Petrological, mineralogical and geochemical peculiarities of Archaean cratons
(2019)The most outstanding features of Archaean cratons are their extraordinary thickness and enduring longevity. Seismically, Archaean cratonic fragments are sharply-bounded deep roots of mechanically strong, cold lithospheric ... -
Petrology and dating of the Permian lamprophyres from the Malá Fatra Mts. (Western Carpathians, Slovakia)
(2018)Calc-alkaline lamprophyres are known from several localities in the Malá Fatra Mountains. They form dykes (0.5-3 m) of varying degree of alteration that have intruded the surrounding granitoid rocks which are often ... -
Physicochemical and Additive Controls on the Multistep Precipitation Pathway of Gypsum
(MDPI, 2017)Synchrotron-based small- and wide-angle X-ray scattering (SAXS/WAXS) was used to examine in situ the precipitation of gypsum (CaSO4·2H2O) from solution. We determined the role of (I) supersaturation, (II) temperature and ... -
Quantitative solid phase microextraction - Gas chromatography mass spectrometry analysis of the pesticides lindane, heptachlor and two heptachlor transformation products in groundwater
(2013)This paper describes the development and validation of a method for the determination of lindane, heptachlor and two heptachlor transformation products (exo- and endo-heptachlor epoxide) in groundwater. Samples were ... -
Radon Potential as a diagnostic tool for indoor radon hazard mapping
(2019)At over 56% of the annual effective dose, radon is the primary source of ionizing radiation exposure received by the Irish population. Although the average indoor radon concentration in Ireland has been reduced since ... -
Rapid radon potential classification using soil-gas radon measurements in the Cooley Peninsula, County Louth, Ireland
(2019)A rapid method for local-scale radon risk assessment using in situ radon soil-gas measurements and a national-scale soil permeability data set have been evaluated. We test and validate our approach in a case study on the ... -
Rare Earth Element Determination in Olivine by Laser Ablation-Quadrupole-ICP-MS: An Analytical Strategy and Applications
(2017)Olivine offers huge, largely untapped, potential for improving our understanding of magmatic and metasomatic processes. In particular, a wealth of information is contained in rare earth element (REE) mass fractions, which ... -
Re-Os geochronology of the Neoproterozoic - Cambrian Dalradian Supergroup of Scotland and Ireland: Implications for Neoproterozoic stratigraphy, glaciations and Re-Os systematics
(2011)New Re-Os geochronology for the Ballachulish Slate Formation of the Dalradian Supergroup, Scotland yields a depositional age of 659.6 ? 9.6 Ma. This age represents the first successful application of the Re-Os system to ... -
Reaction Pathways toward the Formation of Bastnäsite: Replacement of Calcite by Rare Earth Carbonates
(2021)The interaction of rare earth bearing (La, Nd, Dy) aqueous solutions with calcite crystals at ambient and hydrothermal conditions (25–220 °C) results in the solvent-mediated surface precipitation and subsequent pseudomorphic ... -
Revisiting the Y-3 tephrostratigraphic marker: a new diagnostic glass geochemistry, age estimate, and details on its climatostratigraphical context
(2015)The ‘Y-3’ tephra is a crucial stratigraphic marker within the central Mediterranean region that falls close to the Marine Isotope Stage 3/2 transition and a cooling event proposed as a correlative of the North Atlantic ...
