El Valanginiense superior de la sección de Oliva (Zona Prebética, Valencia): análisis de facies, bioestratigrafía, isótopos de carbono y geoquímica orgánica
(Sociedad Geológica de España, 2014)The Upper Valanginian stratigraphic section of the sierra de la Oliva (Prebetic, Valencia province) records a significant sedimentary episode which has been named as ”Weissert Event”.This event is characterized by a ... -
Sedimentología y cicloestratigrafía de la Formación Barahona (Jurásico Inferior) en la Rama Aragonesa de la Cordillera Ibérica
(Sociedad Geológica de España, 2014)A detailed bed-by-bed sedimentological and cyclostratigraphic characterization of the Barahona Formation has been carried out in two representative outcrops in the Aragonese Branch of the Iberian Range, in order to ... -
Análisis de anomalías gravimétricas y modelación cortical 2D de la región volcánica del Campo de Calatrava (Ciudad Real, España)
(Sociedad Geológica de España, 2014)The volcanic region of Campo de Calatrava has been interpreted as a process of intraplate volcanism developed during Neogene. Two opposed geodynamic models have been proposed to explain the origin of this volcanism: a) ... -
Geological interpretation of aeromagnetic data from Bou Chber area, Central Moroccan Massif
(Sociedad Geológica de España, 2014)This study concerns the geological interpretation of aeromagnetic data of Bou Chber region located in Central Morocco. Processed magnetic maps obtained through different standard methods known in aeromagntism were compared ... -
Complex strain partitioning patterns evaluated via triclinic transpression models. Kinematic analysis of the Valle de Abdalajís massif (Torcal shear zone, External Betics)
Díaz Azpiroz, Manuel; Barcos, Leticia; Expósito, Inmaculada; Jiménez Bonilla, Alejandro; Balanyá, Juan Carlos; Fernández Rodríguez, Carlos
(Sociedad Geológica de España, 2014)
Complex strain partitioning patterns are very common in the continental crust. They are often related to the kinematics of three-dimensional deformations and hence, can be analysed using transpression models. In this work, ... -
Reparto de la deformación en la terminación oriental de la Zona de Cizalla del Torcal (Béticas, S España)
(Sociedad Geológica de España, 2014)The eastern end of the Torcal Shear Zone (TSZ) is made up of two structural domains that accommodate variable proportions of the strain partitioning associated to the TSZ dextral transpressive deformation. The Sierra ... -
Subsidence and uplift during the Plio-Quaternary in the Oued Laou and Tirinesse sectors (Internal Rif, Morocco)
(Sociedad Geológica de España, 2014)The Oued Laou area and the Tirinesse basin are filled with early Pliocene (Zanclean) marine sediments very slightly deformed but currently outcropping at different altitudes. In Tirinesse area Zanclean sediments reach ... -
The early Pliocene Tirinesse basin (SW of Oued Laou, Rif, Morocco): proposal of a formation model
(Sociedad Geológica de España, 2014)The Tirinesse basin, filled mainly by lower Pliocene marine sediments, is a small tectonic graben bounded by two NE-SW normal faults, with the eastern one surpassing 500 m in throw. These faults proved to belong to a ... -
Folding and fracturing relationships from Jurassic limestones of South Rifian Ridges, Northern Morocco
(Sociedad Geológica de España, 2014)The study of fractures affecting the Jurassic Ridges of Fert El Bir, Kefs and Outita from South Rifian Ridges, Northern Morocco, allowed us to propose a folding-fracturing model that summarizes the distribution of fractures ... -
Resultados preliminares sobre la aplicación de la técnica de racemización de aminoácidos en la Región de Murcia (SE de la Península Ibérica) y su interés en estudios de paleosismología
(Sociedad Geológica de España, 2014)Geochronology is a critical issue in paleoseismological research. The aminoacid racemization technique shows important advantages respect to more traditional dating methods; not just for the lower costs and promptness, also ... -
Análisis de los esfuerzos tectónicos de la crisis sísmica de 2010 en Haití
(Sociedad Geológica de España, 2014)The Mw=7 event of the January 12th, 2010 triggered a seismic crisis in the southern Haiti that continued for 3 months. The epicenter was located in an E-W oriented transpressive plate boundary where E-W trending ... -
Aproximación a la peligrosidad sísmica en la ciudad de Teruel asociada a la falla de Concud (NE España)
(Sociedad Geológica de España, 2014)This paper presents the results ofa probabilistic seismic hazard analysis at Teruel city from seismological and geological information. The characteristic earthquake of the Concud fault (M ~ 6.8; recurrence period = 7.3 ... -
Tasas de deformación GPS en la cuenca del Bajo Segura (Cordillera Bética oriental)
(Sociedad Geológica de España, 2014)We estimate the present deformation rates ofthe Bajo Segura Basin (NE end of the Eastern Betic shear zone), from the analysis of a GPS network with 11 sites. We analyze the data from four observation campaigns carried out ...
