Exploring available landslide inventories for susceptibility analysis in Gipuzkoa province (Spain)
(Springer, 2023-07)Similar to many mountainous regions of the world, landslides are a recurrent geological hazard in the Gipuzkoa province (northern Spain) that commonly cause damage to communication infrastructure, such as roads and railways. ... -
Extraordinary Human Energy Consumption and Resultant Geological Impacts Beginning Around 1950 CE Initiated the Proposed Anthropocene Epoch
(Springer, 2020-10-16)Growth in fundamental drivers-energy use, economic productivity and population-can provide quantitative indications of the proposed boundary between the Holocene Epoch and the Anthropocene. Human energy expenditure in the ... -
Fast-running theropods tracks from the Early Cretaceous of La Rioja, Spain
(Nature Research, 2021-12-09)[EN]Theropod behaviour and biodynamics are intriguing questions that paleontology has been trying to resolve for a long time. The lack of extant groups with similar bipedalism has made it hard to answer some of the questions ... -
Fe(III) Biomineralization in the Surface Microlayer of Acid Mine Waters Catalyzed by Neustonic Fe(II)-Oxidizing Microorganisms
(MDPI, 2023-04-01)The formation of thin mineral films or encrustations floating on the water surface of low-flow or stagnant zones of acid mine drainage (AMD)-affected streams is probably among the most exotic features that can be found in ... -
Garnet as Indicator of Pegmatite Evolution: The Case Study of Pegmatites from the Oxford Pegmatite Field (Maine, USA)
(MDPI, 2021-07-23)Almandine-spessartine garnets, from the Oxford County pegmatites and the Palermo No. 1 pegmatite, record significant compositional variations according to the degree of evolution of their hosting rock. Garnets from the ... -
Geochemical dataset of high-pressure acid migmatites from the Cabo Ortegal Complex (NW Spain)
(Elsevier, 2022-02)This brief note presents geochemical data from rock samples from the Cabo Ortegal Complex (NW Spain). The samples belong to acid lithologies within the mainly basic to intermediate granulite unit that have been poorly ... -
Geometric Morphometrics and Machine Learning Models Applied to the Study of Late Iron Age Cut Marks from Central Spain
(MDPI, 2023-03-21)Recently the incorporation of artificial intelligence has allowed the development of valuable methodological advances in taphonomy. Some studies have achieved great precision in identifying the carnivore that produced tooth ... -
Glaze characterization of the glazed pottery from the medieval workshop of Vega (Burgos, Spain)
(John Wiley & Sons, 2021-03-05)Sixteen glazes on medieval (14th–16th century AD) pottery fragments from Vega pottery workshop (Burgos, Spain) were characterized to investigate the production technology. To this end, Raman spectroscopy and scanning electron ... -
Glycerol amendment enhances biosulfidogenesis in acid mine drainage-affected areas: An incubation column experiment
(Frontiers Media, 2022-08)Microbial sulfate (SO4 (2-)) reduction in Acid Mine Drainage (AMD) environments can ameliorate the acidity and extreme metal concentrations by consumption of protons via the reduction of SO4 (2-) to hydrogen sulfide (H2S) ... -
IBERLID: A lead isotope database and tool for metal provenance and ore deposits research
(Elsevier, 2021-10)[EN] Although sometimes controversial, the use of Pb isotope data in geological research of ore deposits and metal provenance studies in archaeology has proved a useful tool for investigation of the relations between ore ... -
Interpretation of the Reflectance Spectra of Lithium (Li) Minerals and Pegmatites: A Case Study for Mineralogical and Lithological Identification in the Fregeneda-Almendra Area
(MDPI, 2021-09-15)Reflectance spectroscopy has been used to identify several deposit types. However, applications concerning lithium (Li)-pegmatites are still scarce. Reflectance spectroscopic studies complemented by microscopic and geochemical ... -
