(2009)The Villar del Arzobispo Formation (Tithonian-Berriasian) in Teruel and Valencia provinces (SE Iberian Range) has yielded abundant skeletal remains of dinosaurs, mainly of sauropods and stegosaurs. Three vertebrae collected ... -
Unidades Preordovícicas y Megaestructuras Cadomienses en La Serena y La Siberia Extremeña (Macizo Ibérico meridional)
(2009)New mapping of the pre-Ordovician basement (Schist and Greywacke Complex or Lower Alcudian) from the La Serena and La Siberia Extremeña regions of the southern Central Iberian zone has allowed the distinction of up to ... -
Etapas de formación de dolomías masivas del entorno de La Florida-El Soplao, Cantabria
(2009)Dolomitization played a very important role in producing porosity within the Late Aptian shallow marine carbonates hosting the El Soplao Cave and La Forida mine deposit. A detailed petrographic study of samples from a ... -
Estudio morfométrico comparativo de la escápula y húmero de ciervo (Cervus elaphus) y reno (Rangifer tarandus) del Pleistoceno Superior
(2009)The aim of this paper is to offer a comparative morphometric study of scapula and humerus between red deer (Cervus elaphus) and reindeer (Rangifer tarandus). Both species show a similar morphology but with small differences ... -
Cefalópodos del Ordovícico Medio de la Formación Valongo, norte de Portugal
(2009)Ordovician cephalopods from the Valongo Formation are among the first Ordovician fossils described from the Iberian Peninsula. The present review shows a lower taxonomical diversity than previously reported. Large ... -
Basaltos subalcalinos en las coladas de la cuenca del Ser (Zona Volcánica de Olot)
(2009)The geochemical study of pyroclastic cones and flows of the Ser basin (Olot Volcanic Field, NE Spain) shows significant compositional differences among the volcanic centers and flows. The seven cones sampled are typically ... -
Pistas fósiles asociadas a la discontinuidad fini-Messiniense en el margen norte de la Cuenca del Bajo Segura (SE España)
(2009)A detailed analysis of the Upper Messinian-Lower Pliocene at the northern border of the Bajo Segura Basin (BSB) has been carried out. Trace fossils of firm- and rockground were collected, aiding in the recognition of ... -
Indicadores geoquímicos de cambios ambientales en secuencias aluviales holocenas de Bardenas Reales
(2009)Geochemical features and Chemical Index of Alteration (CIA), corrected for Ca from calcite, were studied in Holocene alluvial sequences from Bardenas Reales of Navarra. The five sequences, distinguished by using ... -
Anisotropía de la Susceptibilidad Magnética y direcciones de flujo en diques recientes. Complejos volcánicos de las Islas Corvo y Flores (Azores Occidentales, Placa Norteamericana)
(2009)Different models of relation between flow and Anisotropy of Magnetic Susceptibility axis have been postulated. The main models link the magnetic foliation with the dyke wall, where the magnetic lineation is parallel to ... -
Edad y significado de las tufas sobre el río Dúrcal en Cónchar (Granada, Andalucía, España)
(2009)The ages of the tufa terraces of the Dúrcal River, in the vicinity of Cónchar, were obtained through the amino acid racemization method, which define the begining of the fluvial incision and the successive periods of ... -
Juan Vilanova y Piera (1821-1893) y la primera tortuga hallada en el Mesozoico español
(2009)MNCN 59511 is a natural inner cast of the caparace of a Pancryptodiran turtle from the Lower Cretaceous of Morella (Castellón), whose discovery was attributed to José Royo y Gómez. However, information available at the ... -
Turbiditas carbonatadas en la Playa de Muriola (Barrika, Arco Vasco): edad, deformación, contenidos de CaCO3 y presencia de barita diagenética
(2009)The Playa de Muriola sea-cliff exposes three different sections of carbonate turbidite layers from the Early Turonian of the deep Basque Arc domain. High-resolution analysis (% CaCO3) of the turbidites (calcarenites and ... -
Relaciones entre tectónica y sedimentación asociadas a las Rides Prérifaines en la Cuenca de Volubilis (frente del Rif, Marruecos)
(2009)The Volubilis Neogene basin (Morocco) was part of the South Rif Corridor that connected the Atlantic Ocean with the Mediterranean. This basin recorded the tectonic - sedimentary interactions of a foreland basin subjected ... -
Jade nefrítico en las peridotitas de Ronda
(2009)We report the presence of nephrite jade, a semiprecious gemstone, in the Ronda peridotites (Betic Cordilleras, southern Spain). These rocks are formed by submicroscopic to fine-grained aggregates of tremolite with felted ... -
Caracterización química de esfenas ígneas y aplicación del geotermómetro de Zr en esfena a procesos tardimagmáticos
(2009)This preliminary work illustrates the chemical composition of sphene from Variscan tonalites with sphene-centered ocellar texture (Ribadelago pluton, NW Iberian Massif). The ocellar texture is linked with the percolation ... -
