Optimum and robust 3D facies interpolation strategies in a heterogeneous coal zone (Tertiary As Pontes basin, NW Spain)
Coal exploration and mining in extensively drilled and sampled coal zones can benefit from 3D statistical facies interpolation. Starting from closely spaced core descriptions, and using interpolation methods, a 3D optimum ...
Fault Locking, Block Rotation and Crustal Deformation in the Pacific Northwest
We interpret Global Positioning System (GPS) measurements in the northwestern United States and adjacent parts of western Canada to describe relative motions of crustal blocks, locking on faults and permanent deformation ...
Impact of suborbital climate changes in the North Atlantic on ice sheet dynamics at the Mid-Pleistocene Transition
Early and Mid-Pleistocene climate, ocean hydrography and ice sheet dynamics have been reconstructed using a high-resolution data set (planktonic and benthic delta O-18 time series, faunal-based sea surface temperature (SST) ...
Biozonación del Paleógeno continental de la zona oriental de la Cuenca del Ebro mediante carófitas: implicaciones en la biozonación general de carófitas de Europa Occidental
Se propone una biozonación mediante carófitas de las sucesiones paleógenas (Thanetiense- Oligoceno superior) de la Cuenca del Ebro, basada en las peculiaridades de sus asociaciones paleoflorísticas. Una de las novedades ...
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 ...
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 ...
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 ...
Salt tectonics of the offshore Tarfaya Basin, Moroccan Atlantic margin
Salt tectonics play a critical role on passive margins evolution controlling aspects like structural style, subsidence patterns and thermal history, amongst others. The salt-bearing Atlantic passive margin of Morocco hosts ...
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 ...
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 ...
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 ...
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 ...
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) ...
Geomorphological, chronological, and paleoenvironmental context of the Mousterian site at Roca San Miguel (Arén, Huesca, Spain) from the penultimate to the last glacial cycle
The Roca San Miguel (RSM) archaeological site was occupied during Mousterian times. Here we present a geoarchaeological and paleoenvironmental reconstruction of the site. Five stratigraphic units (A to E) formed by different ...
Evidencias de un glaciar salino en el diapiro de Les Avellanes (NE España). Resultados preliminares.
A lo largo del cinturón surpirenaico afloran grandes masas de evaporitas triásicas (facies Keuper) formando estructuras intrusivas asociadas a los pliegues y cabalgamientos (Muñoz et al., 2018). Dentro de estas estructuras ...
Fluvio-deltaic record of increased sediment transport during the Middle Eocene Climatic Optimum (MECO), Southern Pyrenees, Spain
The early Cenozoic marine sedimentary record is punctuated by several brief episodes (<200 kyr) of abrupt global warming, called hyperthermals, that have disturbed ocean life and water physicochemistry. Moreover, recent ...
Mating and aggregative behaviors among basal hexapods in the Early Cretaceous
Among the many challenges in paleobiology is the inference and reconstruction of behaviors that rarely, if ever, leave a physical trace on the environment that is suitable for fossilization. Of particular significance are ...
