Análisis de la fábrica magnética en el Sinclinorio de Bizkaia: Implicaciones en la tectónica regional
(Sociedad Geológica de España, 2017)A combined structural and AMS analysis is made in Upper Cretaceous rocks from the periclinal closure of the Biscay Synclinorium (Basque-Cantabrian basin). Fieldwork has led to the recognition of a broad band with a pervasive ... -
Application of specific extraction chromatographic methods to the Rb-Sr, Sm-Nd isotope study of geological samples: The Hombreiro-Santa Eulalia Granite (Lugo, NW Spain)
(Sociedad Geológica de España, 1996)The analytical application to geological samples of three new chromatographic resins, TRU-Spec ®, Sr-Spec ® and LN-Spec ®) has been investigated. Seven samples of the Hombreiro massif (Lugo, NW Spain) have been studied, ... -

(Sociedad Geológica de España, 1997)This paper is a brief description of the Hercynian calc-alkaline granodioritic pluton of the Los Pedroches batholith at its NW branch (La Serena, Badajoz). This study is located in the National Topographic Map N.T.M. number ... -
Caracterización mineralógica y química de la granodiorita de Los Pedroches en la zona de cizalla dúctil de Conquista
(Sociedad Geológica de España, 2001)The northern edge of Los Pedroches granodioritic pluton is deformed by the Conquista fault, a right ductile shear zone with a normal component. Consecuently, the rocks of this sector show gradual texture-structural ... -
Control estructural del Batolito de Tastil (Salta, Argentina) en el desarrollo de cabalgamientos andinos
(2006)This work deals with the structure of the Lower Cambrian batholith of Tastil (Salta, NW Argentina) and its influence on the development of younger Andean structures. Anisotropy of magnetic susceptibility data reveal a ... -
El granitoide de Manzaneda, marcador del acortamiento NE-SW en el arco hercínico
(Sociedad Geológica de España, 1997)The Manzaneda granite (NW Spain) is located at the southern sector of the Calida Variscan arc. It shows a NW-SE elongated shape, and covers ah area of about 400 Km2, within thè «P/ló de Sapo» anticlinorium. It is a ... -
Estructura del plutón de La Paya (Sierra de Cachi, Argentina)
(Sociedad Geológica de España, 2015)El granito de La Paya se localiza en la Sierra de Cachi (Salta,Argentina), que pertenece a la Cordillera Oriental de Los Andes. Los nuevos datos estructurales y cartográficos disponibles, combinados con el estudio de ... -
Estructura del pluton sincinematico de Lys (Zona Axial del Pirineo)
(Sociedad Geológica de España, 2003)From the structural study (using field, microstructural and anisotropy of magnetic susceptibility data) of the central traverse across the Lys pluton (Pyrenean Axial Zone), w'e propose that the emplacement of this pluton ... -
Estructura geológica en el borde oriental del Anticlinorio de Bilbao
(Sociedad Geológica de España, 1989)This paper provides new structural data from the Bilbao Anticlinorium, near Santurce (Basque Country). Lower Cretaceous rocks within this region show bed-parallel-thrusts, which are deformed during the development of the ... -
Estructura magnética de los macizos graníticos de Guitiriz y Hombreiro-Santa Eulalia de Pena (Lugo)
(Sociedad Geológica de España, 1991)The magnetic susceptibility anisotropy of 202 sites from the Variscan Guitiriz and HombreiroSanta Eulalia granites (Galicia, Spain) has been measured. The magnetic fabric is directly related to the field structures. The ... -
Estructuras sigmoïdes en el macizo granítico hercínico de Cauterets-Panticosa (Pirineos)
(Sociedad Geológica de España, 1996)The emplacement of the Cauterets-Panticosa granite massif (western Pyrenees) was controlled by dextral, 100° E-trending shear zones. The anisotropy of magnetic susceptibility allows us to obtain detailed structural maps ... -
Estudio de la fábrica magnética (ASM) y modelo de emplazamiento del macizo granítico de Trives (Galicia)
(Sociedad Geológica de España, 1997)The Trives granodiorite (NW Spain) is located within the metasediments of the «Olio de Sapo» antiform (northern part of the Iberian Variscan belt). The zonation of bulk low-field susceptibility indicates a more basic ... -
Estudio de las fábricas magnéticas y del magnetismo de las rocas en los plutones de Sotillo y Ribadelago (Sanabria, Zamora)
(Sociedad Geológica de España, 2003)Magnetic fabric and rock magnetism studies were performed in 14 samples of the Ribadelago and Sotillo plutons (Iberian Variscan belt, NW Spain). These heterogeneous granitoids are composed by granodiorites, tonalités, ... -
Fabrica magnética y emplazamiento del plutón Alpa Corral (Sierras de Córdoba, Argentina)
(Sociedad Geológica de España, 2003)Nearly circular in outcrop, the Alpa Corral plutón is one of the post-tectonic monzogranitic plutons of the Sierras Pampeanas, in Córdoba (Argentina). This pluton intrudes the Early Paleozoic basement of the Sierras Pampeanas ... -
Implicaciones geológicas de la presencia de mármoles con escapolita en el Sinclinorio de Vizcaya
(Sociedad Geológica de España, 1997)We report by the first time the finding of scapolite-bearing marbles in the Southern limb of the Biscay Synclinorium (Basque-Cantabrian basin). Marbles are found as layers or fragments in Triassic evaporites. I. Evaporitic ... -
Los plutones de Sotillo y Ribadelago, (Sanabria, Zamora) ejemplos de intrusiones laminares en la zona de relevo de una zona de cizalla dextra transpresiva
(Sociedad Geológica de España, 2001)The Ribadelago and Sotillo plutons are located in the Central Iberian Zone, a tectonic domain of the Iberian Variscan belt (NW Spain). These synkinematic granitoids are composed by swarms of sheeted intrusions parallel to ... -
Nuevos datos geocronologicos Rb - Sr del pluton de Campanario - La Haba (batolito de Los Pedroches, Extremadura)
(Sociedad Geológica de España, 2003)A Rb-Sr whole-rock array corresponding to a circa age of304 ± 6 Ma has been obtained for the peraluminous granite of Campanario - La Haba pluton. The Sr initial ratio of 0.70619 ± 0.00034 of this pluton is less radiogenic ... -
