Foreign sliced rock collection

The foreign sliced rock or 'F' collection consists of about 10, 000 specimens and thin sections, cited by their 'F' numbers. These include material archived from recent overseas projects and much collected during the late 19th or early 20th Century from regions within what was then the British Empire. It also includes 'exotic' materials donated to the Survey in its earlier years. Its coverage varies, although there is a predominance of African material. It is indexed on paper registers, and approximately 20% has been input onto 'Britrocks'.

Groundwater Level Archive

Database of water levels in selected observation boreholes: daily, weekly or monthly measurements. Consistent set of boreholes in catchments relatively undisturbed by pumping distributed across most significant aquifer units in the UK. Most sites have more than 30 years of data, and some sites have considerably longer time series. The dataset represents only 5% of active groundwater monitoring networks run by UK measuring agencies. BGS holds other, historical, groundwater level data, including one off measurements and time series.

BGS Geology 250k version 4

Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the dataset is 1:250 000, providing a generalised geology. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Data are supplied as two themes: bedrock and linear features (faults). Superficial, mass movement and artificial themes are not available onshore at this scale. Bedrock geology describes the main mass of solid rocks forming the Earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. Geological names are based on the lithostratigraphic or lithodemic hierarchy. This means rock bodies are arranged into units based on rock type and geological time of formation. Where rock types do not fit into the lithostratigraphic scheme, for example intrusive rocks or deformed rocks subjected to heat and pressure, resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. Data identifying linear features (shown as lines) represent geological faults at the ground or bedrock surface (beneath superficial deposits). Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the Earth's crust (tectonic forces). 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.

Mining hazard (not including coal) in Great Britain

The dataset indicates the potential for hazard in Great Britain as a result of mineral extraction. It excludes areas of Coal mining as these are covered by the Coal Authority. It is based on a simple A-E rating scale indicating the increasing likelihood of an underground mining hazard. The data was created using expert knowledge, detailed literature searches, local knowledge and a series of rule based geological constraints applied to the DigMapGB50k (Digital Geological Map of Great Britain) data.

National Superficial Deposits Thickness Model (SDTM)

A series of tiled models of superficial thickness covering the UK. The models are derived by direct modelling (natural neighbour interpolation) of BGS borehole records and BGS DiGMapGB-50. For the purposes of modelling, superficial deposits include sediments deposited during the Quaternary, subsequent Holocene rivers and coastal systems and also modern anthropogenic material, i.e. deposits that are less than 2.6 million years old. The 50 m x 50 m grids are overprinted with a minimum value so that areas where no bore data is present, but drift is known to occur, are given a minimum 1.5 m thickness. The superficial thickness models have been created as baseline datasets for the BGS Geohazard programme. They represent the first attempt by BGS to create nationwide models of such data and the models provide only a simple, mathematical interpretation of reality. The complexity of superficial deposits in Great Britain is such that it is only possible to model indicative values of thickness and elevation. The models should never be used as a substitute for thorough site investigation. The SDTM comprises three individual datasets; two datasets describe thickness variation and a third dataset details 'proximity' of the modelled data to the original source information. 1. The ASTM (Advanced Superficial Thickness Model) is a model of thickness variation indirectly derived from archive borehole records and map data. 2. The BSTM (Basic Superficial Thickness Model) is a model of thickness variation directly derived from archive borehole records. 3. The DBUFF (distance buffer) dataset is a calculation of spatial distance to the location of any data point used in the model. This provides the user with an indication as to how far the computer has had to interpolate and extrapolate the data from a measured observation point. For more information, refer to the user guide: The National Superficial Deposit Thickness Model (version 5).

Aeromagnetic Survey Of Great Britain And Northern Ireland

Digitised version of aeromagnetic survey records of Great Britain comprising a record for each digitised point, supported by survey and 'ends and bends' based line indexes. Original records include flight line records, worksheets, contour sheets and air photos provided by contractors at completion of each survey. Worksheets digitised by BGS during 1980's Smith and Royles 1989. Between 1955 and 1965 an airborne magnetic survey was conducted covering the land and parts of the sea areas of the United Kingdom. Different sections of the survey were conducted in different years by Hunting Geology and Geophysics Ltd. (variously Hunting Surveys Ltd. or Hunting Geophysics Ltd.) and Canadian Aeroservices Inc. The survey was funded by the Department of Scientific and Industrial Research and, in Northern Ireland, by the Department of Commerce. For the first year of survey funds were also provided by the Nuffield Foundation. The survey was overseen by the Geophysics Department of the (then) Geological Survey and Museum (subsequently Institute of Geological Sciences, subsequently British Geological Survey), in collaboration with the United Kingdom Atomic Energy Authority, Harwell, when local radiometric surveys were incorporated.

Results from the regional geochemical mapping of Britain

Laboratory results for the analysis of geochemical samples (stream sediments, soil and water) collected for the high resolution geochemical mapping of mainland Britain. The programme of regional geochemical sampling began in 1968 in the northern Highlands of Scotland. Sample sites are described on field slips. Chemical results are subjected to high level of quality control in the laboratory. Results are the raw data processed (standardisation and normalisation) to give seamless geochemical images and the value added G-BASE (Geochemical Baseline Survey of the Environment ) data in the BGS geochemistry database.

Zimbabwe Regional Geochemical Survey.

During the period 1982-86 a team of geologists from the British Geological Survey carried out a programme of regional geological mapping and geochemical exploration in collaboration with the Zimbabwe Geological Survey under a Technical Co-operation agreement supported by the UK Department for International Development (DFID) (formerly Overseas Development Agency). Three regions of Zimbabwe were mapped (Harare, Rushinga & Nyampanda, and Makaha) and the results of the stream sediment geochemical surveys were presented as three reports. Over 17,000 stream sediments were collected and analysed for Cu, Pb, Zn, Co, Ni, Mn, Li, As, Ba, Sn, Ta, and W. Raw data can be obtained from the Geological Survey of Zimbabwe, PO Box CY210,Causeway, Harare, Zimbabwe.

Ground investigation (site investigation) reports collection

Reports of ground investigations (also known as site investigations) produced by external organisations carried out for all forms of site investigation. The reports date back to the 1950s and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc. The collection covers the whole of Great Britain with concentrations around urban areas and transportation routes. The interpretive parts of the reports are not available to public. Reports from onshore Great Britain (or near shore) site investigations are held in the National Geoscience Data Centre in paper, microfilm or digital format. The entire collections at BGS Edinburgh has been scanned, but in BGS Keyworth currently only reports received since 2002 have been scanned. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format and are indexed in the Site Investigation Database and Detailed Accessions Database. The boreholes within the report, and any associated images, are linked to the Single Onshore Borehole Index.

Datasets produced by Multiscale Impacts of Cyanobacterial Crusts on Landscape Stability (3/6) (NERC grant NE/K011464/1, NE/K011626/1)

Data from laboratory experiments conducted as part of project NE/K011464/1 (associated with NE/K011626/1) Multiscale Impacts of Cyanobacterial Crusts on Landscape stability. Soils were collected from two sites in eastern Australia and transferred to a laboratory at Griffith University, Queensland for conduct of experiments. Soils were A, a sandy loam, and B a loamy fine sand. Trays 120 mm x 1200 mm x 50 mm were filled with untreated soil that contained a natural population of biota. Soils were either used immediately for experiments (physical soil crust only: PC) or were placed in a greenhouse and spray irrigated until a cyanobacterial crust has grown from the natural biota. Growth was for a period of 5 days (SS), c.30 days (MS2) or c.60 days (MS1). Following the growing period (if applicable) trays were placed in a temperature/humidity controlled room at 35° and 30% humidity until soil moisture (measured 5 mm below the surface) was 5%. Trays were then subject to rainfall simulation. Rainfall intensity of 60 mm hr-1 was used and rainfall was applied for 2 minutes (achieving 2 mm application), 8 minutes (achieving 8 mm application) or 15 minutes (achieving 15 mm application). Following rainfall, trays were returned to the temperature/humidity-controlled room under UV lighting until soil moisture at 5 mm below the surface was 5%. A wind tunnel was then placed on top of each tray in turn and a sequential series of wind velocities (5, 7, 8.5, 10, 12 m s-1) applied each for one minute duration. On each tray the five wind velocities were run without saltation providing a cumulative dust flux. For the highest wind speed, an additional simulation run was conducted with the injection of saltation sands. Three replicates of each rainfall treatment were made. Variables measured include photographs, spectral reflectance, surface roughness, fluorescence, penetrometry, chlorophyll content, extracellular polysaccharide content, Carbon, Nitrogen and splash erosion and particle-size analysis (of wind eroded material).

Cadmium isotope and trace element data records from four European and Tethys margin sites covering the 56 Ma Palaeocene-Eocene Thermal Maximum event

This dataset contains age-calibrated stable cadmium isotope records covering the 56Ma Palaeocene-Eocene Thermal Maximum (PETM) event, along with supporting molybdenum data and ANOVA (Analysis of Variance) statistics for each record. Samples analysed are mudrocks deposited during the PETM at four locations, Arctic Ocean, Svalbard, Central North Sea and Kheu River, southern Caucasus. Data was collected via bulk sediment digestion, ICP-MS/ICP-OES (concentration) and MC-ICP-MS (isotope) analytical techniques, with detrital correction and elemental enrichment calculations carried out using previously published upper crustal compositional data. These data were collected to independently trace changes in carbon burial trends across the event, using cadmium mass balance and cadmium-carbon relationships to model these changes. These data will be useful to those attempting palaeo-climate reconstructions, investigating climate change- related carbon cycle feedbacks, and developing metal isotope proxies for biogeochemical cycling in general. These data are published in Elms et al., 2026 (currently in review, AGU publications Geochemistry, Geophysics, Geosystems).
