Dense shelf water and associated sediment transport in the Cap de Creus Canyon and adjacent shelf under mild winter regimes: insights from the 2021–2022 winter
Dense shelf water cascading (DSWC) is a key oceanographic process in transferring energy and matter from continental shelves to deep ocean areas. Although intense DSWC (IDSWC) events have received most attention due to ...
3D modeling of gas hydrates distribution in South Hydrate Ridge (Cascadia accretionary prism, offshore Oregon) through geological time
South Hydrate Ridge (SHR) is an anticlinal structure that is part of the Cascadia accretionary prism, located offshore of Oregon. SHR has been the subject of multiple multidisciplinary studies and oceanographic campaigns ...
U-Pb-age from undeformed granite pebbles in Carboniferous Culm conglomerates: new geochronological constrains on the Variscan events in the Pyrenees
U-Pb ages of zircon and apatite in undeformed granite pebbles of synorogenic Carboniferous Culm conglomerates confirm the existence of an early Carboniferous (Visean to Bashkirian) magmatic event in the core of the Pyrenees. ...
Changes in lake sediment carbon accumulation rates in southwestern Canada since the mid-1800s.
Carbon (C) storage in lakes is an increasingly recognized component of the global C cycle. Yet, rates of C accumulation in lake sediments remain poorly quantified in some regions such as in Canada. This study assessed C ...
Radon levels in soil and in groundwater in the Alhama de Murcia fault area, Spain
Radon and CO₂ in groundwater, radon and thoron in soil, soil radon exhalation rates, and 14 electrical resistivity imaging were measured in the Alhama de Murcia Fault area. The study 15 aims to (i) characterize radon levels ...
The 2013 September-October seismic sequence offshore Spain: A case of seismicity triggered by gas injection?
A spatially localized seismic sequence originated few tens of kilometres offshore the Mediterranean coast of Spain, close to the Ebro river delta, starting on 2013 September 5, and lasting at least until 2013 October. The ...
Paleoseismology of the Marquesado-La Rinconada thrust system, Eastern Precordillera of Argentina
Excavated trenches at two sites across the Marquesado–La Rinconada fault system along the eastern Precordilleran front south of San Juan, Argentina, reveal the earthquake history of this rapidly urbanizing region. ...
Improved Geological Slip Rate Estimations in the Complex Alhama de Murcia Fault Zone (SE Iberia) and Its Implications for Fault Behavior
Fault slip rate is one of the most crucial parameters to characterize earthquake occurrence in fault-based seismic hazard assessments (SHA). Accordingly, paleoseismic studies have increasingly focused on constraining this ...
Drawing as a tool for representing and explaining complex structures in Foraminifera
This work considers the relevance of drawing in foraminiferal micropaleontology and how drawing has helped to understand and explain the complex architecture of foraminiferal tests. We present a brief anthology of those ...
A FORTRAN program to introduce field-measured sedimentary logs into reservoir modelling packages
Building reservoir-scale facies models of outcrops is a practice that improves the three-dimensional geological modelling of subsurface analogues. Facies modelling of outcrops can be achieved either with geostatistical or ...
From salt carapace to secondary minibasin encasement—The Bolon Secondary Minibasin, Eastern External Betics, SE Iberia
The Bolon Secondary Minibasin (BSM) evolved on the now eroded Elda Salt Sheet, which contains fragments of the diapiric roof and syn-contractional sediments. Our detailed analysis of the BSM reveals how diapir rejuvenation ...
Three-dimensional reconstruction of geological surfaces: An example of growth strata and turbidite systems from the Ainsa basin (Pyrenees, Spain)
The external and internal geometry of four turbidite systems outcropping around the Buil syncline (Ainsa basin, Spanish Pyrenees) have been reconstructed with reservoir-scale resolution in three dimensions. The irregular ...
Best-practice stochastic facies modelling from a channel fill turbidite sandstone analog (the 'Quarry outcrop', Eocene Ainsa Basin, NE Spain)
Using data from an outcrop characterization of a sandstone-rich turbidite channel fill (the so-called ‘‘Quarry outcrop’’ in the Ainsa basin), several stochastic facies models were constructed at bedscale resolution (cells ...
Macrolitter trapping in mangroves: Insights from forest structure and local community knowledge
Mangroves, globally recognized as critical coastal ecosystems, form fringe, basin, and riverine forests in tropical and subtropical coastal zones, where their aerial roots trap macrolitter carried by currents. This study ...
New early Rupelian endemic porcellaneous larger foraminifera from the Prebetic Range, westernmost Tethys. Discussion on <em>Praerhapydionina</em>.
Peneroplis peramplus n. sp. and Spirolinella emmae n. gen., n. sp. are described from the early Rupelian of the Ibi section in the Prebetic Range (southeastern Iberia). The former is a Peneroplis species of evolute annular ...
Hierarchical geocellular facies modelling of a turbidite reservoir analogue from the Eocene of the Ainsa basin, NE Spain
Geocellular models of analogues can provide with insights into modelling strategies for the subsurface, therefore a model of the outcropping Ainsa turbidite system, deposited in slope setting, was built. The modelling began ...
New Early Rupelian Endemic Porcellaneous Larger Foraminifera from the Prebetic Range, Westernmost Tethys. Discussion on <em>Praerhapydionina</em>
Peneroplis peramplus n. sp. and Spirolinella emmae n. gen., n. sp. are described from the early Rupelian of the Ibi section in the Prebetic Range (southeastern Iberia). The former is a Peneroplis species of evolute annular ...
Spatial and temporal variability in blue carbon accumulation in the largest salt marsh in British Columbia, Canada
Preserving blue carbon ecosystems, such as salt marshes, for climate change mitigation requires quantifying their carbon (C) dynamics. Boundary Bay (BB) marsh is a 222-ha salt marsh in southern British Columbia, Canada, ...
Geology of the Golobar and Rumaceo faults, Basque-Cantabrian Pyrenees
The lateral transition between different styles of deformation is crucial for understanding local-scale structures since it influences orogenic reconstructions at the crustal scale. This is especially important at the ...
