    This layer of the map based index (GeoIndex) providex an index to 17,500 borehole rock samples (drillcore) from the Mineral Reconnaissance Programme (MRP) and related studies. The UK Government's Department of Trade and Industry (DTI) funded BGS to provide baseline information on areas prospective for the occurrence of metallic minerals in Great Britain. This programme, known as the MRP, ran continuously from 1973 to 1997 and covered particular locations across Great Britain. It was designed to stimulate private sector exploration and to encourage the development of Britain's indigenous mineral resources. Under the programme a number of boreholes were drilled to gather information.

    This layer of the map based index (GeoIndex) shows the location of drillcore, bulk specimens, unwashed cuttings and processed material from onshore boreholes drilled in UK by BGS, commercial and public bodies. The majority of borehole cores and samples are available for study and sub-sampling by bona fide academics and commercial companies. Commercial companies are charged for access; academics will need to complete an academic waiver form.

    This data was generated at the University of Kiel, Germany by Wolfgang Kuhnt, paid for by Dr Littler as part of her 2016 NERC Moratorium Award. The data comprises XRF-derived elemental abundances from two Holes (A and B) for International Ocean Discovery Program (IODP) Site U1448, spanning approximately the Pliocene period.

    Collection of drillcore, bulk samples, unwashed cuttings and processed material from onshore boreholes drilled in the UK by BGS, commercial and public bodies. Developed as part of the BGS responsibility to establish and maintain a National Borehole collection. Details of the collection are held on the 'Borehole Materials Database', and may be accessed over the internet from the BGS internet site.

    This layer of the Map based index (GeoIndex) shows the location of registered samples of drillcore and washed cuttings from onshore boreholes drilled in UK by BGS, commercial and public bodies, representing almost 10,000 boreholes. There is also a drillcore collection taken from onshore boreholes drilled in England and Wales by the BGS and commercial and public bodies.

    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 drilled at Dounreay, totalling 2,286 metres of drilling. Again, much of the drilling was to obtain continuous core. In most of the boreholes a suite of data acquisition techniques were used, including: continuous coring, geophysical wireline logging, hydraulic testing, sampling and analysis of groundwaters. Mineralogical data were acquired by detailed core observation, petrographic analysis, fluid inclusion analysis and stable and radiogenic isotope studies. Testing on samples from the rock cores was undertaken to determine petrological, mineralogical, hydrogeological, geophysical and geotechnical parameters. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.

    The borehole information pack from borehole GGC01, site 10 of the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This final data release pack from BGS contains geophysical (MSCL-S), Near Infrared (NIR) and X-ray Fluorescence (XRF; mineralogical and chemical) core scan and core-wireline depth integration data, in addition to sedimentology, discontinuity and engineering logs, core scan optical and X-ray images, composite and digital wireline logs, drillers' summary logs and prognosis, sample recovery information spreadsheets and daily drillers' borehole records that were contained within the now-superseded intermediate data release. The cored, seismic monitoring borehole was drilled between 19 November and 12 December 2018 to 199m producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. A range of fluid, water and core samples were taken during the drilling process. The borehole information pack- final release contains a range of logs on the core as well as images and scans of that core, these data were acquired in the first half of 2019 and late 2020/early 2021. The final data release for GGC01 includes: 1. UKGEOSGlasgow_GGC01_Final.zip file that includes the majority of the various data files, including files from the intermediate and initial data packs. 2. UKGEOSGlasgowGGC01_slabbedhighresimages.zip that contains the slabbed core optical images, 51GB in size. 3. Intermediate Borehole Information Pack - Part Two, high resolution whole core optical and radiographic images https://doi.org/10.5285/0b49f25b-a5d6-401c-98ff-397ad9ee9ed1 71GB in size, already released. Further details and model limitations can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/530762

    The dataset is a subset of the BGS borehole material database, created on August 1st 2015 covering only the Bowland-Hodder geological unit (as defined and mapped by Andrews et al., 2013). It shows all boreholes (name, location and registration details) for which BGS hold borehole material (drillcore, cuttings, samples and their depth ranges). This data will add value to existing NERC (Natural Environment Research Council) data by allowing a simple route for users to identify borehole material from the Bowland-Hodder interval.

    Due to differential loading of ice on Britain and Ireland the glacial isostatic adjustment (GIA) response and therefore sea-level record will vary with distance from the centre of the British Irish Ice Sheet. GIA models are tested against geological observations, however there is a paucity of observations below -10m depth and the lateglacial period when the BIIS retreated leading to a rapid response of both sea-level and GIA. The aim of the project was to use geophysical data, ground truthed by core material, to find evidence of lateglacial sea-level minima in the Irish and Celtic Sea to refine these GIA models. Cruise log and digital copies of the core information (location, water depth, core length) taken onboard the research cruise CE12008 on the RV Celtic Explorer. A GeoReseource 6m vibrocorer was used to collect sediment samples. Cores where taken at multiple sites and from southern and eastern Ireland: Bantry Bay, Dunmanus Bay, Waterford,Offshore County Louth and Dundalk Bay, offshore Isle of Man; offshore Wales: Cardingan Bay; and offshore Northern Ireland: Kilkeel and Dundrum Bay, Belfast Lough.

    The paper archives comprise a set of the factual and interpretative reports that document the investigations carried out by Nirex (Nuclear Industry Radioactive Waste Executive) and its contractors. In total there are in excess of 2,250 individual volumes. It is the availability of this paper archive of results and interpretation that makes the Nirex geological archives of rock cores and samples unique. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.
