Development and physical characteristics of the Irish shelf-edge Macnas Mounds, Porcupine Seabight, NE Atlantic
(2024)Modern cold-water corals (CWCs) occur in a wide range of water depths, with Desmophyllum pertusum being one of the most common species. Pleistocene, Holocene, and modern coral mound formation by living CWC reefs have ... -
Assessment of natural radioactivity and radon release potential of Silurian black shales
(2023)Many countries are developing a radon action plan to provide decision-makers with a reliable tool for reducing the harmful effects of radon exposure in dwellings and among the general public and, accordingly, to implement ... -
Applying machine learning to model radon using topsoil geochemistry
(2023)Radon is classified as a Class 1 carcinogen, being the leading cause of lung cancer in non-smokers. Understanding the prominent sources of radon helps to mitigate against the adverse effects of radon exposure. Considering ... -
Age of the oldest known Homo sapiens from eastern Africa
(2022)Efforts to date the oldest modern human fossils in eastern Africa, from Omo-Kibish and Herto in Ethiopia, have drawn on a variety of chronometric evidence, including 40Ar/39Ar ages of stratigraphically associated tuffs. ... -
Deep, ultra-hot-melting residues as cradles of mantle diamond
(2023)The ancient stable continents are up to 250 km deep, with roots extending into the diamond stability field. These cratons owe their mechanical strength to being cool and rigid, features inherited from extensive melt ... -
Uranium-lead geochronology applied to pyrope garnet with very low concentrations of uranium
(2023)We present U–Pb dates from peridotitic pyrope-rich garnet from four mantle xenoliths entrained in a kimberlite from Bultfontein, South Africa. Garnet dates magmatic emplacement due to the high mantle residence temperatures ... -
A study of natural radioactivity levels and radon/thoron release potential of bedrock and soil in southeastern ireland', International Journal of Environmental Research and Public Health
(2021)Radon (222Rn) and thoron (220Rn) account for almost two-thirds of the annual average radiation dose received by the Irish population. A detailed study of natural radioactivity levels and radon and thoron exhalation rates ... -
Application of airborne geophysical survey data in a logistic regression model to improve the predictive power of geogenic radon maps. A case study in Castleisland, county Kerry, Ireland
(2023)In this study, a novel methodology was investigated to improve the spatial resolution and predictive power of geogenic radon maps. The data inputs comprise indoor radon measurements and seven geogenic factors including ... -
Determining the impact of magma water contents on porphyry Cu fertility: constraints from hydrous and nominally anhydrous mineral analysis
(2023)Most large-scale porphyry-style mineralization is genetically associated with oxidized, sulfur-rich, and hydrous magmas, the sources of which were enriched in mantle-derived or juvenile crust−derived materials. Geochemical ... -
Editorial: Multidisciplinary Investigations for Determining the Structure and Dynamics of Active Volcanic Systems
(2022)Multidisciplinary investigations are widely considered by the scientific community to be the key strategy for understanding the interplay between magmatic processes and volcanic structures as a primary task for volcanological ... -
Wanted Dead or Alive: Skeletal Structure Alteration of Cold-Water Coral Desmophyllum pertusum (Lophelia pertusa) from Anthropogenic Stressors
(2023)Ocean acidification (OA) has provoked changes in the carbonate saturation state that may alter the formation and structural biomineralisation of calcium carbonate exoskeletons for marine organisms. Biomineral production ... -
Multiple fluorescence approaches to identify rapid changes in microbial indicators at karst springs
(2023)Karst springs are globally important for drinking water supply but are often also exceptionally vulnerable to contamination. Such springs usually exhibit strong variation in microbial water quality in sharp response to ... -
Metasomatism of the Kaapvaal Craton during Cretaceous intraplate magmatism revealed by combined zircon U-Pb isotope and trace element analysis
(2021)The origins of the mica-amphibole(K-richterite)-rutile-ilmenite-diopside (MARID) and the, presumably related, phlogopite-K-richterite-peridotite (PKP) mantle xenolith suites remain enigmatic. For instance, it is unclear ... -
Depth-dependent peridotite-melt interaction and the origin of variable silica in the cratonic mantle
(2021)Peridotites from the thick roots of Archaean cratons are known for their compositional diversity, whose origin remains debated. We report thermodynamic modelling results for reactions between peridotite and ascending mantle ... -
A Thermodynamic Model for the Subsolidus Evolution and Melting of Peridotite
(2021)We present a structural update to the thermodynamic model for calculating peridotite phase relations and melt compositions at 0·01 to 60 kbar and from 600 °C to the peridotite liquidus in the system K2O–Na2O–CaO–FeO–MgO– ... -
Lake Ohrid?s tephrochronological dataset reveals 1.36?Ma of Mediterranean explosive volcanic activity
(2021)Tephrochronology relies on the availability of the stratigraphical, geochemical and geochronological datasets of volcanic deposits, three preconditions which are both often only fragmentary accessible. This study presents ... -
Community established best practice recommendations for tephra studies?from collection through analysis
(2022)Tephra is a unique volcanic product with an unparalleled role in understanding past eruptions, long-term behavior of volcanoes, and the effects of volcanism on climate and the environment. Tephra deposits also provide ... -
No evidence for tephra in Greenland from the historic eruption of Vesuvius in 79?CE: implications for geochronology and paleoclimatology
(2022)Volcanic fallout in polar ice sheets provides important opportunities to date and correlate ice-core records as well as to investigate the environmental impacts of eruptions. Only the geochemical characterization of volcanic ... -
Geochronology and glass geochemistry of major pleistocene eruptions in the Main Ethiopian Rift: Towards a regional tephrostratigraphy
(2022)The Main Ethiopian Rift (MER) is renowned as a focus of investigations into human origins. It is also the site of many large volcanic calderas, whose eruptions have spanned the timeframe of speciation, cultural innovation, ... -
Eruption frequency and magnitude in a geothermally active continental rift: The Bora-Baricha-Tullu Moye volcanic complex, Main Ethiopian Rift
(2022)Many Quaternary silicic volcanoes in the Main Ethiopian Rift pose a potential risk due to the poorly known eruptive histories of the volcanoes in combination with a high population density. In this study we provide new ...
