Distributed stress fluidisation: insights into the propagation mechanisms of the Abona debris avalanche (Tenerife) through a novel method for indurated deposit sedimentological analysis
(Frontiers Media, 2023-05-18)Introduction: Volcanic debris avalanches mobilise large volumes and achieve long runouts with high destructive potential. However, the propagation processes that generate them are not currently explained by theoretical ... -
Paleomagnestism of the Santa Victoria Group in the Mojotoro Range, Salta: Contributions to the paleogeographic position of Pampia in Early Paleozoic
(2018-01-01)Sedimentologic magnetofabric paleomagnetic studies were carried out on the early Ordovician La Pedrera Formation (Santa Victoria Group) in the Mojotoro Range Salta province. These studies aim at contributing to a better ... -
Isolated PdO sites on SiO2-supported NiO nanoparticles as active sites for allylic alcohol selective oxidation.
(Royal Society of Chemistry (RSC), 2023-06-19)Catalytic allylic alcohol oxidation to aldehydes is an industrial process that necessitates chemoselectivity. Surface PdO (on Pd) enables this transformation but does not represent optimal metal utilisation. Here we report ... -
Contribution of glaciers to water, energy and food security in mountain regions: current perspectives and future priorities
(Cambridge University Press (CUP), 2022-09)Mountain glaciers are crucial sources of fresh water, contributing directly and indirectly to water, energy and food supplies for hundreds of millions of people. Assessing the impact of diminishing glacial meltwater ... -
The influence of mantle hydration and flexure on slab seismicity in the southern Central Andes
(Springer Science and Business Media LLC, 2023)Knowledge of the causative dynamics of earthquakes along subduction-zone interfaces and within oceanic slabs is relevant for improving future seismic hazard assessments. Here, we combine the analysis of seismic tomography, ... -
Petrology of the explosive deposits from the April 2021 eruption of La Soufrière volcano, St Vincent: a time-series analysis of microlites
(Geological Society of London, 2024-04-01)After more than three months of lava dome extrusion, La Soufrière (St. Vincent) transitioned to a series of explosive eruptions in April 2021. Here we present a time-series petrologic analysis of the phenocryst and microlite ... -
Testing the Effect of Relative Pollen Productivity on the REVEALS Model: A Validated Reconstruction of Europe-Wide Holocene Vegetation
(MDPI AG, 2023)Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible to assess the past effects of environmental variables ... -
Release of tephra-hosted iron during early diagenesis fingerprinted by iron isotopes
(Elsevier BV, 2023-03-01)The micronutrient iron (Fe) plays a fundamental role controlling primary productivity in the upper ocean, with volcanic eruptions and deposition of airborne volcanic material (termed tephra) a potential source of Fe. Here, ... -
Thermally-induced clumped isotope resetting in belemnite and optical calcites: Towards material-specific kinetics
(Elsevier BV, 2023-03-29)The application of carbonate clumped isotope (Δ47) thermometry in deep-time is often limited by modification of the original temperature signal by thermal resetting. New modeling approaches to estimate the initial isotopic ... -
Response of dissolved organic carbon dynamics to salinity in a Constructed Fen Peatland in the Athabasca Oil Sands region
(Wiley, 2023-03-05)In northern Alberta, oil sands mining disturbs the boreal landscape, and reclamation to an ‘equivalent land capability’ is required. Industry is testing peatland construction as part of landscape reclamation. To determine ...
