This layer of the map based index (GeoIndex) shows areas covered by explanatory sheet Memoirs, along with basic information such as memoir title and publication date. The memoirs themselves,compiled by BGS geologists, date from the late 1890s to present day and provide a comprehensive and detailed account of all aspects of the geology of the areas covered by the 1:50,000 (and 1:63,360) map series. Some memoirs may cover more than one geological sheet area and a few cover key geological themes (eg Jurassic rocks) across a large region. Sheet Descriptions are fully colour-illustrated, shortened accounts of the geology that are available for some of the newer published geological sheets.
Scanned images of the records of all onshore Great Britain (or near shore) boreholes, trial pits, shafts and wells held in the BGS archives in either paper, microfilm or digital format. The records range from simple single page lithological logs through to hydrocarbon completion reports. Current collection over 1million records with 50,000 new records added per annum. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection.
Scanned images of the records of onshore Great Britain (or near shore) site investigation reports held in the BGS archives in paper, microfilm or digital format. The entire collections in BGS Edinburgh have been scanned, but in BGS Keyworth currently only new reports received since 2002. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format (Tagged Image File Format). Indexed on the site investigation database and the boreholes within the report, and their images, are associated via the borehole database.
The map shows the localities where samples that form part of the BGS rock collections have been taken. Many of these samples are from surface exposure, and were collected by BGS geologists during the course of geological mapping programmes. Others are from onshore boreholes or from mine and quarry workings. The principal collections are the E (England and Wales), S (Scotland), N (continuation of the S collection) and the MR (miscellaneous). The collections, which are held at the BGS offices at Keyworth (Nottingham) and Edinburgh, comprise both hand specimens and thin sections, although in individual samples either may not be immediately available. Users may also note that the BGS holds major collections of borehole cores and hand specimens as well as over a million palaeontological samples. The Britrocks database provides an index to these collections. With over 120,000 records, it now holds data for some 70% of the entire collections, including the UK samples shown in this application as well as rocks from overseas locations and reference minerals. The collections are continuously being added to and sample records from archived registers are also being copied into the electronic database. Map coverage is thin in some areas where copying from original paper registers has not been completed. Further information on Britrocks samples in these and other areas can be obtained from the Chief Curator at the BGS Keyworth (Nottingham) office or from the rock curator at the BGS Murchison House (Edinburgh) office.
The collection consists of records of enquiries answered by the Land Survey from c.1939 to 1970, with a small number of earlier records. Pre c.1960 files relate mainly to economic mineral enquiries while files after that year relate increasingly to enquiries on geological site conditions. Enquiry records of former Leeds and Newcastle offices, relevant to UK(North), are held for c.1950 to 1992. Edinburgh Office enquiry files dated up to 1970 have been reviewed for retention/destruction and those of continuing informational or historical value have been retained as archives. Post 1970 files are confidential to BGS staff. Indexed on Land Survey Record Index (LSRI). Edinburgh enquiry files are referenced EE, (ex-Newcastle Office enquiries, EN). Covers Scotland and Northern England with concentrations in urban ares. All non-confidential data held by NGRC(North) is available to users.
Geological observations during field walks, with coordinates, photographs and descriptions of rocks/geological materials and features at the various stops.
Miscellaneous geological records for Scotland and Northern England of current or semi-current interest filed in order of accession. Some 65 accessions held which will be subject to review for permanent retention/destruction. Dataset created c.1970 and Indexed on Land Survey Record Index Database.
Records of all onshore (or near shore) boreholes, trial pits, shafts and wells held in the BGS archives in either paper, microfilm or digital format. The records range from simple single page lithological logs through to hydrocarbon completion reports. Spatial coverage will vary considerably depending on drilling activity, collecting activity and donations. The majority of new data is from site investigation reports with concentrations in urban areas and along transport routes. Current collection over 1million records covering the whole of Great Britain with 50,000 new records added per annum. Some records date back to 1600 but the majority date from 1900 onwards. Copies of records are available in hard copy or digital formats subject to confidentiality.
BGS offshore marine products are made available to view via this web map service. The 1:250 000 scale offshore geological maps in the UTM series (Universal Transverse Mercator projection) are available digitally as two themes: bedrock geology (DigRock250) and sea-bed sediments (DigSBS250). Marine Hard Substrate Dataset (DiGHardSubstrate250k) is also made available via this service.
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_v2014 dataset is available in a variety of formats from the BGS website www.bgs.ac.uk as free downloads, it supercedes the earlier 2012 version. The model complements the existing 1:625 000 scale mapsheets published by BGS utilising the same colour schema and geological classification. The component cross-sections extend to depths between 1.5 and 6 km; they have an aggregate length of over 25,000 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 together and incorporate around 300 deep stratigraphic boreholes across England and Wales. The sections also take account of the vast wealth of published data on the subsurface structure of Britain both from BGS and in the scientific 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 has been built in stages between 2009-14 using funding from the BGS National Capability Programme the Environment Agency of England and Wales, and the Nuclear Decommissioning Authority. Some 16 expert regional geologists compiled the sections.
