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 ... -
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 ... -
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 ... -
Rift flank uplift at the Gulf of California: No requirement for asthenospheric upwelling
(2014)Continental rifts are commonly flanked by zones of high elevation, but the cause of uplift remains controversial. Proposed uplift mechanisms include active and induced asthenospheric upwelling, and isostatically driven ... -
Silicon and chromium stable isotopic systematics during basalt weathering and lateritisation: A comparison of variably weathered basalt profiles in the Deccan Traps, India
(2018)Global biomass production is fundamentally affected by the hydrological cycling of elements at the Earth’s surface. Continental weathering processes are the major source for most bio-essential elements in marine environments ... -
Simplifying and improving the extraction of nitrate from freshwater for stable isotope analyses
(Royal Society of Chemistry, 2011)Determining the isotopic composition of nitrate (NO3 ) in water can prove useful to identify NO3 sources and to understand its dynamics in aquatic systems. Among the procedures available, the `ion-exchange resin method? ... -
Temperature time evolution of the Assynt Terrane of the Lewisian Gneiss Complex of Northwest Scotland from zircon U-Pb dating and Ti thermometry
(2015)The Lewisian Gneiss Complex of Northwest Scotland is a classic Precambrian basement gneiss complex. The Lewisian is divided into a number of terranes on the basis of structural, metamorphic and geochronological evidence. ... -
A Toba-scale eruption in the Early Miocene: the Semilir eruption, East Java, Indonesia
(2011)The Indonesian archipelago is well known for volcanic activity and has been the location of three catastrophic eruptions in the last million years: Krakatau, Tambora and Toba. However, there are no reports of large magnitude ... -
A U-Pb age for the Late Caledonian Sperrin Mountains minor intrusions suite in the north of Ireland: timing of slab break-off in the Grampian terrane and the significance of deep-seated, crustal lineaments
(2013)An intrusion of trachy-andesite, representative of a newly discovered suite of high-K–Ba–Sr, calc-alkaline minor intrusions (termed herein the Sperrin Mountains suite), hosted within the Grampian terrane in the north of ... -
U-Pb and Th-Pb dating of apatite by LA-ICPMS
(2011)Apatite is a common U- and Th-bearing accessory mineral in igneous and metamorphic rocks, and a minor but widespread detrital component in clastic sedimentary rocks. U-Pb and Th-Pb dating of apatite has potential application ... -
U-Pb LA-ICPMS dating using accessory mineral standards with variable common Pb
(2014)Precise and accurate U?Pb LA-ICPMS dating of many U-bearing accessory minerals (e.g. apatite, allanite, titanite and rutile) is often compromised by common Pb. LA-ICPMS dating of these U-bearing accessory phases typically ... -
U-Pb zircon ages for Yarlung Tsangpo suture zone ophiolites, southwestern Tibet and their tectonic implications
(2015)Ophiolite complexes preserved along the Yarlung Tsangpo suture zone (YTSZ) and obducted onto the northern continental margin of India in southern Tibet represent the remnants of the once extensive Permian–Mesozoic Neo-Tethyan ...
