Actividad tectónica cuaternaria en la Cuenca de Huércal-Overa (Almería, Sureste de España): deformaciones asociadas a la falla de Albox
(Sociedad Geológica de España, 2004)The main Quaternary tectonic ativity in the Huercal-Overa Basin is related to the Albox fault, which extends from Tijola in the Almanzora Corridor (SSW) to the eastern Huercal-Overa Basin (NNE). In this work an example of ... -
Asociaciones de facies en los fan deltas de las cuencas neógenas y cuaternarias de las Cordilleras Béticas Orientales
(Sociedad Geológica de España, 1989)Fan deltas occur in a wide range of tectonic and sedimentary settings which are likely to generate a varied mosaic of facies associations. Fan delta deposits provide a good geodynamic record of basins as illustrated by ... -
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 ... -
Caracterización de la sedimentación Lago Mare (Messiniense terminal) y de la transgresión del comienzo del Plioceno en la cuenca de Málaga (Cordillera Bética)
(2008)A stratigraphic unit deposited close to the Messinian-Pliocene boundary is newly discovered in the Malaga basin. This unit mainly consist of alluvial and lagoonal deposits. Paleontological and paleomagnetic data from ... -
Caracterización de los depósitos miocenos de la isla de Nueva Tabarca (Alicante) y su empleo como material de construcción en el patrimonio local
(Sociedad Geológica de España, 2014)The aims of the present work are: i) the description of the Miocene deposits cropping out in the Nueva Tabarca island; ii) the characterization of the use of these rocks in the local heritage; and iii) the analysis of ... -
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 de los depósitos ferromanganesíferos de Las Herrerías (SE Ibérico)
(Sociedad Geológica de España, 1993)Various types of ferromanganese deposits, of Upper Miocene age, form part of the Las Herrerías mineralization (Betic Cordillera, SE Spain): Oxidized beds, crusts, hydrothermal pipes and brecciatype structures, thin layers ... -
Caracterización morfo-estructural del borde occidental de Sierra de Gádor (Cordillera Bética)
(2006)An integrated geomorphic and structural study has been performed along the western border of Sierra de Gádor (Betic Cordillera, SE Spain). To do this, we have calculated some of the most reliable geomorphic indexes for ... -
Concreciones de arenisca como criterio de identificación y correlación estratigráfica de regresiones forzadas. Un ejemplo desde las areniscas cretácicas de la Formación Cerrajón (Zonas Externas de la Cordillera Bética)
(2010)Calcite-cemented concretions were studied from Lower Cretaceous forced-regressive shoreface sandstones (Cerrajón Fm, External Zones, Betic Cordillera). During early diagenetic, patchy calcite cement consolidates clean and ... -
Deformaciones recientes en el extremo nororiental de la Cuenca de Baza (Cordilleras Béticas)
(Sociedad Geológica de España, 1988)Neotectonic deformations are presents in two areas from the Baza Basin (Betic Cordillera): Cuevas del Campo area and the Orce-Galera-Huescar triangle. In this work we analyse the main movements from Upper Pleistocene to actuallity -
Diaclasas de tensión regionales en el Complejo Nevado-FiIábride y su relación con el contacto Alpujárride/Nevado-FiIábride (Sierra Nevada, Cordilleras Béticas)
(Sociedad Geológica de España, 1989)Nevado-Filábride rocks have been strained by a NW-SE principal set of systematic tension joints. The orientation of the least principal stress derived from the NevadoFilábride/Alpujárride contact fault gouge agree with the ... -
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 ... -
Diques de lamproítas a lo largo de la Falla de Socovos (Béticas orientales)
(2010)The Calasparra segment of the Socovos Fault shows a large number of lamproite outcrops, most of them being dikes emplaced along tension gashes and Riedel faults. Subsequently to the emplacement, some of the dikes were ... -
Edad de las formaciones travertínicas del flanco meridional de la Sierra de Mijas (provincia de Málaga, Cordilleras Béticas)
(Sociedad Geológica de España, 1988)Three masses of travertines located on the southern flank of the Sierra de Mijas (Betic Cordillera) have been dated by absolute dating methods: E.S.R. and Uranium Series (ThU). The results relates the age of travertines ... -
El levantamiento Tortoniense-Cuaternario de Sierra Nevada (Granada, España): Fenómenos de tectónica gravitatoria en su borde occidental
(Sociedad Geológica de España, 1999)The former Alpujarride nappes at the western margin of Sierra Nevada are strongly affected by gravitational collapse phenomena, with significant thinning of their original thickness, creation of new detachment surfaces and ... -
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 ... -
El prisma orogénico prebético
(Sociedad Geológica de España, 1996)The frontal part of the Prebetic zone corresponds to an orogenic prism (accretionary wedge) which obeys the critical taper model. Three sections parallel to the transport direction show conspicuous similarities with the ... -
El Trías Betibérico. Una nueva interpretación sobre el Triásico basada en unidades tectosedimentarias
(Sociedad Geológica de España, 1996)By means of a field work, carried out in the Eastern Spain Triassic outcrops, (mainly Muschelkalk and Keüper), within the area extended between Cuenca and Murcia parallels> toghether with other observations in the external ... -
Esfuerzos recientes en el sector sudoriental de la Depresión de Granada (Cordillera Bética central)
(Sociedad Geológica de España, 1997)The analysis of the seismic activity and the microtectonic study of outcrops located in the southeastern Granada Depression show that the stress states have been heterogeneous from the Upper Miocene up to the present. NE-SW ... -
