GIS Data Layer and Database including maps and detailed Indexes. Paper records and photographs, descriptive register is paper version from which the digital version was created. Data mainly captured in 1989, infrequent additions (approximately 1 entry per year) since then. Includes all man-made caves known to BGS in Nottingham, but there are many more to be located in the future.
This digital data set contains original files of seismic reflection survey location (navigation) data and dates from the late 1970s. These provide location information for the Digital Seismic Sections data set (DIGSEISECS) and some of the printed seismic sections of the Original Seismic Sections dataset (ORIGSEISECS) and Copy Seismic Sections dataset (COPYSEISECS). 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 (British Geological Survey) and other public-sector bodies, e.g. BIRPS (The British Institutions Reflection Profiling Syndicate), for academic research. The data are used with the Seismic Locations and Sections Database (LOCSEC) and for workstation-based interpretation. There are approximately 20 tapes and 15 Exabyte cartridges. The data are mostly concentrated in coal, oil and gas prospecting areas.
This dataset contains the .tif (Tag Image File Format) scans of all the applied geology maps (otherwise known as thematic or environmental) and sections produced as part of "Geological background for planning and development" and preliminary sand and gravel projects carried out by the British Geological Survey for the Department of the Environment, Scottish Development Department and Scottish Office from 1975 to 1996. The maps and sections cover a number of themes for specific areas relating to the project area within the United Kingdom. Metadata on the maps, sections and project reports are in the associated excel spreadsheet. The geological line work and the methods used to produce the maps are those current at the time of production. Map scales are 1:10 000, 1:25 000 and 1:50 000. The maps have Ordnance Survey map bases and are bounded by the project area. The maps could be used for geological, engineering geological, environmental and resources research, as an information and reference resource and for inclusion in reports and papers. There are no access or usage constraints for BGS staff for BGS purposes. The scans are .tif files and can, therefore, be displayed using any suitable package. The original file size varies between 170 kb to 250 Mb. The dataset is stand-alone.
The Single Onshore Borehole Index (SOBI) is an index of over 1 million boreholes, shafts and wells and references collections of digital and analogue records from all forms of drilling and site investigation work held by the BGS. The index covers onshore and near shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Some 50,000 new boreholes are added each year. The majority of the records contain written descriptions of the ground encountered. The SOBI index database originated in 1988 from a number of existing tables and from data input from a variety of coding forms. Therefore not all fields in the database are populated and data that should be in some fields may currently form part of the entries in another. The index is available on the BGS website via the Geoindex
This is the core collection of photographs in BGS it represents photographs taken by professional photographers and selected by subject and quality for public reference in the BGS libraries. The collection dates from c 1890 to c.1995 and is organized in a series of sub-collections depending on which office the photographers were based. The collection covers photography taken in the field during the geological mapping programme. Series A, the main Land Survey collection for England and Wales, are all taken by professional photographers and are of high quality. Dates from c.1890 to the start of the current "P" system, the first 7500 are glass plates. Series B, Edinburgh, part of the main Land Survey collection for Scotland, full plate size and all glass plates. Series C, Edinburgh, part of the main Land Survey collection for Scotland, half plate size. Series D, Edinburgh, part of the main Land Survey collection for Scotland consists of large format negative size with additional 35mm transparencies, earlier parts of the collection are black and white, later, colour. Series L, Keyworth, the main Land Survey collection for Northern England and Wales emanating from the Leeds Office, all are taken by professional photographers and include large format black and white, colour originals and colour 35 mm transparencies. Access constraints are only physical constraints relating to handling negatives and glass plates. scans are available in the Geoscience Imagebase. Photographs are either: Out of copyright; Crown or NERC.
The database contains an index to over 600 ground geophysical surveys carried out in the UK for a variety of projects. A large number of these surveys were done for the DTI Mineral Reconnaissance Programme in the 1970s and 80s; many others were done at the request of BGS field mapping groups. Information held describes the survey objective, location of measurements, geophysical methods and equipment used, reports and publications, storage locations of data and results (for analogue and digital data), dates and personnel.
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 Land Survey Archives consists of records of the Geological Survey in Scotland for permanent retention dating from 1860s onwards. The collection comprises geologists' field notebooks, miscellaneous field observations and reports, historical and biographical material, correspondence files, photographs, etc. Includes archival material deposited by outside individuals and organisations, eg. NCB (National Coal Board) Bore Book Collection. Survey archival material for Northern England will be incorporated. Some 380 accessions held amounting to over 7,000 items. Indexed at collection level in Land Survey Record Index (LSRI). Plans abstracted and held separately in Land Survey Plans Collection.
As an integral part of the investigations carried out at Sellafield, and to a lesser extent for the Dounreay boreholes, the cores from the boreholes were systematically examined by geologists and samples selected for detailed petrographic analysis. Thin sections were prepared from many of these samples. Some of the samples were then prepared for analysis using X-ray fluorescence, X-ray diffraction or scanning electron microscopy. Samples containing fluid inclusions were prepared as doubly polished fluid inclusion wafers. Thin sections were prepared from soil materials obtained from the investigations of the Quaternary deposits. Particular attention was given to samples of the mineralisation that was identified in the formations at Sellafield. In addition to the samples from the boreholes, there are also some samples obtained from surface exposures that were examined during the regional surveys. The samples and sections have been catalogued and incorporated into the national collection by the British Geological Survey. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.
During the period from 1989 to 1997, Nirex undertook extensive geological investigations at sites near Sellafield, in Cumbria, and Dounreay, in Caithness, to examine whether or not they were suitable locations for a deep repository for radioactive waste. At Sellafield, thirty deep boreholes, and a further thirty-five shallow boreholes, were drilled. The majority of the deep boreholes were drilled to obtain continuous core and some 18.7km of rock core arose from the investigations. Two deep boreholes were drilled at Dounreay, totalling 2,286 metres of drilling. Again, much of the drilling was to obtain continuous core. In most of the boreholes a suite of data acquisition techniques were used, including: continuous coring, geophysical wireline logging, hydraulic testing, sampling and analysis of groundwaters. Mineralogical data were acquired by detailed core observation, petrographic analysis, fluid inclusion analysis and stable and radiogenic isotope studies. Testing on samples from the rock cores was undertaken to determine petrological, mineralogical, hydrogeological, geophysical and geotechnical parameters. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.
