La estratigrafía del Mioceno entre Altafulla y Torredembarra (província de Tarragona)
Se da la estratigrafa de dos secciones del Mioceno en el sector de Altafulla-Torredembarra. Las dos secciones se caracterizan por su elevado contenido en COsCa.
Morfología de las colonias de briozoos en relación con la hidrodinámica del medio sedimentario
La formación de arenas y calcarenitas bioclásticas de la base de la transgresión tortoniense en Alhama de Granada contiene varios tipos de formas coloniales y de acúmulos de briozoos de características peculiares, nuevas ...
Geological evidences of surface rupture related to a seventeenth century destructive earthquake in Betic Cordillera (SE Spain): constraining the seismic hazard of the Alhama de Murcia fault
Constraining the date of the last major event occurred in a fault is of paramount importance in probabilistic seismic hazard assessment when time-dependent models are considered. Eight of the twelve destructive earthquakes ...
Deglacial Mediterranean-basins link: old carbon-enriched eastern waters and collateral consequences for western aragonite mounds growth
A Mediterranean Thermohaline Circulation slowdown related to deglaciation and monsoon dynamics have largely been discussed, but it yet remains insufficiently constrained. With the aim of investigating changes in water mass ...
Long-proboscid brachyceran flies in Cretaceous amber (Diptera: Stratiomyomorpha: Zhangsolvidae)
The monophyletic family Zhangsolvidae comprises stout-bodied brachyceran flies with a long proboscis and occurring only in the Cretaceous, originally known in shale from the Early Cretaceous Laiyang Formation (Fm.) in China ...
Hydroclimate variability during the last 2700 years based on stalagmite multi-proxy records in the central-western Mediterranean
This study presents the first high-resolution speleothem-based hydrological reconstruction for much of the last 2.7 kyr in the central-western Mediterranean. The paleohydrological information comes from a combination of ...
New Insights on the Sorbas Basin (SE Spain): the onshore reference of the Messinian Salinity Crisis
The Sorbas Basin is the land reference of the Messinian Salinity Crisis (MSC) that affected the Mediterranean Sea in the latest Miocene. Its stratigraphy has been re-visited using calcareous nannofossils and planktonic ...
Large-scale structure of an Intraplate Fold-and-Thrust Belt: The Iberian Chain.
The Iberian Chain is an intraplate fold-and-thrust belt developed during the late Eocene to Miocene because of the contractional inversion of the Iberian Mesozoic Basins. Its dominant trend is NW-SE, but E-W-, NE-SW- and ...
Influence of Syntectonic sedimentation and décollement rheology on the geometry and evolution of orogenic wedges: analog modelling of the Kuqa Fold-and-thrust belt (NW China)
Contractional deformation in the outer parts of fold‐and‐thrust belts is in part controlled by the presence of syntectonic sediments and multiple décollements (e.g., the Apennines, the Appalachians, the Pyrenees, the Zagros, ...
Climate changes and cultural shifts on Easter Island during the last three millennia
Easter Island's cultural shifts have been explained mostly by anthropogenic forcing and climate changes have been dismissed as relevant drivers of societal change. Recent findings demand a more complex scenario in which ...
Caracterización meteorológica de las camapañas estivales 1994-95 y 1995-96, en la isla Livingston (Shetland del Sur).
En este trabajo se presenta el análisis de los datos de temperatura, radiación global, radiación difusa y humedad relativa, simultáneos, registrados en la isla Livingston durante las campañas de verano de 1994-95 y 1995-96. ...
Surface NMR survey on Hansbreen Glacier, Hornsund, SW Spitsbergen (Norway)
Glaciers are widely spread on polar and sub-polar regions but also on middle latitude mountains, where cold-dry type glaciers, polythermal glaciers and temperate-wet glaciers are respectively present. Polythermal glaciers ...
Acoustic and seismic imaging of the active Adra Fault (NE Alboran Sea): In search for the source of the 1910 Adra Earthquake
Recently acquired swath-bathymetry data and high-resolution seismic reflection profiles offshore Adra (Almería, Spain) reveal the surficial expression of a NW-SE trending 20 km-long fault, which we termed the Adra Fault. ...
Tsunami boulders on the rocky coasts of Ibiza and Formentera (Balearic Islands)
Large boulders have been found in marine cliffs from 7 study sites on Ibiza and Formentera Islands (Balearic Islands, Western Mediterranean). These large boulders of up to 43 t are located on platforms that form the rocky ...
Sedimentology of a 'non-actualistic' Middle Ordovician tidal-influenced reservoir in the Murzuq basin (Libya)
The subsurface of the highly productive Murzuq Basin in southwest Libya remains poorly understood. As a consequence, a need exists for detailed sedimentological studies of both the oil-prone Mamuniyat Formation and Hawaz ...
Revisiting the role of high-energy Pacific events on the environmental and cultural history of Easter Island (Rapa Nui)
Pacific islands are spread over thousands of kilometers of the Oceanic Basin and are characterized by similar ecological features but very diverse geologic origins, from steep volcanoes to flat coral atolls. Several climatic ...
Lunulites bugei (Bryozoa Cheilosmata) nueva especie del nummulítico inferior de Tremp (Lérida)
Solamente dos especies del género Lunulifes LAMACK han sido reconocidas en el Terciario español, ambas en Cataluña. Se trata de Lunulites punctatirs LEYMERIE, citado de Santa Margarita de Montbui, Sant Martí de ...
Geometría 3d, Estructura y formación de la cuenca del Duero en el contexto geodinámico del orógeno pirenaico
The Duero foreland basin is characterized by a large synformal geometry formed by the lithospheric flexure and northward subduction of the Iberian crust underneath the Cantabrian-European crust. Basin structure is represented ...
Collapse of the Mediterranean Thermohaline Circulation during the Sapropel S1: New insights from Nd isotopes
Sapropel events, organic-rich sedimentary layers that typically appear in the E-Mediterranean, have been often attributed to a combination of enhanced biological production in the surface ocean as well as a deficit in ...
Descripción geoquímica y geocronológica de secuencias volcánicas neogenas de Trasarco, en el extremo oriental de la Cadena Volcánica Transversal del Quevar (Noroeste de Argentina)
Se realizaron 34 nuevas dataciones K/Ar y 39 análisis geoquímicos de elementos mayoritarios, trazas y tierras raras, que implican n u evas aportaciones sobre las secuencias volcánicas neógenas de trasarco pertenecientes a ...
