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 ... -
Can the zircon origin be established from geochemical data alone? Insights from chlorite schists in the Ronda peridotites
(Sociedad Geológica de España, 2020)This study deals with the scarce chlorite schists scattered through the Ronda peridotites (Betic Cordilleras, Spain) related to the intrusion of granite dykes. Chlorite schists field data and the petrography, geochemistry ... -
Características petrográficas y mineralógicas de birbiritas derivadas de las peridotitas de Ronda (Cordilleras Béticas)
(Sociedad Geológica de España, 2011)Por primera vez en las Cordilleras Béticas describimos, en este trabajo, la existencia y las principales características mineralógicas y petrológicas de birbiritas que son el resultado de un intenso metasomatismo de ... -
Caracterización geoquímica de las peridotitas del macizo de Sierra de Aguas (Málaga)
(Sociedad Geológica de España, 2004)In order to constraint geochemical differences related to the petrogenesis ofthe Ronda peridotites, major and trace elements combined with chondrite normalized REE patterns of the Sierra de Aguas Massif peridotites, near ... -
Caracterización geoquímica y encuadre geodinámico de las anfibolitas y eclogitas del manto de Ojén, Complejo Alpujárride, Cordilleras Béticas
(Sociedad Geológica de España, 2009)Amphibolite bodies with eclogite relics are found interlayered between the Ojen nappe´s crustal rocks, below the Ronda peridotites of the Betic Cordilleras (southern Spain). We present a geochemical study of such ... -
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 ... -
Caracterización química de esfenas ígneas y aplicación del geotermómetro de Zr en esfena a procesos tardimagmáticos
(2009)This preliminary work illustrates the chemical composition of sphene from Variscan tonalites with sphene-centered ocellar texture (Ribadelago pluton, NW Iberian Massif). The ocellar texture is linked with the percolation ... -
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 ... -
Determinación de la naturaleza de la falla de Cerro Tajo (Macizo peridotítico de Carratraca) mediante termocronología de trazas de fisión
(Sociedad Geológica de España, 2004)Fission-track thermochronology has been applied to assess the nature of the tectonic contact of Cerro Tajo, near Carratraca (Málaga). Zircon fission-track ages support the idea of the extensional nature of the Cerro Tajo ... -
Diapirismo del manto inducido por delaminación en las peridotitas de Ronda (Cordilleras Béticas)
(Sociedad Geológica de España, 2004)The contribution of asthenosphere diapirs to the exhumation of Orogenic Lherzolites from the mantle to the Earth’s surface stands as a major issue in the evolution of orogenic belts. Structural and textural data from the ... -
Distribución de la deformación en granitoides sincinemáticos intruidos en condiciones transpresivas (Sanabria, Zona Centro-Ibérica, Macizo Ibérico)
(2007)The Sanabria Lake plutons, located in the Central Iberian Zone of the Iberian Massif, intruded in a dextral strike-slip fault bridge under transpressive conditions. The deformed zone underwent a strain partitioning process, ... -
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 complejo alcalino de Rangel (Salta, Argentina)
(2008)This work deals with the structure and emplacement of the alkaline complex of the Sierra de Rangel, a Cretaceous stock intruding in Ordovician metamorphic rocks of the Puna region at Salta, northwest Argentina. Field ... -
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 ... -
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, ... -
