  • 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 include geological logs and charts; letters, minutes & memos; notes; externally written reports; Internal reports; Research Reports; annotated publications, records and reports; and other miscellaneous documentation. Although some of the data go back to the first half of the 20th century (and rarely earlier), the bulk of the data refer to work carried out since about 1960. The data are filed under four subheadings: i. 1:50K sheet files (data relating to BGS mapping projects) for England & Wales, Scotland and Northern Ireland. ii. Offshore sheet files (data relating to BGS mapping projects) for the UK continental shelf and North Atlantic. iii. Offshore Quadrants (data relating to the hydrocarbons industry) (confidential). iv. Foreign biostratigraphy (in part confidential). v. General Palaeontology, Biostratigraphy & Taxonomy.

  • Rocks, thin sections and paper registers: samples from past BGS surveys and projects overseas. Though neglected for several years, the collection has been re-opened for addition of new material from overseas projects and donations. Paper registers are arranged by accession order on a country by country basis. The records have not been placed in electronic format and are not currently machine readable.

  • Manuscript geological maps produced by the Survey geologists or other recognised geologists on County Series (1:10560) and National Grid (1:10560 & 1:10000) Ordnance Survey base maps of Great Britain. A small number are produced at larger scale. Similar maps compiled from other sources. Maps produced since the 1850's, current holdings over 35,000 maps, all now scanned and available internally as image files.

  • A comprehensive collection of British fossil specimens and records compiled over 150 years of palaeontological collecting and research. Also includes all associated paper data, registers, indexes of locality and storage and reports of conclusions. The specimens have variable scattered coverage mostly within the UK and Ireland but there are some overseas data. Some specimens are sited accurately to less than 1 metre, whilst some specimens have accuracies of several kilometres. Includes both locality based biostratigraphic material, plus significant type, figured and cited samples of taxonomic importance. Specimens collected by Survey geologists throughout history of Survey, with some donated specimens (e.g. the Geological Society of London Collection) predating 1835, material is still being added. The collection includes hand specimens, casts & moulds, microfossil slides & cut sections and also registers containing identifications and locality information. The specimens have various uses within biostratigraphy and taxonomy. The data have key attribute data such as locality, stratigraphic age, matrix lithology, taxonomy, etc that could be used for linking in other datasets. Access and use of the data is subject to current policies, inline with MDA's (Museum Documentation Association) Spectrum guidelines and MLA's (Museum Libraries Archives Council) Accreditation guidelines. The collection can be viewed by loan or visit, whilst copies of the associated paper data can be made available as photocopy, scan, spreadsheet, etc., subject to certain constraints and conditions.

  • In 2011 the British Geological Survey (BGS) decided to begin the assembly of a National Geological Model (NGM) from its existing and on-going geological framework models , comprising integrated national crustal, bedrock and Quaternary models. The bedrock component is the most advanced of these themes and comprises both the calculated models and a complementary network of cross-sections that provide a fence diagram for the bedrock geology of Great Britain. This fence diagram, the GB3D_v2012 dataset is available in a variety of formats from the BGS website www.bgs.ac.uk as free downloads. It complements the existing 1:625 000 scale mapsheets published by BGS utilising the same colour schema and geological classification. The 121 component cross-sections extend to depths between 1.5 and 6 km; they have an aggregate length of over 20,000 km, and they are snapped together at their intersections to ensure total consistency. The sections are based on the existing BGS geological framework models where they cut through them, they also take account of the vast wealth of published data on the subsurface structure of Britain both from BGS and in the literature. Much of this is in the form of cross-sections, contour maps of surfaces, and thicknesses (isopachs). The fence diagram has been built in the Geological Surveying and Investigation in 3D (GSI3D) software. It is envisaged that this dataset will form a useful educational resource for geoscience students and the general public, and also provide the bedrock geology context and structure for regional and catchment scale studies. The fence diagram was built in 2009-12 using funding from the BGS National Capability Programme and the Environment Agency of England and Wales. 14 expert regional geologists compiled the sections.

  • A list of the laboratory reports produced from testing in the engineering geology laboratory. It includes report number, title and author's name(s). The reports themselves contain data on a wide range of geotechnical and geophysical laboratory tests, from standard and index tests to complex research. Test materials are highly varied, soils and rock, from the UK or overseas.

  • Added value microfossil analyses carried out on material from the British Continental shelf are included. Sample number, borehole details, locality and geological information are given together with microfossil identification. The identification logging sheets are housed in box files. Symbols included: CSA1-2205 Continental Shelf Unit North; CSB1-6047 Continental Shelf Unit South; CSC1-7134 Offshore microfossils; CSD1-507 Offshore microfossils; CSE1-6826 Offshore microfossils (incidental and occasional macrofossil data are included). The raw data is held in CONTSHELFRAW and the interpretative reports relating to the microfossils are held elsewhere (TECHREPORTS).

  • The Land Survey Plans collection of c.1,520 plans consists largely of mine plans acquired by the Survey, including 492 non-coal mine plans deposited by the National Coal Board 1984-87, and copies of mine plans derived from various sources including '6-inch reductions'. The collection also contains about 500 miscellaneous plans extracted from other Land Survey records in order to benefit from specialised systems of archival storage. The Survey's collection of Northern England mine plans are being added to the LSP collection. The collection supplements the Plans Of Abandoned Mines (Other than Coal & Oil Shale) in Scotland (NONCOALPLANSCO) providing an index to plans other than coal and oil shale for Scotland. Indexed on BGS Plans Database Index. Coal Authority hold some non-coal plans for Scotland. All non-confidential data held by NGRC(N) is available to users. Mainly coalfield areas of Central Scotland.

  • Reports of work carried out worldwide by the BGS and its precursors. These reports cover a wide range of scientific and technical disciplines and were produced for a variety of purposes. Reports date from about 1950 although there are only a comparatively small number of reports pre 1960. The reports are not published but copies can be provided on demand, in hard copy or pdf format ,subject to any restrictions.
