The data shows superficial polygons, bedrock polygons and fault linear geological information, sourced from published Geological Survey of Northern Ireland 1:250 000 scale maps - superficial (Quaternary 1991) and bedrock (Solid 1997). Full Northern Ireland coverage is available (Bedrock extends west into RI). The data is available in vector format. BGS licensing terms and conditions apply to external use of the data.
This data layer is the BGS contribution to the OneGeology project, providing UK onshore geological data at 1:625 000 scale and UK continental shelf seabed sediment data at 1:1 million scale. This map data is collected as part of an ongoing BGS project: Digital Geological Map of Great Britain (DiGMapGB). This layer is the seabed sediment data layer.
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.
Water samples have predominantly been collected by the G-BASE (Geochemical Baseline Survey of the Environment) project at an average sampling density of one sample per 1.5 km square. Samples have been collected from approximately 85% of Great Britain but it is only from Wales and Humber-Trent southwards that a wide range of analytes have been determined. Currently G-BASE stream water samples collected from high order streams are determined by ICP-AES for 27 elements - Sr, Cd, Ba, Si, Mn, Fe, P, S (as SO42-), B, Mg, V, Na, Mo, Al, Be, Ca, Zn, Cu, Pb, Li, Zr, Co, Ni, Y, La, K and Cr; and by quadrupole ICP-MS for 24 trace elements - Li, Be, Al, V, Cr, Co, Ni, Cu, As, Rb, Y, Zr, Mo, Ag, Cd, Sn, Sb, Ba, La, Ce, Tl, Pb, Th and U. Automated colorimetric methods are used to determine Cl and NO3- and ion selective electrode is used to determine F. Waters are also analysed for non-purgeable organic carbon (NPOC) to determine dissolved organic carbon content. All samples have routinely been analysed for pH, conductivity and bicarbonate. Much of the UK coverage also includes uranium and fluoride analyses.
NIGL (NERC Isotope Geosciences Laboratories) is a comprehensive stable and radiogenic isotope laboratory facility that undertakes environmental, life, archaeological and earth science research, and educates and trains PhD students, in a collaborative research environment. This dataset contains a complete listing of projects undertaken by NIGL since its formation in 1987. It includes projects approved by the NERC Isotope Geoscience Facilities Steering Committee, projects with BGS, BAS and other NERC institutes, and commercial work.
This national digital GIS product produced by the British Geological Survey indicates the susceptibility of corroded underground ferrous (iron) assets (e.g. pipes) to failure, as a result of ground instability. It is largely derived from the digital geological map and expert knowledge. The GIS dataset contains eight fields. The first field is a summary map that gives an overview of where corroded ferrous assets may fail. The other seven fields indicate the properties of the ground with respect to corrosivity and hazards associated with soluble rocks, landslides, compressible ground, collapsible ground, swelling clays and running sands. The data is useful to asset managers in water companies, local authorities and utility companies who would like to understand where underground ferrous assets are susceptible to failure as a result of ground conditions.
This layer of the map based index (GeoIndex) shows the locations of known mines, mineral showings and localities, including sites where minerals of economic interest have been identified in panned concentrates. The information for the index is taken from the Mineral Occurrence Database. The Mineral Occurrence Database holds information on mineral occurrences in the UK including locations of known mines, deposits, prospects and mineral showings, including sites where minerals of potential economic interest have been identified in panned concentrates. Data is normally taken from published sources or from internal BGS records, such as field sheets, rock and stream sediment collection cards. Data compilation started ca. 1994 and the database currently holds about 13 000 records, but details of many more old workings and occurrences remain to be added.
The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to show running sand behaviour under the action of flowing water, a characteristic usually of saturated sand and silt grade material. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.
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.
NIGL (NERC Isotope Geosciences Laboratories) is a comprehensive stable and radiogenic isotope laboratory facility that undertakes environmental, life, archaeological and earth science research, and educates and trains PhD students, in a collaborative research environment. This dataset contains a complete record of publications and scientific reports involving NIGL staff, dating from the formation of the group in 1987. The published research is not geographically restricted.
