Cicliciclad en carbonatas lacustres paleógenos: Formación Morera del Montsant, Tarragona
(Sociedad Geológica de España, 1994)The Formation La Morera del Montsant Limestones (medium-upper Lutetian) is constituted by different sort of mudstones deposited in lacustrine and palustrine environment.The different facies associations allow us to obtain ... -
Controles alocíclicos en el relleno sedimentario de una cuenca Paleógena: arquitectura deposicional del Grupo Cornudella, Cuenca del Ebro (Tarragona)
(Sociedad Geológica de España, 1994)The non-marine Cornudella Group (Thanetian-Bartonian) is constituted by different lithostratigraphic units. La Morera Formation is characterized by mudstones deposited in lacustrine and palustrine environments. The Ulldemolins ... -
Costras carbonatadas en la sucesión aluvial distal eocena de la Formación Hamada de Boudenib II al sur del Alto Atlas (Marruecos)
(Sociedad Geológica de España, 2003)On the southern edge of the High Atlas Mountains of Morocco, the Tertiary continental deposits form extensive tablelands, the so-called "Hamada", in the Boudenib area. Two units have been defined in' the Paleogene: a Lower ... -
Estratigrafía del llerdiense en la región de Tremp (cuenca de Graus-Tremp, NE de España)
Barberà, X.; Marzo, M.; Reguant, Salvador; Serra Kiel, Josep; Samsó, Josep Maria; Tosquella Angrill, Josep
(Sociedad Geológica de España, 1996)
A new stratigraphic subdivision of the Herdian stratotype in the Tremp basin is proposed. The Figols Croup has been defined as a new unit which comprises a succession of shallow marine sediments about 750 m thick. This ... -
Estructura del sector norte de la Cuenca de Almazán (Cordillera Ibérica)
(Sociedad Geológica de España, 1997)The Tertiary compressional structure of the northern sector of the Almazan basin is defined by several E-W to NW-SE trending folds. These folds extend from the northern and eastern basin borders to the central part. ... -
Estructuras contractivas de la Cordillera Prelitoral Catalana entre la sierra de Les Pedritxes y el río Ripofll: evolución y relación con los depósitos del márgen de la cuenca del Ebro
(Sociedad Geológica de España, 1994)During paleogene times the deformation area associated to the Vallés fault system developed a series of compressive structures. In itially there was theem placement of a succession of thrusts and folds affecting mainly the ... -
Evolución del sistema deposicional paleógeno de Rosseil (Baix Maestrat, Castellón)
(Sociedad Geológica de España, 1996)The study of facies associations allows us to distinguish three informal lithostratigraphic units: in the stratigraphic type section of the Rossell paleogene, Rossell-I limestones which represents the upper Paleocene, ... -
Fossil associations from the middle and upper Eocene strata of the Pamplona Basin and surrounding areas (Navarre, western Pyrenees)
Astibia, H.; Tosquella Angrill, Josep (Universidad Complutense de Madrid, 2016)
Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral ... -
Geometría y distribución de facies en la cuenca paleógena de Zamora. Datos derivados de sondeos
(Sociedad Geológica de España, 2003)The main goal of this paper is the study of the geometry and distribution of the units that made up the infilling of the southwestern basin margin. The drilling analysis and geological cross section define an eastern-western ... -
Hallazgo de un fósil silúrico en los depósitos auríferos cenozoicos de la mina romana de Las Médulas (León, NO de España)
(2006)A Silurian fossil has been collected from sandstone pebbles in the red Cenozoic deposits of the famous Roman gold-mine of Las Médulas. It consists on an articulated shell of the cardiolid bivalve Cardiola gibbosa Barrande, ... -
Ignimbritas paleógenas en Mallorca (islas Baleares)
(Sociedad Geológica de España, 1987)An ignimbritic sheet interlayered in Paleogene (Oligo-Miocene?) continental deposits in the Northern Ranges of Majorca is made up of rhyolites and K-rich rhyolites, of presumed calc-alkaline origin. This volcanic activity ... -
El Ilerdiense de la Serra D`Aubens. Correlacion con la Vall d`Ager
(Sociedad Geológica de España, 1991)The Paleogene deposits in the Serra d'Aubens (Segre valley) provide the eastermost outcrop of the assymetrical Ager sincline. Based on sedimentological and biostratigraphic analyses, four Ilerdian depositional sequences ... -
