The effects of land drainage on groundwater resources in karstic areas of Ireland
(Geological Publishing House, Beijing, China, 1988)The impact of land drainage on groundwater resources is particularly acute in karst areas because of the unique characteristics of karstic aquifers. Arterial drainage of karst lowlands in Ireland, involving the construction ... -
Unsaturated zone travel time to groundwater on a vulnerable site
(2005)A bromide (Br) tracing experiment was conducted to ascertain unsaturated zone travel time to groundwater on a site with a karstified limestone aquifer overlain by a thin free-draining overburden. Br tracer was applied to ... -
The impact of agricultural management practices on nutrient losses to water: data on the effects of soil drainage characteristics
(2005)Against the background of increasing nutrient concentrations in Irish water bodies, this study set out to gain information on the potential of agricultural grassland to lose nutrients to water. Overland flow, flow from ... -
Co-existing fluid and silicate inclusions in mantle diamond
(2006)We document the compositions of co-existing silicate macro-inclusions and fluid micro-inclusions in the fibrous coats of eight coated diamonds from the Panda kimberlite (Canada). The mineral inclusions in the diamond coats ... -
Crystal structure of dicalcium sodium monohydrogen diarsenate hexahydrate, Ca2Na[HAsO4][AsO4] · 6H2O
(De Gruyter, 2006)As2Ca2H13NaO14, triclinic, P1 (no. 2), a = 6.680(5) Å, b = 8.223(4) Å, c = 12.537(3) Å, = 73.46(5)°, = 78.89(4)°, = 87.47(5)°, V = 647.7 Å3 , Z = 2, Rgt(F) = 0.062, wRref(F2 ) = 0.197, T = 293 K. Source of ... -
Quartz-bearing C-O-H fluid inclusions diamond: Retracing the pressure-temperature path in the mantle using calibrated high temperature IR spectroscopy
(2007)Infrared spectra of C–O–H micro-inclusions were collected from a micro-inclusion bearing diamond during step-heating and freezing experiments to examine fluid speciation as a function of pressure and temperature. The ... -
Variations in travel time for N loading to groundwaters in four case studies in Ireland: Implications for policy makers and regulators
(2009)Mitigation measures to protect waterbodies must be implemented by 2012 to meet the requirements of the EU Water Framework Directive. The efficacy of these measures will be assessed in 2015. Whilst diffuse N pathways between ... -
Hidden Archaean and Palaeoproterozoic crust in NW Ireland? Evidence from zircon Hf isotopic data from granitoid intrusions
(2009)The presence of major crystalline basement provinces at depth in NW Ireland is inferred from in situ Hf isotope analysis of zircons from granitoid rocks that cut structurally overlying metasedimentary rocks. Granitoids in ... -
Early mafic magmatism and crustal anatexis on the Isle of Rum: evidence from the Am M?m intrusion breccia
(2009)The Rum Igneous Centre comprises two early marginal felsic complexes (the Northern Marginal Zone and the Southern Mountains Zone), along with the later central ultrabasic?basic layered intrusions. These marginal complexes ... -
The correlation potential of magnetic susceptibility and outcrop gamma-ray logs at Tournaisian-Viséan boundary sections in western Europe.
(2010)We have measured five deep-water carbonate and carbonate-siliciclastic sections at the Tournaisian-Viséan (Tn/V) boundary in western Europe, using petrophysical outcrop logging techniques (gamma-ray spectrometry /GRS/ and ... -
The North Pennine batholith (Weardale Granite) of northern England new data on its age and form
(2010)A three-dimensional gravity model of the North Pennine batholith is interpreted to indicate that it comprises five contiguous steep-sided plutons. The North Pennine batholith was previously referred to as the Weardale ... -
Basic volcanism contemporaneous with the Sturtian glacial episode in NE Scotland
(2010)The Dalradian Supergroup contains three distinct glacigenic units, formerly termed `Boulder Beds?, which are correlated with widespread Neoproterozoic glaciations. The oldest and thickest unit, the Port Askaig Formation, ... -
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 ... -
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? ...
