Reply to the Comment on Subsidence analysis of salt tectonics-driven minibasins (Northern Calcareous Alps, Austria), published on Basin research 2020:00: 1-23 doi:10.1111/bre.12500.
We kindly take the opportunity to reply to the comments raised by Schöllnberger (2021) on our recent publication “Subsidence analysis of salt tectonics-driven carbonate minibasins (Northern Calcareous Alps, Austria)“ by ...
L'Estudi geològic de la Caserna de St. Pau (Barcelona)
L'estudi geològic de la zona consta deis apartats següents: a)Determinar la composició deis materials i la seva procedència. b)Determinar l'estratigrafia per tal de situar les troballes arqueològiques dins d'una escala ...
First evidence of paleoearthquakes along the Carboneras Fault Zone (SE Iberian Peninsula): Los Trances site
Seismogenic faults that have not produced historical large earthquakes remain unnoticed and, thus, are dangerously left out from seismic hazard analyses. The seismogenic nature of the Carboneras Fault Zone, a left-lateral ...
Statistical grid-based facies reconstruction and modelling for sedimentary bodies. Alluvial-palustrine and turbiditic examples
The geological community is increasingly aware of the importance of geological heterogeneity for managing subsurface activities. In sedimentary bodies, facies distribution is an important factor constraining geological ...
Reflexiones a partir de la catástrofe de Mocoa, Colombia
Ya se han contabilizado más de 250 muertos y cientos de desaparecidos por las inundaciones y deslizamientos desencadenadas por las fuertes lluvias que se concentraron la noche del viernes 31 de marzo en la ciudad de Mocoa, ...
Biogeochemical processes controlling oxygen and carbon isotopes of diatom silica in Late Glacial to Holocene lacustrine rhythmites
Biogeochemical cycles and sedimentary records in lakes are related to climate controls on hydrology and catchment processes. Changes in the isotopic imposition of the diatom frustules (δ 18 O diatom and δ 13 C diatom ) in ...
The late Pleistocene and Holocene glaciation in the Pyrenees: A critical review and new evidence from 10Be exposure ages, south-central Pyrenees.
A compilation and a critical assessment of the 14C data set available show that the chronology of glacial events in the Pyrenees is not well constrained. After reviewing the literature on glacial reconstruction, we suggest ...
Lacustrine sedimentation in active volcanic settings: the Late Quaternary depositional evolution of Lake Chungará (northern Chile)
Lake Chungara´ (18 15¢S, 69 09¢W, 4520 m above sea-level) is the largest (22Æ5 km2) and deepest (40 m) lacustrine ecosystem in the Chilean Altiplano and its location in an active volcanic setting, provides an opportunity ...
Particle sources and downward fluxes in the Eastern Fram Strait under the influence of the West Spitsbergen Current
The carbon cycle of the Arctic Ocean is tightly regulated by land-atmosphere-cryosphere-ocean interactions. Characterizing these environmental exchanges and feedbacks is critical to facilitate projections of the carbon ...
Abellaite, NaPb2(CO3)2(OH), a new supergene mineral from the Eureka mine, Lleida province, Catalonia, Spain
The new mineral abellaite (IMA 2014-111), ideally NaPb2 (CO3)2 (OH), is a supergene mineral that was found in one of the galleries of the long-disused Eureka mine, in the southern Pyrenees (Lleida province), Catalonia, ...
Linking sedimentation rates and large-scale architecture for facies prediction in nonmarine basins (Paleogene, Almazán Basin, Spain)
This paper focuses on the relationships between the large-scale stratigraphic architecture of the Almazán basin infill and the sedimentation rates (SR) calculated for precise time intervals. Our aim is to improve the ...
An exceptionally long paleoseismic record of a slow-moving fault: the Alhama de Murcia fault (Eastern Betic Shear Zone, Spain)
Most catastrophic earthquakes occur along fast-moving faults, although some of them are triggered by slow-moving ones. Long paleoseismic histories are infrequent in the latter faults. Here, an exceptionally long paleoseismic ...
Active Faulting, Submarine Surface Rupture, and Seismic Migration Along the Liquiñe‐Ofqui Fault System, Patagonian Andes
The intra‐arc Liquiñe‐Ofqui Fault System (LOFS) is an active transpressive fault zone located in the Patagonian Andes of Chile. In 2007, a seismic sequence occurred in the Aysén Fjord region of Chilean Patagonia along the ...
Numerical modelling of inversion tectonics in fold-and-thrust belts
This work presents numerical experiments of inversion of rift basins and consequent sub-thrust imbrication in tectonic wedges. Half-graben basins initially develop and then are covered with a post-rift sequence bearing a ...
Ten years in the dump: An updated review of the Miocene primate-bearing localities from Abocador de Can Mata (NE Iberian Peninsula)
More than ten years of paleontological fieldwork during the enlargement of the Can Mata Landfill (Abocador de Can Mata [ACM]), in els Hostalets de Pierola (Vallès-Penedès Basin, NE Iberian Peninsula) led to the recovery ...
Las biozonas de nummulitidos del Paleoceno Superior-Eoceno Inferior de la Cuenca Pirenaica
Se propone una nueva biozonación de nummulítidos para el Paleoceno-Eoceno Inferior de la Cuenca Pirenaica. Las principales aporlaciones son: a) caracterización de una nueva biozona para el Tanetiense inferior, b) redefinición ...
Pressuremeter test in glaciated valley sediments (Andorra, Southern Pyrenees). Part one: An improved approach to their geomechanical behaviour
The hyperelastic and hypoplastic behaviour of type 3 curves derive from previous hyperplastic be haviour from type 2 curves, while hyperplasticity of type 2 in turn derive from the elastic behaviour oftype 1 curves. The ...
Flank stability and processes off the western Canary Islands: a review from El Hierro and La Palma
The morphological characterisation of the western submarine island flanks of El Hierro and La Palma differentiates four type-zones that may give new insights into the evolution of oceanic island slopes. The different ...
Snow avalanche speed determination using seismic methods
We present a new method to determine the average propagation speed of avalanches using seismic techniques. Avalanche propagation speeds can reach 70 m/s and more, depending on a wide range of factors, such as the characteristics ...
Uso del ángulo de vuelco en la predicción temporal de desprendimientos de rocas
On December 3, 2013 occurred the biggest rockfall ever recorded in the pilot study area of Puigcercós scarp (Lleida, Catalonia) since the start of LiDAR monitoring on November 2007. This event, with a volume of 1093 m3, ...
