentillejo (Campo de Calatrava, Ciudad Real)
(2009)Physical (magnetic susceptibility and gamma density measurements) and geochemical (TOC, Fe and Ti analysis) analysis were performed to characterize the sedimentary record in Fuentillejo maar-lake (Campo de Calatrava ... -
Prospección hidrogeológica en zonas áridas de baja permeabilidad (Tifariti, Sahara Occidental) con el método EM de inducción
(2009)The aim of this study is to evaluate electromagnetic induction methods to analyze low permeability rocks in desert areas, as a tool for groundwater surveying. We have focused the field work in large faults zones, previously ... -
La fábrica de las rocas miloníticas de la Zona de Cizalla de Los Llanos (Calzadilla de los Barros, Badajoz)
(2009)The Los Llanos Shear Zone bounds the Cabeza Gorda and Zafra units located in the Ossa-Morena Zone (SW Iberian Massif). Within the Cabeza Gorda unit two peridotitic massifs crop out, named Sierra Cabeza Gorda and Cerro ... -
La evolución Holocena de la Albufera de Valencia
(2009)The “Albufera de Valencia” is one of the lagoons of bigger extension in the Iberian Peninsula. It is placed in a sedimentary basin that embraces part of the coastal plain of Valencia province and that expands several ... -
Intertidal foraminifera in the Mira estuary, SW Portugal, and their use as sea-level proxies
(2009)Para evaluar la respuesta cuantitativa de los foraminíferos con en relación con los niveles maréales del estuario de Mira, se han desarrollado una serie de funciones de transferencia basadas en un matriz de datos compuesta ... -
Influencia de la petrografía en las propiedades petrofísicas y de durabilidad del Travertino Clásico. Valoración de su anisotropía
(2009)The influence of facies on the petrophysical properties and durability of the Classic Travertine is studied. This travertine is a light travertine quarried in Turkey, which is widely used in Spain as building stone and ... -
