Resultados preliminares en la caracterización geométrica 3D de un litosoma arenoso de progradación deltaica mediante georadar (GPR) (Fm. Arenisca de Roda, Eoceno, Cuenca de Graus-Tremp)
(2006)A set of GPR profiles have been recorded in order to determine the 3D geometry of a prograding delta-front sandbody (Roda sandstone formation, Eocene, Graus-Tremp basin). Common Mid Points (CMP) also have been recorded ... -
Respuesta mecánica de medios bifásicos. Influencia de la disposición espacial de sus constituyentes
(2006)Numerical simulations were per formed to investigate the strain-dependent behaviour of rheological response to flow of two-phase rocks. Two types of microstructures were considered: strong phase supported (SPS) and weak ... -
Relación entre composición de areniscas y procedencia. Casos de estudio en areniscas paleozoicas de la Zona Surportuguesa
Two different types of Upper Paleozoic sandstones from Southportuguese Zone are studied. Data coming from petrographic, sedimentological and regional analyses of the sandstones point to two different anomalies in relation ... -

(2006)In this paper the faunistic sample, the stratigraphy and the chronology of the archaeological site of Kobeaga II cave (Ispaster, Bizkaia) is described. The five Classes of vertebrates are represented in this site, where, the ... -
Validez e interpretación de los datos geotermométricos de los esquistos cloríticos con circón en las peridotitas de Ronda (Cordilleras Béticas)
(2006)This work reports the most precise geochemical compositions and geothermometric calculations of zirconbearing chlorite schists located at the south-western part of the Sierra Bermeja peridotite massif. The combination ... -
U-Pb dating of Siluro-Ordovician volcanism in the Verín Synform (Orense; Schistose Domain, Galicia-Trás-os-Montes Zone)
(2006)El Grupo Paraño constituye la parte más alta de la estratigrafía del Dominio Esquistoso de Galicia-Trásos- Montes y está expuesto en el núcleo de la Sinforma de Verín. Como al resto del dominio, a este grupo se le ha ... -
Tectonic and Stratigraphic Description and Mapping of the Santa Susana Shear Zone (SSSZ), the SW Border of Ossa Morena Zone (OMZ), Barrancão – Ribeira de S. Cristóvão Sector (Portugal): Theoretical Implications
(2006)Se ha realizado una cartografía de la Cuenca de Santa Susana (Vestfalialiense D – Estefaniense A), situada en el limite SW de la ZOM con la Zona Sur Por tuguesa (ZSP). Esta región se caracterizada por una frontera tectónica ... -
Some misleading boudin-like structures
(2006)Las estructuras de boudinage son indicadoras de extensión paralela a las capas. Sin embargo, existen estructuras que poseen un alto grado de similitud con los boudins pero cuyo origen no está relacionado con un estiramiento ... -
Química de las aguas de goteo en la Cueva de Canelobre (Alicante)
(2006)The Cave of Canalobre, located in the west middle of the Alicante province, is one of the most visited cave in Comunidad Valenciana. During the last years some drip water samples have been collected. The analytical results ... -
Pulsos de inundación marina en la terminación de una plataforma carbonatada (Aptiense inferior de Aralar, Cuenca Vasco-Cantábrica)
(2006)The Lower Aptian Sarastarri Limestone unit (Aralar, nor thern Spain), mainly consists of rudist and coral micrites and is nearly 200m thick. The uppermost 30m of the unit show sharp-based marly intervals attributed to ... -
Procedencia de los conglomerados sinorogénicos de La Pobla de Segur, Pirineos centro-meridionales
(2006)Clast composition of conglomerates in sedimentary record has been broadly used in palaeogeographic and palaeotectonic reconstruction, as they reflect the litology of the source area. Moreover, in sintectonic sediments, ... -
Presencia de la icnoespecie Dactyloidites ottoi en el complejo de abanico costero de Sant Llorenç del Munt (Eoceno, Cuenca del Ebro, NE de España)
(2006)The presence of Dactyloidites ottoi is first recorded in the Eocene Sant Llorenç del Munt fan-delta complex. This constitutes the first citation for the Paleogene. The ichnospecies occurs in the lower part of a ... -
