    The map show the broad distribution of the industrial, including construction, mineral resources of Britain and the main sites where these are worked. Over extensive areas bedrock is covered by superficial deposits, including economically important sand and gravel resources. These superficial deposits are not shown on the map. Resources have been defined by dominant lithology (rock type). The map is a synthesis of the mineral resources and mineral working data held by the BGS in 1996. The published (paper) map has not been superseded however the digital mineral resources and mineral workings data has since been superseded. The map is logically consistent throughout.

    Collection of individually registered specimens and cuttings from onshore boreholes drilled in England and Wales by BGS, commercial and public bodies since the establishment of BGS in 1835. The collection has been developed as part of the BGS responsibility to establish and maintain a National Borehole Collection. The collection is updated on a daily basis by the addition of new data and by the modification of existing data. The collection contains all registered borehole samples for England and Wales, Scottish borehole samples are excluded. Details of the collection are held on the 'Borehole Materials Database', and may be accessed over the internet from the BGS web site.

    The Borehole Geology database holds downhole lithological / lithostratigraphical data (with unit-bound lithological properties where appropriate) for boreholes identified within the Single Onshore Borehole Index (SOBI), which covers onshore and nearshore Great Britain. The database can store multiple interpretations for each borehole and properties assigned to each coded lithological unit. Available borehole geology properties include porosity, Munsell colour, grainsize, water struck, etc, and other valid property-types can be included when/if required.

    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.

    The M2M Thematic Programme funded 17 scientific investigation projects leading to more unified physical understanding of fluid flow distributions in heterogeneous rock. The programme focused on developing an understanding of the relationships between measured and modelled subsurface fluid flows spanning the range of spatial and temporal scales relevant to fluid resource management. The programme was motivated by the growing recognition that assumptions of uniformity at certain scales are inadequate for extrapolating fluid behaviour both in time and space. Research spanning a wide spectrum of observation and simulation scales was undertaken by the programme which can be divided into four themes: (1) understanding the natural processes which lead to scaling relationships between size and magnitude of rock and flow heterogeneity; (2) quantification of essential fluid flow properties and their spatial pattern from measurements;(3) identification of appropriate statistical models and scaling laws describing rock property heterogeneity and fluid-rock interactions in geological media;(4) understanding the relationships between rock property distributions and flow model parameter distributions.

    This dataset contains parametric data (epicentre, magnitude, depth, etc) for over one million earthquakes worldwide. The dataset has been compiled gradually over a period of thirty years from original third-party catalogues, and parameters have not been revised by BGS, although erroneous entries have been flagged where found. The dataset is kept in two versions: the complete "master" version, in which all entries for any single earthquake from contributing catalogue are preserved, and the "pruned" version, in which each earthquake is represented by a single entry, selected from the contributing sources according to a hierarchy of preferences. The pruned version, which is intended to be free from duplicate entries for the same event, provides a starting point for studies of seismicity and seismic hazard anywhere in the world.

    Recordings of earthquakes and other signals (such as quarry blasts, explosions, sonic booms and collapses) made by a network of seismometers and similar sensors across the UK. Recordings start in 1977 (with a few events recorded before this) and continue to the present day. Data is used for monitoring of seismic activity, studies of seismic hazard and scientific study of the Earth's interior. Data is freely available on request. Some data can be retrieved from the BGS AutoDRM (Automatic Data Request Manager) service. Time series data recorded by UK seismic networks.

    Paper records and photos used to create the Nottingham Caves digital register and maps. Includes archival material of the caves known to BGS, around northern and central Nottingham. Data mainly captured in 1989, infrequent since then approximately 1 per year.

    Three volumes of SAM samples (SAM1-SAM4789) exist. They represent the work of FW Anderson in the 1950s and 1960s. All samples were re-registered into other datasets. They are predominantly from the Cretaceous and Tertiary. Sample number, fossil type, locality and geological details are given, including borehole name and depth where appropriate.
