Correcciones geométricas en magnetotectónica: Filtrado de rotaciones aparentes debidas a pliegues
(Sociedad Geológica de España, 1996)The evaluation of apparent rotations asociated with different geological structures is an important task that has to be taken into account to correctly interprete paleomagnetic data. In this paper, the way to calculate ... -
Datación magnetoestratigráfica de la cuenca terciaria de As Pontes (Galicia, NW de España)
(Sociedad Geológica de España, 1996)The Tertiary Basin of As Pontes (Northwest Spain) has been dated by means of magnetostratigraphy. A total of four local magnetostratigraphic successions have been constructed. In the four succesions 500 sites were sampled ... -
Datos magnetotectónicos del Eoceno de la Cuenca de Jaca-Pamplona: resultados iniciales
(Sociedad Geológica de España, 1996)This paper presents the first magnetotectonic data of the central fringe of the Jaca-Pamplona Basin. These data have been obtained from 16 sites located in marls, tirbidites and limestones of Eocene age. In the central and ... -
Deformación contractiva del margen noroeste ibérico: Implicaciones tectónicas del estudio paleomagnético de la Cuenca de As Pontes (NW España)
(Sociedad Geológica de España, 1996)The magnetochronology of the syntectonic sedimentary infilling of the Tertiary Basin of As Pontes (Northwest Spain) has allowed to determine that the activity of the N W -SE dextral strike -slip faults systems o f Galicia ... -
Determinación de fábricas mediante la anisotropía de la susceptibilidad magnética (ASM) en rocas con diferente grado de deformación. Ejemplo de materiales eocenos de la cuenca de Ainsa (Pirineo Central)
(Sociedad Geológica de España, 1992)The anisotropy of magnetic susceptibility (AMS) has been used to establish the petrofabric of some Eocene grey marls from the southern Pyrenees. The rocks are affected by increasing deformation conditions fron wakly to ... -
Determinación del polo paleomagnético para el límite Oligoceno-Mioceno en la Cuenca del Ebro
(Sociedad Geológica de España, 1996)A paleomagnetic study was carried out in Oligocene-Miocene fluvial and lacustrine sediments of the Ebro Basin. A significative number of samples are treated. A Paleomagnetic Pole for the Oligocene-Miocene boundary in the ... -
Estado actual de las investigaciones paleomagnéticas en la cuenca de Guadix-Baza (Cordilleras Béticas)
(Sociedad Geológica de España, 1997)This report provides a record of contributions of paleomagnetic research in the Plio-Pleistocene deposits from Guadix-Baza Basin. It is intended to be a working reference for researchers -
Fábrica magnética en las limolitas wealdenses del borde oriental de la Cuenca de Cameros (Cordillera Ibérica): correlación con la deformación finita
(Sociedad Geológica de España, 1996)The Anisotropy of Magnetic Susceptibility (AMS) of some wealdian siltstones outcroping in the eastern border of the Sierra de Cameros (NW Iberian Chain) has been analyzed in order to stablish its correlation with strain. ... -
Magnetocronología del Plioceno superior continental de la cuenca de Guadix-Baza (Cordilleras Béticas)
(Sociedad Geológica de España, 1996)Stratigraphic superposition of mammal fossil-rich localities makes the Galera section (Baza Fm, Guadix-Baza Basin, Betics) very appropriate for magnetostratigraphic dating of the Late Pliocene continental biochronology. ... -
Magnetoestratigrafía del Triásico medio de la Cadena Costero Catalana. Resultados iniciales
(Sociedad Geológica de España, 1992)A magnetostratigraphic reconnaissance of the Middle Muschelkalk red beds from the Catalan Coastal Range is presented. The selected section is composed by red mudstones and sandstones 25 mt thick. Although the sedimentay ... -
Magnetoestratigrafía preliminar de los materiales pliocenos de la Cubeta de Villarroya. (Sierra de Cameros, La Rioja)
(Sociedad Geológica de España, 1996)In this work we report a magnetostratigraphic study of a Pliocene section at Villarroya basin. The correlation with the Geomagnetic Polarity Time Scale (GPTS) is tied by the existence of a well-defined paleontological ... -
Migraciones intercontinentales y eustasia: el datum de Hipparion
(Sociedad Geológica de España, 1996)The magnetostràtigraphic study of vallesian sites in the Vallès-Penedès Basin (NE Spain) provides a reliable dating of the earliest appearance of Hipparion at 11.1 Ma. Good agreement with radiometric ages from other sites ... -
Puntos de interés geológico en un espacio periurbano (Badalona). Una herramienta para la enseñanza de la geología
(Sociedad Geológica de España, 1996)In order to improve the geological maps o f the Badalona area o f Barcelona, a geological scheme o f the area was generated by the GIS program which was used to digitize information from orthomaps. Ground truth was provided ... -
La utilización de la anisotropía de la susceptibilidad magnética (ASM) en el estudio de la deformación finita: ejemplo en la zona milonítica de Cap de Creus (Catalunya)
(Sociedad Geológica de España, 1988)The magnetic susceptibility anisotropy (MSA) of the Roses Granodiorite has been studied The magnetic fabric is due to the shear zones that affect these rocks. In this sense, the kmin axes of the MSA are paralel to the ...
