As an integral part of the investigations carried out at Sellafield, and to a lesser extent for the Dounreay boreholes, the cores from the boreholes were systematically examined by geologists and samples selected for detailed petrographic analysis. Thin sections were prepared from many of these samples. Some of the samples were then prepared for analysis using X-ray fluorescence, X-ray diffraction or scanning electron microscopy. Samples containing fluid inclusions were prepared as doubly polished fluid in...

A collection of reference drawings relating to investigations carried out by Nirex, during the period from 1989 to 1997. The drawings summarise the status of the geological investigation at Sellafield and include borehole locations, geology (surface, structure, sections etc) and geophysics (seismic, airborne, etc). Sites near Sellafield, in Cumbria, and Dounreay, in Caithness. The Nirex (Nuclear Industry Radioactive Waste Executive) geological archive was transferred to the British Geological Survey during...

During the period from 1989 to 1997, Nirex undertook extensive geological investigations at sites near Sellafield, in Cumbria, and Dounreay, in Caithness, to examine whether or not they were suitable locations for a deep repository for radioactive waste. At Sellafield, thirty deep boreholes, and a further thirty-five shallow boreholes, were drilled. The majority of the deep boreholes were drilled to obtain continuous core and some 18.7km of rock core arose from the investigations. Two deep boreholes were d...

Concentrations of gaseous and aqueous fixed nitrogen products and isotopic measurements of aqueous nitrite and nitrate in spark discharge experiments. Spark experiments were conducted at the University of St Andrews in the St Andrews Isotope Geochemistry Lab (StAIG) between November 2020 and February 2022. Analysis of gaseous products was carried out with a quadrupole mass spectrometer (Hiden Analytical ExQ Quantitative Gas Analyser) in St Andrews. Measurement of concentrations of aqueous nitrite and nitra...

This dataset contains the nitrogen, oxygen, and lithophile element geochemistry of whole rock, and distribution coefficients, and stable isotope fractionation factors for biotite, orthoclase, and plagioclase mineral separates from the Loch Doon Zoned Pluton, Scotland. The samples were collected from the northern limb of the Loch Doon pluton and are petrologically classified as are granodiorites and granites which show geochemical evidence for being a cogenetic zoned pluton. The data were collected over a t...

This dataset consists of a spreadsheet of data and a series of photographs. A set of natural phlogopite crystals were exposed to varying partial pressures of a He-Ne-Ar gas mixture at 930-1030°C for 20-161 hours to investigate the solubility of these gases in phlogopite. The experiments and analyses were carried out in 2013 and 2014. The experiments were carried out in piston cylinder apparatus at Brown University, USA by Dr Colin Jackson and the gas concentrations measured at the Open University, UK, ...
