Análisis numérico de la distribución de trazas de bioturbación. Un ejemplo de la Unidad de la Mola (Zonas Externas de las Cordilleras Béticas, provincia de Alicante)
(Sociedad Geológica de España, 1996)The application of numerical methods to the study of the distribution of trace fossil in hardground surfaces appears scarcely in the previous bibliography, mainly because these traces usually have a random distribution not ... -
Bauxitas kârsticas de la Sierra de Boada (Sierras Marginales surpirenaicas, Alös de Balaguer, Lleida)
(Sociedad Geológica de España, 1994)One of the most important bauxite site in the Spanish Pyrenees is the Sierra de Boada which is analyzed in this note. The bauxites are located between Middle Jurassic dolostones and Upper Cretaceous sandstones. They are ... -
Calizas de briozoos del Oligoceno superior-Mioceno inferior: Implicaciones paleoambientales (Subbético Externo, Sierra de Cabra, provincia de Córdoba)
(2013)Los briozoos son buenos indicadores paleoambientales, principalmente en carbonatos de aguas marinas templadas y frías. Parámetros paleoambientales como temperatura, salinidad, energía del agua, carácter del sustrato y ... -
De calizas hemipelágicas a calizas de plataforma somera: un ejemplo de facies de transición en el Jurásico Medio. Sección del Sur del San Cristóbal (Subbético, Jaén)
(Sociedad Geológica de España, 2005)An excellent stratigraphic section of the Middle Jurassic showing the record of the transition facies from hemipelagic (Baños Fm) to oolitic shallow platform limestones (Jabalcuz Fm) in the Intermediate Domain of the ... -
Calizas oolíticas entre facies pelágicas en el Jurásico medio de Iznájar (Prov. de Córdoba, Subbético): significado paleogeográfico y paleobati métrico
(Sociedad Geológica de España, 2001)On the top of the Zegrí Fm (Aalenian-Bajocian) oí the Median Subbetic in the Iznajar area (south of the Córdoba province) oolitic limestones outcrop, interbedded between pelagic facies. These oolitic limestones were ... -
Cicatriz de slump en rocas pelágicas del Jurásico: su relación con el subvolcanismo (Priego de Córdoba, Zona Subbética)
(Sociedad Geológica de España, 2001)In areas of the Median Subbetic, as in the Sierra of Priego in the southeast of the province of Córdoba, outcrops of Jurassic subvolcanic basic igneous rocks appear. In this area the pelagic sedimentation, has been controlled ... -
Costras ferromanganesíferas pelágicas inducidas por comunidades bentónicas microbianas en el límite Jurásico Medio-Superior (Subbético Externo, provincia de Córdoba)
(2010)A hardground with Fe-Mn crusts of an important Middle-Upper Jurassic stratigraphic discontinuity in the External Subbetic has been analysed. These are mainly hydrogenetic-biogenic crusts induced by the activity of benthic ... -
El Cretácico Inferior de la Sierra de Jódar-Bedmar (Prebético de Jaén, Cordillera Bética): facies, bioestratigrafía e interpretación paleoambiental
(Universidad de Huelva, 2012)El Prebético de Jaén está constituido por un conjunto de unidades tectónicas aisladas, compuestas principalmente por calizas del Cretácico Inferior. En este trabajo se analiza una de ellas, la Sierra de Jódar-Bedmar. ... -
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 ... -
Estructuras sedimentarias de deformación originadas por licuefacción en depósitos de tormentas (Mioceno de la Cuenca del Guadalquivir, provincia de Jaén)
(Sociedad Geológica de España, 1996)Soft-sediment deformation structures related with hummocky cross stratification appear in the Upper Miocene calcarenites of the Guadalquivir Basin. They are analysed and after consider their different possible genetic ... -
Influencia del subvolcanismo en la sedimentación pelágica del Jurásico medio (Sierra de San Pedro, provincia de jaén, Subbético medio)
(Sociedad Geológica de España, 1999)In areas of the Median Subbetic, as in the middle Jurassic of the Sierra of San Pedro in the southwest of the province of Jaen, important outcrops of basic volcanic and subvolcanic rocks appear. In this area the sedimentation, ... -
Interaction between sedimentation and submarine volcanism (Jurassic, Subbetic, Southern Spain)
(Sociedad Geológica de España, 2000)Se estudia la relación entre vulcanismo submarino y sedimentación carbonatada principalmente pelágica en el margen continental pasivo que actualmente aflora en el Subbético. Existen dos grupos principales de relación entre ... -
La Formación Milanos en el Subbético Medio (Jurásico superior): definición y descripción
(Sociedad Geológica de España, 1996)The Milanos Fm (Upper Kimmeridgian-Tithonian) is defined and characterised as a new formation belonging to the Middle Subbetic (External Zones of the Betic Cordillera). It is composed by marly limestones, marls and ... -
Las discontinuidades del límite Dogger-Malm: estructuras y lagunas estratigráficas asociadas (Subbético oriental; provincias de Alicante y Murcia)
(Sociedad Geológica de España, 1995)The Dogger-Malm boundary unconformities show different structures in the Eastern Subbetic outcrops. They are identified by the presence of characteristic fossils associated to the hardgrounds, two types of ichnofossils ... -
Liesegang rings in pelagic limestones: genetic considerations
(Sociedad Geológica de España, 2000)Liesegang rings have been recognized in Middle Jurassic pelagic marly limestones of the Subbetic, Southern Spain. The rings of these structures consist of iron hydroxide concentrations and/or small textural changes and are ... -
Microcodium en calizas del Eoceno Medio (Luteciense) de la Sierra de la Pila (Prebético Interno, Murcia)
(2008)Microcodium is a calcitic microfeature, mainly interpreted as root calcification products of terrestrial plants on carbonate-rich substrates, that is abundant in Paleogene successions of the peri-Tethyan realm. In the ... -
Nuevos datos y modelo genético sobre brechas jurásicas generadas en relación con fallas transcurrentes (Subbético Externo. Provincia de Córdoba)
(Sociedad Geológica de España, 1989)In the External Subbetic, Upper Jurassic coarse breccias organized in lenticular sedimentary bodies prograding to the west, are genetically relationed to N-S transcurrent faults affecting to the basin to the end of the ... -
Paleofosa Tectónica con Relleno de Ammonítico Rosso del Jurásico Superior (Subbético Externo; provincia de Córdoba)
(Sociedad Geológica de España, 1989)A recurrence in the Upper Jurassic Ammonitico Rosso facies sequence of the External Subbetic is described and interpreted as the deposition in the two blocks of an active Jurassic fault, in account of the features associated ... -
