    The BGS Rock Classification Scheme (RCS) is a comprehensive classification scheme for all types of rocks and unconsolidated sediments worldwide. It is intended to be used for classification of single rock samples and can be used without any knowledge of field relationships. It has been designed for use by people with a wide range of geological knowledge; from experienced professional geologists to technicians and drillers. It also allows names to be assigned according to the level of information about the sample. The system if hierarchical, ranging from very simple names such as igneous rock to highly detailed names such as mugearite, that can only be applied after chemical analysis. Rock names can consist of a root name e.g. granite and several qualifiers that impart more information e.g. grey-biotite-bearing granite. The classification scheme has been implemented as a hierarchical dictionary of codes for all rock types. The classification scheme is described in BGS Research Reports 99-02, 99-03, 99-06. The BGS Rock Classification Scheme was devised between 1993 and 1996 in response to a need from the Digital Map Production System project.

    Stored in Murchison House, this dataset (FAUNGRAPHLOG_ED) is the BGS UK (North) collection of paper graphic logs from boreholes and measured natural sections, particularly in the Carboniferous of Scotland and northern England. Some 18000 of these records include hand written macrofossil occurrences and assemblages from certain (often subsequently interpreted) stratigraphical levels in the borehole or section. There is at present no separate index (either analogue or digital) to FAUNGRAPHLOG_ED but a pathway to it is FOSSLOC, the index to the Survey Collection of fossils from UK (North).

    The BGS collection of downhole CCTV (Closed Circuit Television) recordings and backup tapes for worldwide SKYLAB satellite imagery. CCTV recordings carried out down boreholes, mainly drilled for water, were undertaken by BGS for specific commercial contracts in Great Britain, and may also have associated geophysical data. The collection started in 1997, and the present holdings are 138 videos, with infrequent additions. Video recordings on other topics may be added.

    Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:50 000 scale. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 2.58 million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by ice, water, wind and weathering. As such, the deposits are denoted by their BGS Lexicon name, which classifies them on the basis of mode of origin (lithogenesis) with names such as, 'glacial deposits', 'river terrace deposits' or 'blown sand'; or on the basis of their composition such as 'peat'. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The digital data includes attribution to identify each deposit type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volume 4). The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

    All type and figured calcareous microfossils and palynmorphs held in the BGS collections are registered using the prefix 'MPK'. To date MPK1 to 13400 have been used. Information includes name, locality, geological details and journal details.

    Hydrogeological maps of the UK at various scales. Hydrogeological maps of the UK provide information on major aquifers, including geological and lithological information, surface drainage systems and water quality issues. The 23 maps show information on surface water features, the three dimensional geometry of aquifers, groundwater levels, abstractions and quality including saline intrusion in varying amounts of detail. They range in scale from 1:625 000, for the national map of the hydrogeology of England and Wales, down to 1:25 000 for some of the smaller regional maps.

    This digital data set contains original files of seismic reflection survey sections. Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. These data are used for workstation-based interpretation. Some are kept as archive copies. There are approximately 50 tapes and 15 Exabyte cartridges. The data are mostly concentrated in areas prospective for coal, oil and gas.

    Corrected and smoothed and network adjusted ship gravity, magnetics and bathymetry data acquired by BGS as part of its Offshore Reconnaissance Mapping Programme. This programme was commenced in 1967, funded mainly by the Department of Energy.

    Microfossil samples submitted to the BGS biostratigraphy laboratory are currently registered using the prefix 'MPA'. Samples include rock, residues from sample preparations, and slides of mounted specimens. Rock, residues and slides from the same sample all bear the same unique identifying sample number. The numbers MPA 1 to 54400 have been used, but this grows steadily. There are currently 21 volumes of registered samples. The value added dataset comprises data for each sample held in the sample register, including collectors' symbols and numbers, 1:10k (or 6") OS quarter sheet, NGR, 1:50k (or 1") geological sheet, borehole name and depth (if relevant), locality, geological formation and report numbers. The value added dataset also includes identifications of specimens on each slide, which are listed on logging sheets and are held separately.

    Field notebooks,maps, field sheets etc for Regional gravity observations on the UK mainland, Northern Ireland, offshore islands, tidal estuaries and seabed. Most of the surveys were carried out by the BGS but the database includes data originally acquired by other organisations and subsequently given to the BGS to be managed as part of the national archive. Complete coverage of the UK mainland with a station density of 1-2 stations per square kilometre.
