(Sociedad Geológica de España, 2014)Early Jurassic brachiopods from several localities in North and Northeast Spain housed in the Jiménez de Cisneros historical collection have been updated.These specimens have been referred to nowadays widely recognized ... -
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 ... -
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 ... -

Nuevo hallazgo de restos de proboscídeo en depósitos fluviales afectados por procesos kársticos. Pleistoceno inferior de la Cuenca del Ebro, Zuera (Zaragoza)
(Sociedad Geológica de España, 2014)A partial tusk of Elephantidae indet. was recently discovered in Early Pleistocene gravel deposits belonging to a terrace of the Gállego River, near to Zuera village. Stratigraphic studies have allowed four sedimentary ... -
Primeros resultados de monitorización de la Cueva de El Recuenco (Ejulve, Teruel)
(Sociedad Geológica de España, 2014)El Recuenco Cave (Ejulve, Teruel, NE Spain) is developed with a complex topography in Upper Cretaceous dolomitic limestones. A monitoring survey is in progress in the cave (covering now the 1st semester of 2013) in ... -
Identificación de varios taxones de quelonios en el Vallesiense (Mioceno superior) de Arévalo (Ávila, Cuenca del Duero, España)
(Sociedad Geológica de España, 2014)In this paper we identified the presence of two taxa of turtles so far not mentioned in the known paleontological area of Arévalo (Ávila). This region was known from the first half of the twentieth century by its findings ... -
Estratigrafía y quimioestratigrafía del Valanginiense (pro parte) de Loma Solana, Sierra de Quípar (Subbético Externo, Cehegín, Murcia)
(Sociedad Geológica de España, 2014)The stratigraphy, biostratigraphy and geochemistry (C stable isotopes and RSTE trace elements) of a succession of Valanginian age outcropping in Loma Solana (External Subbetic) is presented. The succession is composed ... -
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 ... -
Estudio preliminar de los ostrácodos del yacimiento del Eoceno inferior de Loza (Álava, Cuenca Vasco-Cantábrica)
(Sociedad Geológica de España, 2014)In this paper the preliminary study of ostracods preserved in a distinct fossiliferous level within the poorly-known lower Eocene lacustrine-palustrine succession of Loza (Álava, Basque-Cantabrian Basin) is developed. ... -
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, ... -
Precisión cronoestratigráfica y sedimentológica del yacimiento icnológico triásico en facies Buntsandstein de Bejís (Castellón, SE de la Cordillera Ibérica)
(Sociedad Geológica de España, 2014)The oldest tetrapod footprints of the Valencian Community described up to date are located in the Cañizar Formation (Desierto de las Palmas, Castellón). Most recent are those found in the village of Bejís (Castellón). ... -
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 ... -
Petrología y geoquímica de las tonalitas de Villarejo de Montalbán (Toledo)
(Sociedad Geológica de España, 2014)The tonalites of Villarejo de Montalbán are biotite-rich rocks showing felsic segregates with abundant titanite. Whole-rock geochemical and isotopic data ((87Sr/86Sr)300 = 0.7084-0.7089; εNd = -4.79, -4.80) suggest that ... -
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 ... -
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) ... -
Composición isotópica (δ13C, δ18O y δD) de perfiles mixtos de calcretas-silcretas: significado paleoambiental (Mioceno, área de Torrijos, Cuenca de Madrid)
(Sociedad Geológica de España, 2014)In this paper the isotopic stable isotopes of three calcrete-silcrete profiles are studied. The profiles correspond to the top of the Lower Miocene Unit of the SE Madrid basin and developed on fine-grained detrital ... -
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 ... -
