Early Cretaceous termites in amber from northern Spain (Isoptera).
Two virtually complete termites in Lower Cretaceous amber from the Peñacerrada I outcrop, Spain, are described and figured, representing the most well-preserved Isoptera yet discovered from the Albian stage. The material ...
Modeled Buoyancy of eggs and larvae of the deep-sea shrimp Aristeus antennatus (Crustacea: Decapoda) in the northwestern Mediterranean Sea
Information on the buoyancy of eggs and larvae from deep-sea species is rare but necessary for 30 explaining the position of non-swimming larvae in the water column. Due to embryonic 31 morphology and ecology diversities, ...

En este trabajo se explicitanlos resultados de los análisis esporopoiínicos realizados en múltiples niveles del Cretácico terminal-Terciario basa1 en el sector N:E. de la Península Ibérica. Los datos de los que actualmente ...
The transition from thick-skinned to thin-skinned tectonics in the Basque-Cantabrian Pyrenees: the Burgalesa Platform and surrondings
Interpretation of seismic data in the margins of the Burgalesa Platform in the Basque-Cantabrian Pyrenees has allowed proposition of a new structural model that combines different modes of deformation during oblique tectonic ...
Timing of wet episodes in Atacama Desert over the last 15 ka. The Groundwater Discharge Deposits (GWD) from Domeyko Range at 25ºS.
A chronologically robust reconstruction of timing and dynamics of millennial time scale wet episodes encompassing the entire Atacama Desert during the last 15 ka has been constructed. To accomplish this, a new composite ...
Approach to the Lower Pliocene marine-continental correlation from southern Spain. The micrommamal site of Alhaurín el Grande-1 (Málaga Basin, Betic Cordillera, Spain)
A new micromammal site at Alhaurín el Grande (Málaga, southern Spain) located above early Pliocene marine deposits allows an approach to the marine-continental correlation for this age. The early Pliocene marine filling ...
Multidetachment analogue models of fold reactivation in transpression: The NW Persian Gulf
Two deformation events have been documented in the NW Persian Gulf during the Late Cretaceous and the Late Cenozoic. The most distinctive feature in this part of the Persian Gulf is the reactivation of the Late Cretaceous ...
Fauna malacológica del Pleistoceno superior en el Abric Romani (Capellades, Barcelona)
Aquatic and terrestrial gastropod shells, recovered by water sieving of the sediments from the Middle Paleolithic sequence C.III, Level H, at the RomanI rockshelter, have confirmed the past waterlogged conditions of a ...
Landscape Systems and Human Land-Use Interactions in Mediterranean Highlands and Littoral Plains during the Late Holocene: Integrated Analysis from the InterAmbAr Project (North-Eastern Catalonia).
The main goal of the InterAmbAr reseach project is to analyze the relationships between landscape systems and human land-use strategies on mountains and littoral plains from a long-term perspective. The study adopts a high ...
Nuevos datos sobre la biozonación del Burdigaliense continental de la cuenca del Vallès-Penedès
En esta nota preliminar se dan a conocer dos nuevos yacimientos de microvertebrados situados en la cuenca del Valles-Penedes. La asociación de Roedores sita ambas localidades (Can Mar Vell y Can Julia) en la MN-4, equivalente ...
Some fundamental aspects of palentological methodology: its problems and incidence
Two trends which presently exist in relation to the concept of Paleontology are analyzed, pointing out some of the aspects which negative influence. Various reflections are made based on examples of some of the principal ...
Sintesis biostratigrafica de la fosa de la Cerdanya (Pirineos orientales).
En el presente trabajo se describen las principales características estratigráficas y sedimentológicas del relleno de la fosa de la Cerdanya. A partir de éstas se han diferenciado dos unidades: la Unidad Neógena Inferior ...
A 70,000 year multiproxy record of climatic and environmental change from Rano Aroi peatland (Easter Island)
The Rano Aroi mire on Easter Island (also known as Rapa Nui; 27°09′S, 109°27′W, 430 m above sea level) provides a unique non-marine record in the central South Pacific Ocean for reconstructing Late Pleistocene environmental ...
Valoración patrimonial de los yacimientos del Mioceno inferior del Barranco de Campisano de la Cuenca de Ribesalbes-Alcora (Araia d'Alcora, Castelló, España)
En el presente trabajo se realiza una valoración patrimonial del conjunto de yacimientos del Mioceno inferior del barranco de Campisano (cuenca de Ribesalbes-Alcora). Los resultados obtenidos al calcular los parámetros ...
Evolutionary history, biogeography, and extinction of the Cretaceous cheirolepidiaceous conifer, Frenelopsis
Frenelopsis Schenk (family Cheirolepidiaceae†) was among the most widespread conifer genera and a dominantelement of wetland ecosystems in low to mid-palaeolatitudes in the the Northern Hemisphere. It was also one ofthe ...
Slope instability along the northeastern Iberian and Balearic continental margins
This paper gathers the available information on submarine landslides identified in the northeastern Iberian continental margin and presents new data on both already known landslides and new, previously unknown ones. The ...
Rapid response of benthic deep-sea microbes (viruses and prokaryotes) to an intense dense shelf water cascading event in a submarine canyon of the NW Mediterranean Sea
A major dense shelf water cascading (DSWC) event occurred in 2005 downward the Cap de Creus Canyon (Gulf of Lion, NW Mediterranean Sea), which caused a significant change in environmental parameters and biological components. ...
A review of the granite concept through time
Granitic rocks are ubiquitous worldwide in ancient and active tectonic settings, representing powerful sources of information about the Earth's past and present geodynamic behaviour. Numerous recent milestones fostering ...
El Dr. Lluís Via Boada, una vida fecunda
El Dr. Lluís Via Boada, nació en Vilafranca del Penedes en octubre de 1910, y empezó sus estudios eclesiásticos en el Seminario de Barcelona en setiembre de 1925.
Fault interpretation in seismic reflection data: an experiment analysing the impact of conceptual model anchoring and vertical exaggeration
The use of conceptual models is essential in the in- terpretation of reflection seismic data. It allows interpreters to make geological sense of seismic data, which carries inherent uncertainty. However, conceptual models ...
