Asociaciones de foraminíferos del Messiniense y Plioceno del sector norte de la Cuenca del Bajo Segura
(2008)The Messinian and Pliocene stratigraphic record of the northern sector of the Bajo Segura Basin has been separated into three main allostratigraphic units (MI, MII and P). These units are composed of continental to marine ... -
Bioestratigrafía basada en foraminíferos planctónicos para el Mioceno superior y Plioceno de la Cuenca del Bajo Segura (Cordillera Bética oriental)
(2010)The planktonic foraminifers biostratigraphy is crucial in order to precise the timing of the main tectono- sedimentary and palaeogeographic events through the evolution of the Bajo Segura Basin. Our results indicates that ... -
Carbonatos palustres en llanuras de inundación fluviales del Plioceno-Pleistoceno (Cuenca de Guadix, Granada, España)
(2007)During its continental stage of infilling (Late Tortonian-Late Pleistocene), the Guadix Basin acted as an endorheic depression in which an axial fluvial system, fed partialy by two transverse alluvial systems, drained ... -
Comentarios al artículo Magnetoestratígrafía preliminar de los materiales pliocenos de la cubeta de Villarroya (Sierra de Cameros, La Rioja), de E. Pueyo Morer, A. Muñoz Jiménez y J.M. Parés (1996)
(Sociedad Geológica de España, 1997)In the present note we comment on the recent magnetostratigraphy dating above the Gauss/Matuyama boundary of the vertebrate locality of Villarroya. This dating is based on its supposed biochronological age and precisely ... -
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 ... -
El Paleocañón de Estepona como un rasgo morfosedimentario Plioceno-Cuaternario del margen septentrional del Mar de Alborán
(Sociedad Geológica de España, 1999)The north-western continental margin of the Alboran Sea is characterised by the development of some submarine channels systems during the Pliocene-Quaternary times. One of these systems, the Paleocanyon of Estepona, has ... -
El terciario continental del sector Alfambra-Villalba Alta, fosa de Teruel
(Sociedad Geológica de España, 2002)This paper focuses on the Tertiary deposits of the northern area of the Teruel Craben in the Alfambra-Villalba Alta area. The oldest Tertiary deposits are Palaeogene in age and outcrop very locally and unconformably on the ... -
Estratigrafía del Plioceno de la costa de Cádiz entre Chiclana y Conil
(Sociedad Geológica de España, 1990)The Pliocene sequence of the Cadiz coast between Chiclana and Conil is described. Three sedimentary units, separated by unconformities, can be distinguished. The two lower units are Lower Pliocene in age, according to ... -
Evidencias de deformación neotectónica en el sector de Lepe-La Antilla (Huelva)
Rodríguez Vidal, Joaquín
; Flores Hurtado, Enrique (Asociación Española para el Estudio del Cuaternario; Sociedad Española de Geomorfología, 1991)
Las arenas marinas de la Fm. Bonares (Plioceno inferior) de la Depresión del Guadalquivir están afectadas, en su sector más occidental, por una densa red de fracturas verticales ferruginizadas. Su análisis estadístico, al ... -
Evolución del sistema fluvial Jarama-Lozoya-Guadalix durante el Plioceno final y el Cuaternario
(Sociedad Geológica de España, 1994)This paper deals with the Jarama-Lozoya-Guadalix fluvial system evolution during the Pliocene and Pleistocene times. Duringt the Upper Pliocene and Lower Pleistocene time the Lozoya river was under incission and fluviokarst ... -
Facies fluviales y lacustres de los sedimentos finineógenos de Valdepeñas, Ciudad Real (SO de la Llanura Manchega)
(Sociedad Geológica de España, 2003)A general column of the pliocene sedimentary filling in the Valdepeñas area has been made based on MAGNA cartography and large local estratigraphic sections. This study has let us to describe the terrigenous and carbonate ... -
Las Icnitas de mamíferos del sur de Alicante (España)
(Sociedad Geológica de España, 1992)South of Alicante, in the eastern end o f Sierra del Colmenar, an outcrop of bird and mammal fossil footprints (icnites) is well exposed, the latter show in gan excellent state of preservation. In this paper the mammal ... -
Interpretación paleoclimàtica de las varvas pliocenas de la Cuenca de Villarroya (Sierra de Cameros, La Rioja)
(Sociedad Geológica de España, 2001)This is a study of an extremely good outcrop of 1745 varves in the Villarroya Pliocene Basin (Spain). We have used the periodogram approach for estimating power spectra and periodicities of about 1 2, 6-7 and 2-3 years ... -
Isótopos estables de carbono y oxígeno de los rellenos de calcita (falsa ágata) y su interés paleoambiental
(Sociedad Geológica de España, 1988)The isotopic composition of modern calcite fills (onyx marble) in fractures and related caves is studied. Carbon and oxygen stable isotopes in this material are similar to the vadose speleothems (stalactites and stalagmites) ... -
La sección de San Miguel de Salinas (Cuenca del Bajo Segura). Significado paleoambiental de las asociaciones de foraminíferos en relación con la Crisis de Salinidad del Messiniense
(2009)In the composite section of San Miguel de Salinas the following synthems are represented: MI (preevaporitic Messinan), MII (syn-evaporitic Messinian) and P (post-evaporitic Pliocene). The foraminiferal assemblages of ... -
La sección Messiniense - Plioceno de Crevillente (Cordillera Bética oriental): expresión de la crisis de salinidad del Mediterráneo
(Sociedad Geológica de España, 2001)A composite stratigraphic section in Crevillente (eastern Betic Cordillera) is studied. It represent a complete stratigraphical and paleontological record of the Messinian and Lower Pliocene. Two discontinuity surfaces ... -
La sedimentación de afinidad Lago Mare (Messiniense) y la transgresión del Plioceno en Alicante (Cuenca del Bajo Segura)
(2006)In the Alicante city and surrounding sectors the uppermost par t of the Messinian sequence (MII unit) is characterized by the stacking of shallowing upward cycles. The complete cycle star ts with beach sandstones and ... -
