    The UK Onshore Geophysical Library was established in 1994 in conjunction with the Department of Trade and Industry (DTI) and the UK Onshore Operators Group (UKOOG). The Library manages the archive and official release of seismic data recorded over landward areas of the UK. By agreement with the DTI and HMSO, the Library operates as a registered charity, funded by revenues raised from data sales and donations, with the long term objective of bringing all available UK onshore digital seismic data into secure archival storage, whilst providing efficient access to all interested parties. BGS has access to the data at cost of copying only for science budget work. Data index on the BGS Geoscience Data Index.

    These maps provide an overview, at the national scale, of the spatial relationships between principal aquifers and some of the major shale and clay units in England and Wales. The data comprises a series of occurrence maps shows the distribution of rock units that form the principal aquifers and some major shale and clay units in England and Wales. In addition, a series of separation maps show the vertical separation between pairs of shales or clays and overlying aquifers. If shale gas resources are to be developed in the UK, the implications for groundwater will need to be considered as part of any risk assessment. A step in such an assessment will be to understand and quantify the spatial relationships between the potential shale gas source rocks (including both shales and some clay units) and overlying aquifers. The datasets used to produce the aquifer maps, the shale and clay occurrence maps and the separation maps are available to download for your own use. As with other BGS data sets available for download, this will enable you to work offline to develop your own systems and methodologies using BGS data. The data used to produce the aquifer, shale and clay maps are available below as ESRI GIS and KML files.

    Coal resource maps for the whole of the UK have been produced by the British Geological Survey as a result of joint work with Department of Trade and Industry and the Coal Authority. The Coal Resources Map is a Map of Britain depicting the spatial extent of the principal coal resources. The map shows the areas where coal and lignite are present at the surface and also where coal is buried at depth beneath younger rocks. The maps are intended to be used for resource development, energy policy, strategic planning, land-use planning, the indication of hazard in mined areas, environment assessment and as a teaching aid. In addition to a general map of coal resources for Britain data also exists for the six inset maps: Scotland; North-East; North-West; East Pennines; Lancashire, North Wales and the West Midlands; South Wales, Forest of Dean and Bristol. Available as a paper map, flat or folded, from BGS Sales or as a pdf on a CD if requested.

    Two geochemical surveys were undertaken in the Solomon Islands between 1976 and 1983 as part of a combined geological mapping and mineral exploration project. The survey of Choiseul and the Shortland Islands was carried out between 1976 and 1979 by the Institute of Geological Sciences (now the British Geological Survey) with support from staff of the Geology Division of the Ministry of Land, Energy and Natural Resources, Solomon Islands. The project produced 12 geological maps at 1:50,000 scale as well as a series of unpublished reports. The survey of the New Georgia Group of islands was undertaken between 1979 and 1983. The project produced 7 geological maps at a scale of 1:100,000 and a regional map of the entire island group at a scale of 1:250,000. A series of multielement geochemical anomaly maps were produced at a scale of 1:100,000 to accompany each of the published geological maps. Master copies of these are held at the Geological Survey in Honiara. Full descriptions of the methods used are described in the margins of the anomaly maps. A total of 8848 stream sediment samples were collected from Choiseul and 7441 from the New Georgia Group, resulting in an average sampling density for the two areas of 2.68 samples per km2 and 1.47 samples per km2 respectively. Sampling in the Shortland Islands was confined to the larger islands, 187 were collected from the Fauro Island group, 148 from Alu and 69 from Mono. The samples were dry sieved and the fraction passing -80 mesh B.S. (177 microns) was analysed. A hot concentrated nitric acid digestion was used prior to analysis by atomic absorbtion spectrophotometry (AAS) for Co, Cu, Pb, Zn, Ni, Ag, and Mn. Samples from the vicinity of the Siruka Ultramafic Complex were determined for Cr by AAS after digestion by a bisulphate fusion technique. Raw data can be obtained from the Geology Division, Ministry of Mines and Energy, PO Box G37, Honiara, Solomon Islands.

    The map shows the localities of significant fossil samples, either collected by BGS Staff, or donated by individuals and institutions. The BGS fossil collections contain over 2 million specimens, including a sizeable quantity of type, figured and cited material. Since a small number of fossil locations are confidential, you are unable to view this dataset at large scales. However, if you send a data enquiry, such information may be made available. Enquiries are normally free, but a charge may be levied depending upon the time taken; users will be notified in advance. Material is available for inspection on application by e-mail. Specimens are sometimes available for loan to bona fide academics.

    This mineral resource data was produced as part of the Mineral Resource Map of Northern Ireland via a commission from the Northern Ireland Department of the Environment. The work resulted in a series of 21 data layers which were used to generate a series of six digitally generated maps. This work was completed in 2012 with one map for each of the six counties (including county boroughs) of Northern Ireland at a scale of 1:100 000. This data and the accompanying maps are intended to assist strategic decision making in respect of mineral extraction and the protection of important mineral resources against sterilisation. They bring together a wide range of information, much of which is scattered and not always available in a convenient form. The data has been produced by the collation and interpretation of mineral resource data principally held by the Geological Survey of Northern Ireland and was funded via a commission from the Northern Ireland Department of the Environment. These layers display the spatial data of the mineral resources of Northern Ireland. There are a series of layers which consist of: Bedrock: Clay, Coal & Lignite, Coal – lignite proven, Conglomerate, Dolomite, Igneous and meta-igneous rock, Limestone, a 100m buffer layer on the Ulster White Limestone, Meta-sedimentary rocks, Perlite, Salt, sandstone and Silica Sand. Superficial (unconsolidated recent sediments) : Sand & gravel and Peat. The data except for the salt and proven lignite resource layers was derived from the 1:50 00 and 1:250 000 scale DigMap NI dataset. A user guide 'The Mineral Resources of Northern Ireland digital dataset (version 1)' OR/12/039 describing the creation and use of the data is available. A companion set of data with the internal boundaries retained is also available.

    This layer of the Map based index (GeoIndex) shows the location of records of boreholes, shafts and wells from all forms of drilling and site investigation work. Some 850,000 records dating back over 200 years and ranging from one to several thousand metres deep. Currently some 50,000 new records are being added to the collection each year. The dataset available via the GeoIndex is a snapshot, taken at a particular date, of the Single Onshore Borehole Index. Although the GeoIndex is updated at regular intervals more information may be available than is shown.

    The dataset describes the potential of bedrock aquifers across Scotland to sustain various levels of borehole water supply, and the dominant groundwater flow type in each aquifer. There are five aquifer productivity classes: very high, high, moderate, low and very low, and three groundwater flow categories: significant intergranular flow; mixed fracture/intergranular flow; and fracture flow. The dataset is a tool to indicate the location and productivity of bedrock aquifers across Scotland. It may have several uses, including in policy analysis and development; to prioritise aquifer and site investigations; to inform planning decisions; and to improve awareness of groundwater in general. The complexity and heterogeneity of geological formations means that the dataset is only a guide. It is designed to be used at a scale of 1:100,000, and not to assess aquifer conditions at a single point. Latest version: Bedrock aquifer productivity Scotland version 2
