El margen continental catalán (II): Evolución tectonosedimentaria y registro paleobiológico
Los presentes segundo a cuarto números junto con el primero del volumen 29 de Acta Geologica Hispanica, forman parte de un conjunto temático centrado en 'El margen continental catalán'. Estos números especiales tienen por ...
Sediment transport to the deep canyons and open-slope of the western Gulf of Lions during the 2006 intense cascading and open-sea convection period
An array of mooring lines deployed between 300 and 1900 m depth along the Lacaze-Duthiers and Cap de Creus canyons and in the adjacent southern open slope was used to study the water and sediment transport on the western ...
Nuevos datos magnetoestratigráficos del tránsito Oligoceno-Mioceno en el sector SE de la Cuenca del Ebro (provincias de Lleida, Zaragoza y Huesca, NE de España)
A partir de la obtención del registro de la polaridad magnética en los sedimentos aluviales y lacustres pertenecientes a dos secciones del SE de la Cuenca del Ebro (Mina Pilar y Valcuerna, situadas en el Valle del Ebro, ...
Los Ciprínidos (Pisces) del sistema lacustre Oligocénico-Miocénico de los Monegros (sector SE de la cuenca del Ebro, provincias de Lleida, Tarragona, Huesca y Zaragoza)
El material de dientes faringeos de Ciprinidos procedentes de las sucesiones lacustres del Oligoceno superior y Aquitaniense inferior del sector SE de la cuenca del Ebro es atribuido a Rutilus antiquus n.p. Esta nueva ...
Numerical modeling of the dispersion and accumulation of marine litter from the Dniester River in coastal areas of the northwestern Black Sea
This study investigates the transport and accumulation of Floating Marine Litter (FML) in the northwestern Black Sea, with a focus on the influence of the Dniester River and regional circulation patterns, including the ...
Interplay of downbuilding and gliding in salt-bearing rifted margins: insights from analogue modelling and natural case studiesInterplay of downbuilding and gliding in salt-bearing rifted margins: insights from analogue modelling and natural case studies
Our analogue modelling programme simulates a thermally subsiding rifted margin with a regional late syn-rift to early post-rift salt basin. End-member models included i) pure downbuilding in a confined salt basin and ii) ...
Primary drivers of dune cover and shoreline dynamics: A conceptual model based on the Iberian Atlantic coast
Coastal dunes evolve in direct response to primary drivers, such as wind and waves, which can significantly influence the landscape. Here, we examine the effects of the wind and wave regimes on the vegetation cover and ...
The vanishing and the establishment of a new ecosystem on an oceanic island - anthropogenic impacts with no return ticket
A multiproxy approach was applied to a sediment core retrieved from the deep crater lake Funda, located in the middle of the North Atlantic Ocean on Flores Island, Azores archipelago (Portugal). The purpose of this study ...
Atmosphere-ocean linkages in the eastern equatorial Pacific over the early Pleistocene
Here we present a new set of high-resolution early Pleistocene records from the eastern equatorial Pacific (EEP). Sediment composition from Ocean Drilling Program Sites 1240 and 1238 is used to reconstruct past changes in ...
New insights into the enigmatic Cretaceous family Spathiopterygidae (Hymenoptera: Diaprioidea)
The Cretaceous family Spathiopterygidae (Hymenoptera: Diaprioidea), containing five species in four genera, showed a wide distribution from the upper Barremian to the Turonian. We describe two new representatives of the ...
Los vertebrados fosiles del Abocador de Can Mata (els Hostalets de Pierola, l'Anoia, CataluÑa), una sucesion de localidades del Aragoniense superior (MN6 y MN7+8) de la cuenca del Valles-Penedes. CampaÑas 2002-2003, 2004-2005
Se presenta una síntesis del registro de vertebrados fósiles del Abocador de Can Mata (els Hostalets de Pierola, cuenca neógena del Vallès-Penedès), con especial énfasis en los aspectos taxonómico y bioestratigráfico. Este ...
Latest Cretaceous palaeogeographic evolution of northeast Iberia: Insights from the Campanian continental Montalbán subbasin (Spain)
This work characterizes for the first time the 500–700 m-thick uppermost Cretaceous continental sedimentarysuccession of the Allueva Fm recorded in the northeastern margin of the Iberian basin, in the Montalb´an ...
Effect of past century mining activities on sediment properties and toxicity to freshwater organisms in northern Sweden
The release of toxic metals from local mining activities often represents a severe environmental hazard for nearby lake ecosystems. Previous studies on the impact of mining activities and the recovery thereof have primarily ...
El Patrimonio paleontológico en los museos y colecciones visitables de Cataluña: evaluación de su gestión
La riqueza del patrimonio paleontológico de Cataluña ha hecho que la Paleontología catalana haya tenido un importante recorrido que se remonta a la segunda mitad del siglo XIX . Este desarrollo histórico ha originado que ...
Papel de las fallas extensivas de piel gruesa pre-existentes en la deformación de piel fina afectando a un margen pasivo invertido con tectónica salina (Prebético oriental)
El Prebético de Jumilla (SE Iberia), se caracteriza por una deformación multiepisódica desde el Pérmico- Triásico hasta la actualidad. Esta evolución geodinámica incluye un episodio extensivo (Pérmico-Triásico al Cretácico ...
Carbonate and organic matter sedimentation and isotopic signatures in Lake Chungará, Chilean altiplano, during the last 12.3 kyr.
Sediments in lakes in the Andean volcanic setting are often made up of diatomaceous ooze together with volcaniclastics and small amounts of carbonates. Despite their scarcity, carbonates along with organic matter provide ...
Prospects for Paleoseismology in Spain
Paleoseismology is the study of prehistoric earthquakes, especially their location, timing and size. Paleoseismology and Neotectonics should not be confused. Whereas Neotectonics deals with general crustal deformation in ...
Empirical α-β runout modelling of snow avalanches in the Catalan Pyrenees.
A variation in the α−β model which is a regression model that allows a deterministic prediction of the extreme runout to be expected in a given path, was applied for calculating avalanche runout in the Catalan Pyrenees. ...
Señales de depredación en los Gastropoda procedentes de un yacimiento pliocénico de Molins de Rei (Barcelona). Implicaciones paleoecológicas
En la presente nota se da una lista ampliada de la fauna malacológica del yacimiento pliocénico de la Plaça de les Bruixes (Molis de Rei, Barcelona). Los fenómenos de coacción que se describen nos muestran su utilidad a ...
Chronostratigraphy and tectono-sedimentary history of the Eastern South Pyrenean foreland basin (Ripoll Syncline North-East Spain)
This paper contributes to an understanding of the tectono-sedimentary evolution of the South Pyrenean foreland system by reviewing the chronostratigraphicframework of the basin infill in its eastern sector. Six sections ...
