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.
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.
Index to borehole material held chiefly as continuous drillcore, bulk samples, unwashed cuttings and processed material from onshore UK.
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.
The BGS collection of paper and sepia geophysical logs from boreholes drilled by BGS and external organisations. The majority of the collection are in hard copy , but significant numbers are now available digitally. Covering the UK mainland and offshore from 1949 onwards. the commercial logs are mainly related to hydrocarbon , coal exploration or water wells. The collection covers Great Britain and the types of logs and the scales used will vary depending on the equipment available and the use of the data.
Collection of reports, interpretations and records of research in British coalfield areas deposited by British Coal. Data for past and current collieries and for future prospects. Some 1000 linear feet (300m) of data. Information within the reports date from the 19th Century up to the present day.
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.
Index to BGS geological map 'Standards', manuscript and published maps for Great Britain produced by the Survey on County Series (1:10560) and National Grid (1:10560 & 1:10000) Ordnance Survey base maps. 'Standards' are the best interpretation of the geology at the time they were produced. The Oracle index was set up in 1988, current holdings are over 41,000 maps. There are entries for all registered maps, but not all fields are complete on all entries.
Index to 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. The index was set up in 1991. Current holdings for Great Britain are over 35,000. There are entries for all registered maps but the level of detail depends on nature of original Survey, ie not all fields are complete for all entries.
Index of onshore boreholes in England, Wales and Scotland for which BGS holds material either as registered specimens or cuttings. Developed to improve access by BGS staff and external enquirers to the major UK borehole collection.
