Process-based forward numerical ecological modeling for carbonate sedimentary basins
Nowadays, numerical modeling is a common tool used in the study of sedimentary basins, since it allows to quantify the processes simulated and to determine interactions among them. One of such programs is SIMSAFADIM-CLASTIC, ...
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 ...
A feasible methodology for landslide susceptibility assessment in developing countries: A case study of NW Nicaragua after Hurricane Mitch
In October 1998, Hurricane Mitch triggered a large number of landslides (mainly debris flows) in Honduras and Nicaragua, resulting in a high death toll and in considerable damage to property. In recent years, a number of ...
Remote sensing and seismic data integration for the characterization of a rock slide and an artificially triggered rock fall
On May 5th, 2013 a planar rock slide (~450 m3) occurred in the village of La Riba (NE Spain), which forced the closure of the road C-240z for 6 months. This slide left a hanging block (~130 m3) suspended on the slope forcing ...
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) ...
Paleomagnetic study of the curvature of the Segre oblique zone (Southern Pyrenees).
The origin of the obliquity of the structures at the eastern end of the central South-Pyrenean salient is investigated by means of Paleomagnetism. Earlier paleomagnetic data in the area are poorly distributed and insufficient ...
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 ...
Los depósitos aluviales sintectónicos de la Pobla de Segur: alogrupos y su significado tectonoestratigráfico
El análisis estratigráfico y estructural de los conglomerados finieocenos y oligocenos de La Pobla de Segur (Formación de Collegats) localizados en los Pirineos centrales, ha permitido correlacionar diferentes episodios ...
Venas de cuarzo gigantes en el Pirineo Oriental a partir de un enfoque macroestructural
<p>La ocurrencia de venas de cuarzo es común en diferentes contextos geológicos y su estudio puede contribuir a conocer la evolución estructural y geoquímica de las rocas donde se encajan. Los mecanismos de formación de ...
Análisis morfométrico de bloques de tsunamis en la isla de Formentera, islas Baleares
Se caracterizan morfométricamente 86 bloques de grandes dimensiones ubicados sobre dos áreas de la isla de Formentera y los islotes de s'Espardell y s'Espalmador. Estos bloques se encuentran ubicados sobre acantilados ...
Basement-involved reactivation in foreland fold and thrust belts: the Alpine-Carpathian Junction (Austria)
The Late Eocene to Early Miocene Alpine-Carpathian fold-and-thrust belt (FTB) lies in the transition between the Eastern Alps and the Western Carpathians, southeast of the Bohemian crystalline massif. Our study shows the ...
On the Upper Ordovician unconformity in the Pyrenees: New evidence from the La Cerdanya area
In recent years, contradictory reports about whether or not an unconformity exists at the base of the Upper Ordovician succession of the Pyrenees have been made. In the Cerdanya area (Central Pyrenees), good outcrop evidence ...
La Formación de Bellmunt (Unidad del Cadí, Pirineo Oriental): aportaciones bioestratigráficas de los sistemas lacustres y palustres asociados
La Formación de Bellmunt es una unidad aluvial de carácter sinorogénico relacionada con el emplaiamiento de 1os mantos pirenaicos.En suzonainferior-media intercala numerosos tramos lacustres y palustres que contienen una ...
Sistemas lacustres paleógenos de Mallorca (Mediterráneo Occidental).
Dos importantes sistemas lacustres-palustres se desarrollaron durante el Paleógeno en las Baleares. En el primero de ellos, de edad Bartoniense (Eoceno medio), se formó una importante acumulación de sedimentos carbonatados ...
Terrestrial Isopods from Spanish Amber (Crustacea: Oniscidea): Insights into the Cretaceous Soil Biota.
Terrestrial isopods (Crustacea: Oniscidea) are a model group for studying the colonization of land. However, their fossil record is remarkably scarce and restricted to amber inclusions, and therefore amber deposits represent ...
In Search of the Source of the 1865-1866 Nicaraguan Earthquakes: Paleoseismic Data from the Cofradia Fault, Managua Graben (Nicaragua)
In 1865-1866, a series of catastrophic earthquakes struck Managua, Nicaragua. We present new data supporting the view that these earthquakes were caused by the seismogenic Cofradia fault. The data were collected at three ...
Sedimentary architecture of a Middle Ordovician embayment in the Murzuq Basin (Libya)
The Hawaz Formation comprises a siliciclastic, shallow to transitional marginal marine succession, deposited on the north-western cratonic margin of Gondwana during the Middle Ordovician. This unit is well documented in ...
Potential of airborne LiDAR data analysis to detect subtle landforms of slope failure: the example of Portainé, Central Pyrenees
Slope failures have been traditionally detected by field inspection and aerial-photo interpretation. These approaches are generally insufficient to identify subtle landforms, especially those generated during the early ...
Major consequences of an intense dense shelf water cascading event on deep-sea benthic trophic conditions and meiofaunal biodiversity
Numerous submarine canyons around the world are preferential conduits for episodic dense shelf water cascading (DSWC), which quickly modifies physical and chemical ambient conditions while transporting large amounts of ...
