[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13480339]. This layer of the map based index (GeoIndex) shows the location of drillcore, bulk specimens, unwashed cuttings and processed material from onshore boreholes drilled in UK by BGS, commercial and public bodies. The majority of borehole cores and samples are available for study and sub-sampling by bona fide academics and commercial companies. Commercial companies are charged for access; academics will need to complete an academic waiver form.

[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13480339]. This layer of the Map based index (GeoIndex) shows the location of registered samples of drillcore and washed cuttings from onshore boreholes drilled in UK by BGS, commercial and public bodies, representing almost 10,000 boreholes. There is also a drillcore collection taken from onshore boreholes drilled in England and Wales by the BGS and commercial and public bodies.

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.

This Web service provides a spatial index into the BGS collection of onshore borehole materials in the UK and the Isle of Man, including drillcore, bulk specimens, washed and unwashed cuttings and processed material. The boreholes have been drilled by BGS, or by commercial or public bodies. The name of the borehole, its unique reference code and number (BGS_ID) and the type of material is provided. For some boreholes, multiple types of material are available. Details of the collection are held in the Borehole Materials Database, and may be accessed via the BGS website.

The British Geological Survey onshore borehole collection database of core and sample types and depths contains records of over 15 000 onshore boreholes drilled in the UK by BGS, commercial and public bodies. Material types include continuous drillcore, core samples, individual hand specimens, bulk samples, unwashed cuttings, washed and dried cuttings, plugs, powders and bulk samples. The physical collection and database was developed as part of the British Geological Survey's responsibility to establish and maintain a national borehole collection. Details of the collection are held in the Borehole Materials Database, and may be accessed via the BGS website. The collection was initiated in 1968, and the database is updated daily by the addition of new data and by modification of existing data. Most material is stored at the facility in BGS Keyworth. Some material is held at BGS Edinburgh. The majority of borehole cores and samples are available for study and sub-sampling by bona fide academics and commercial companies. Commercial companies are charged for access; academics will need to complete an academic waiver form. Some boreholes, especially recent hydrocarbon wells, are confidential, and depths and sample details may not be given. If you require further information about these boreholes, contact kwcorestore@bgs.ac.uk for details of the owner. In a few cases, the precise map references are also confidential.
