  • In 2011 the British Geological Survey (BGS) decided to begin the assembly of a National Geological Model (NGM) from its existing and on-going geological framework models , comprising integrated national crustal, bedrock and Quaternary models. The bedrock component is the most advanced of these themes and comprises both the calculated models and a complementary network of cross-sections that provide a fence diagram for the bedrock geology of Great Britain. This fence diagram, the GB3D_v2014 dataset is available in a variety of formats from the BGS website www.bgs.ac.uk as free downloads, it supercedes the earlier 2012 version. The model complements the existing 1:625 000 scale mapsheets published by BGS utilising the same colour schema and geological classification. The component cross-sections extend to depths between 1.5 and 6 km; they have an aggregate length of over 25,000 km, and they are snapped together at their intersections to ensure total consistency. The sections are based on the existing BGS geological framework models where they cut through them together and incorporate around 300 deep stratigraphic boreholes across England and Wales. The sections also take account of the vast wealth of published data on the subsurface structure of Britain both from BGS and in the scientific literature. Much of this is in the form of cross-sections, contour maps of surfaces, and thicknesses (isopachs). The fence diagram has been built in the Geological Surveying and Investigation in 3D (GSI3D) software. It is envisaged that this dataset will form a useful educational resource for geoscience students and the general public, and also provide the bedrock geology context and structure for regional and catchment scale studies. The fence diagram has been built in stages between 2009-14 using funding from the BGS National Capability Programme the Environment Agency of England and Wales, and the Nuclear Decommissioning Authority. Some 16 expert regional geologists compiled the sections.

  • The data comprises GIS layers representing the permeability of artificial deposits for Great Britain. The permeability data has been derived from DiGMap-GB (Digital Geological Map Data of Great Britain), and therefore reflects the scale of DiGMap-GB. For the majority of the Great Britain, the scale is 1:50,000. The data is updated annually, or after a major new release of DiGMap-GB. The permeability data describes the fresh water flow through these deposits and the ability of a lithostratigraphical unit to transmit water. Maximum and minimum permeability indices are given for each geological unit to indicate the range in permeability likely to be encountered and the predominant flow mechanism (fracture or intergranular). Neither of the assigned values takes into account the thickness of either the unsaturated or saturated part of the lithostratigraphical unit. The data can be used freely internally, but is licensed for commercial use. It is best displayed using a desktop GIS, and is available in vector format as ESRI shapefiles and MapInfo TAB files.

  • A significant part of this data collection is geophysical survey data in digital form, being mainly instrumental recordings made during fieldwork. Derived data created during the subsequent processing and interpretation of the field data is described in 'Nirex Magnetic Tape Archives - Processed Data'. These data were originally stored on a variety of media. With the overall aim of delivering an efficient and effective archive service, the data have been consolidated onto DLT cartridges. Some related data, which were either analogue, on obscure media or in unknown formats have been retained in their original form. British Geological Survey maintains a full catalogue of the data, as an Access database.The data sets that comprise the magnetic archive are the following: Seismic surveys: marine, land and transition zone; field, navigation, statiatcs; Geophysical wireline logging of boreholes: routine wireline logging of investigation boreholes (gamma-ray, sonic, porosity, etc.); velocity surveys; dipmeter surveys;vertical seismic profiling; borehole televiewer (BHTV) surveys; formation microscanner (FMS) surveys; Ground surveys: magnetic; gravity; radiometric; thermal imaging; photographic imaging; in-flight videos. 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 Estimated Ambient Background Soil Chemistry England and Wales dataset indicates the estimated geometric mean topsoil Arsenic(As), Cadmium (Cd), Cr (Chromium), Nickel (Ni) and Lead (Pb) concentrations (mg kg-1). The soil chemistry data is based on GBASE (Geochemical Baseline Survey of the Environment) soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element (PHE) concentrations. This dataset covers England and Wales but data is available for the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment.

  • A core scanning dataset from the BHA-101 drill core that was drilled onshore at the Ince Marshes site near the village of Elton, Cheshire, UK as part of the UK Geoenergy Observatories (UKGEOS) Cheshire ground investigation funded by UKRI/NERC. This core scanning dataset pack contains high-resolution optical and radiographic images, X-ray fluorescence (XRF) and physical property downcore point measurements on core from 71.12 m to 121.1 m (Sherwood Sandstone Group) obtained at the Core Scanning Facility (CSF) at the British Geological Survey (BGS).

  • This dataset of paper records holds details of analysis of all the sample batches (from both internal and external customers) analysed by the Analytical Geochemistry Laboratory of the BGS since June 1996. It was installed to underpin the UKAS (United Kingdom Accreditation Service) accreditation of the geochemistry laboratories at Keyworth, which was awarded in August 1999. There is a file for each batch of samples submitted for analysis. The file documents the progress of the samples through the laboratories, including sample registration, sample processing, raw data from analytical instruments and the data reported to the client. The records are archived to provide supporting evidence for any query regarding geochemical data provided by the laboratories.

  • Revised full proposal for scientific drilling (852-CPP2) 'GlaciStore: Understanding Pleistocene glaciation and basin processes and their impact on fluid migration pathways (North Sea)', submitted to Integrated Ocean Discovery Programme (IODP) April 2016. The proponent 'GlaciStore' consortium comprises research and industry organisations from the UK, Norway, USA and Canada. The full proposal describes the relationship of the proposed research with the IODP science plan, sets the regional background and describes and illustrates three scientific objectives. The objectives are to: establish a high-resolution depositional and chronological framework defining multiple cycles of glacial advance and retreat over the last 2.6 Ma by investigating the strata preserved in the centre of the NSB by scientific drilling, sampling and detailed analysis; investigate how the temporal variations in depositional environment and geochemistry of the different stratigraphic units have affected the pore fluids (dissolved gases, salts and isotopes) and the microbial community; determine the measurable impact on geomechanical properties of strata (porosity, rock stiffness, in-situ stresses, pore pressure, fractures) caused by cycles of glacial loading and unloading. The drilling and sampling strategy, standard drilling and logging operations and the specialist measurements expected to be taken are described. Related initiatives and wider context of the proposed research also the initial and planned strategy for support from industry and government are outlined. The lead submitter, on behalf to the GlaciStore consortium is Heather Stewart, British Geological Survey (BGS).The 32 proponents from the UK and Norway (BGS, Institute for Energy Technology, Lundin Norway AS, Memorial University of Newfoundland, SINTEF Energy Research, Statoil ASA, University of Bergen, University of Edinburgh University of Oslo, University of Texas at Austin and University of Ottowa) and their expertise are listed and detailed. Site forms for each of the 13 proposed drilling sites are included.The full proposal is a pdf format file. This is restricted to the proponents for publication and to progress to a revised full proposal accepted for drilling by IODP. UKCCSRC Grant UKCCSRC-C1-30.

  • This dataset has now been superseded, please see the Estimated Ambient Background Soil Chemistry England and Wales dataset. This dataset indicates the estimated topsoil Arsenic(As), Cadmium (Cd), Cr (Chromium), Nickel (Ni) and Lead (Pb) concentrations (mg kg-1) derived by spatial interpolation of the point source urban soil PHE (potentially harmful elements) data. Urban soil geochemical data generally have large positive skewness coefficients so were transformed by taking natural logarithms. To overcome the bias associated with traditional measures of location (mean) and scale (standard deviation) for log-normal data, the inverse distance weighted (IDW) mean and standard deviation of log transformed element concentrations were used for mapping the spatial variation in As, Cd, Cr, Ni and Pb concentrations. The soil chemistry data is based on GBASE (Geochemical Baseline Survey of the Environment) soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element(PHE) concentrations. This dataset covers England and Wales but data is available for the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment.

  • These are OS 1:25000 paper maps (approximately 1400) upon which the Ministry of Housing and Local Government (currently Department for Communities and Local Government (CLG)) recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). Priority was placed on areas that were given rise to then current casework issues thus, at the time when the maintenance of the maps ended some authority information had been updated recently but other areas had not been visited for many years. Therefore, the variable completeness of the data should be kept in mind when the material is being used. Both the maps and the card index have been used to create the digital mineral planning permissions polygons (see metadata for MHLG Planning Permission Polygons). Polygons for worked ground have not been captured.
