Caracterización geológica para el emplazamiento de instalaciones de riesgo
(Sociedad Geológica de España, 1996)Certain installations are devoted to risky activities such as nuclear facilities (power plants, waste repositories), sanitary landfills or some chemical industries. Placing such plants into the land, deserve specific ... -
Caracterización geoquímica de partículas sedimentarias en una población urbana e industrial: el caso de Puertollano (Ciudad Real)
(Sociedad Geológica de España, 1996)This study concerns the geochemical characteristics of deposited particles in an urban area -namely the urban area of the mining and industrial city of Puerto llano. This falls with in the context of environmental systems, ... -
Contribución de los magmatismos presentes en la Comunidad Autónoma de Aragón al Patrimonio Geológico
(Sociedad Geológica de España, 1996)The main features (composition, age and setting mode) for eight igneous units outcropping in the Aragon Autonomus Community are exposed in this paper, justifying their inclusion within the Geological Heritage. These units ... -
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 ... -
Deterioro selectivo de la piedra de construcción de la catedral de Palma de Mallorca
(Sociedad Geológica de España, 1996)Palma de Mallorca cathedral (Spain) is built with four types of carbonate rocks (one limestone, one dolomitic limestone and two dolomites). The forms and degree of degradation of these stones depend on their petrophysical ... -
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 ... -
Digitalización de Imágenes aplicada a material cerámico. Caso práctico de caracterización de las producciones de un horno musulmán de Zaragoza
(Sociedad Geológica de España, 1996)Digital image analysis is becoming an important tool in many areas of Mineralogy and Petrology. The application of this technique to characterise the texture and fabric of ancient pottery and to discriminate between ... -

Dabrio, Cristino José; Borja Barrera, Francisco
; Zazo, C.; Boersma, J. R.; Lario, J.; Goy, José L.; Polo, María Dolores (Sociedad Geológica de España, 1996)
Facies analysis and tridimensional relationships of the eolian and eolian-connected deposits of Pleistocene and Holocene age in Huelva allow to propose sedimentary models and discuss their temporal evolution and chronology -
El magmatismo calco-alcalino, pérmico, de la cadena Ibérica: su interés como Patrimonio Geológico
(Sociedad Geológica de España, 1996)Some criteria are here exposed (petrology, tectonics, stratigraphy and fosil data) in order to include some representative outcrops of the Permian calk-alcaline magmatism (SW, Iberian Range) within the Geological Heritage -
El magmatismo Toleítico, Trías-Lías, de la cadena pirenaica: afloramiento con interés en el Patrimonio Geológico
(Sociedad Geológica de España, 1996)In this paper, a selection o f the most important features of Triassic tholeiitic dolerites in the Pyrenean domain, and the description of the best outcrops of this magmatism are exposed. The inclusion o f these outcrops ... -
El mapa geológico de Cataluña a escala 1:25.000
(Sociedad Geológica de España, 1996)The sheets of the “Mapa Geoldgic de Catalunya 1:25.000" are conceived as selfsufficient documents. Thus, full information for the correct interpretation of the geological data must be included in the sheet. The elements ... -
El paleomagnetismo como indicador de paleotemperaturas. Aplicación a las Cordilleras Béticas
(Sociedad Geológica de España, 1996)Previous palaeomagnetic studies performed in the Western Internal Subbetics revealed the presence of a widespread neogene remagnetization in these units. In this work we analyze the hypothesis of a thermoviscous remagnetization ... -
