Asociaciones de foraminíferos bentónicos y evolución paleoambiental del Plioceno inferior en el sector de Elche-Crevillente (Cuenca del Bajo Segura, Alicante): Resultados preliminares
(Sociedad Geológica de España, 2004)Benthic foraminifer assemblages of two Early Pliocene sections located between Elche and Crevillente are studied. In both sucessions three stratigraphic units are distinguished: P0 Unit, littoral conglomerates (transgressive ... -
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 ... -
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 ... -
Estratigrafía y biomagnetoestratigrafía del Messiniense en la sección del Garruchal (Cuenca del Bajo Segura). Implicaciones para la crisis de salinidad del Mediterráneo
(2006)The Messinian and Pliocene stratigraphic record in the Garruchal section (Bajo Segura Basin) has been divided into three allostratigraphic units, whose timing were established through combined calcareous nannoplankton ... -
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 ... -
Pistas fósiles asociadas a la discontinuidad fini-Messiniense en el margen norte de la Cuenca del Bajo Segura (SE España)
(2009)A detailed analysis of the Upper Messinian-Lower Pliocene at the northern border of the Bajo Segura Basin (BSB) has been carried out. Trace fossils of firm- and rockground were collected, aiding in the recognition of ... -
¿Por qué son tan diferentes las sierras de Crevillente y Abanilla?
(Sociedad Geológica de España, 2004)The Crevillente and Abanilla mountain ranges form the same structural lineation but show a quite different morphology. The first one is made by calcareous rocks mainly jurassic and cretaceous likewise the Abanilla is ... -
Rasgos morfológicos e icnológicos de la superficie erosiva del límite Messiniense-Plioceno (Sierra del Colmenar, Alicante). Relación con la crisis de salinidad del Mediterráneo
(Sociedad Geológica de España, 2004)The Messinian/Pliocene boundary in the Sierra del Colmenar (Alicante) is represented by an erosional surface called the end-Messinian unconformity. This erosional surface cuts the coastal and lagoonal deposits of the ... -
Registro del evento 8.2 ka en la plataforma continental de Alicante (SE, España)
(2009)High resolution seismic profiles of the Alicante continental shelf have been studied identifying a seismic prism which top at about -20 m below today sea-level. The prism is covered by recent sediments and can be interpreted ... -
Trazas afines a Imbrichnus wattonensis HALLAM de edad Albiense en el Prebético de Alicante (Serra Celada)
(Sociedad Geológica de España, 2001)Albian trace fossils related to Imbrichnus wattonensis HALLAM were studied in the "Prebetico de Alicante". Meniscate backfilling with imbricated sandy/ruditic clasts characterized this ichnogenus with regard to Taenidium., ...
