Opencast Coal prospecting areas

The index includes outlines for some 8 000 opencast coal prospecting sites dating from the 1940s to date. The index leads to information on the records of some 1 million boreholes (additional to those shown in the Borehole Records layer) drilled during site exploration and also the accompanying plans and other data, all filed in 3 618 boxes. The sites include those that have been drilled and not worked and also those that have been exploited. Quote the site reference number and details of the information available can be purchased upon further enquiry to ngrc@bgs.ac.uk. It is hoped that in the near future more detailed information about the holdings can be supplied on-line.

Mineral Assessment reports

The UK Sand and Gravel Database was compiled during the production of the Industrial Mineral Assessment Reports. The Department of the Environment commissioned this Report series from the British Geological Survey. Each report studied the sand and gravel resources of an area of between one hundred and two hundred square kilometres. Specially commissioned boreholes were used in conjunction with existing geological knowledge to make a resource level assessment of the volume and quality of sand and gravel resource available. A total of 12 563 boreholes were drilled, 53 721 Lithological units described and 54 128 samples collected and graded. This information is presented in the appendixes of the individual reports and as a single database.

Mineral Occurrences

Britain has had a very long history of mining stretching back to pre-Roman times and the location of the many hundreds of thousands of old workings and mineral occurrences is poorly known. It has been estimated, for example, that there are up to 100 000 mineshafts in the South Pennine Orefield alone. Since its formation in 1835, the British Geological Survey as part of its mapping work has collected information on these locations in its archives and on its maps.

The Mineral Occurrences Database (MOD) aims to hold index level information on significant mineral occurrences in the UK including locations of known mines, mineral showings and localities, including sites where minerals of economic interest have been identified in panned concentrates. Data is normally taken from published sources or from internal BGS records, such as field sheets, rock and stream sediment collection cards. At present, the database does not hold information on energy minerals (coal, oil and gas) or bulk minerals (limestone, dolomite etc).

Information is held on the occurrence name(s), its geographical location, mineralisation features, minerals found, host rock, alteration, commodities produced and development events. Data is held in a corporate database and can be provided in a variety of database and spreadsheet formats. We can also supply the data in the common GIS formats (ArcView and MapInfo).

Mineral Reconnaissance Programme reports

The Mineral Reconnaissance Programme (MRP), funded by the Department for Trade and Industry (DTI), carried out mineral exploration reconnaissance in Great Britain between 1972 and 1997.The programme was very successful in that more than half the projects reported attracted significant commercial follow-up resulting in the discovery of many new prospects.

The locations of the investigations covered by each report are shown on the map. Further details and a summary of each report are given on the MineralsUK website.

Active mines and quarries

The map shows the location and name of active mineral workings in the UK and is derived from the BGS BritPits database.

The BritPits database of onshore mineral workings in the UK is based on the records of the BGS, the Coal Authority, industry sources and the Valuation Office Agency (Minerals) and is maintained by the BGS Onshore Minerals and Energy Resources Programme. The database describes individual workings, both currently active and formerly worked, in terms of name, location (including Mineral Planning Authority), ownership, basic geology, commodity produced and end-uses. Contact details including the operator's name, address, postcode and telephone and fax numbers are held where known. The location of over 6000 workings are held, with about 2000 currently being worked.

The data can be produced digitally, under licence, in formats to meet customer's requirements, such as locations of workings or operator's addresses, and is suitable for use in GIS applications using the British National Grid.

Directory of mines and quarries 1998

An important product of the database is a Directory with over 2000 current entries, each of which describes an active individual mineral working, by commodity, Mineral Planning Authority and operator, giving an alphabetically-arranged list of addresses of operators and sites. In addition there is an up-to-date commentary on the minerals industry accompanied by statistical information. The latest edition is available from the BGS Internet Shop, price £25 inc p&p.

Local geophysical surveys and flight lines.

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 in conjunction with the DTI Mineral Reconnaissance Programme in the 1970's and 80's, and many others were carried out 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. There are three data-sets; one showing the outline of the survey areas, another showing the actual survey lines within each area and another showing the survey points.

Superficial deposits 1:625 000 scale

The 'Superficial deposits' shown on the GeoIndex map includes the youngest geological deposits laid down in England and Wales, Scotland and part of Northern Ireland. This map is based on the first edition Drift 1:625 000 scale Geological Map of the United Kingdom published in 1977 as two sheets, North and South, available from the BGS Internet Shop.

The Superficial deposits, mainly formed in the Quaternary period of geological time, which extends from the present back to 2 million years ago. Many of the deposits were formed during episodes of glaciation ,or deposited by rivers. They occur as discontinuous patches and larger spreads and rest on top of the older rocks (referred to in the Bedrock).

Most of these Superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The name of each deposit or group of deposits corresponds to that shown on the published 1: 625 000 map e.g. River Terrace Deposits.

CAUTION

The source geological maps originally used to compile the published 1:625 000 maps are 1:50 000 and 1:63 360 (one inch to one mile) scale maps published before 1977. Many of these have since been up-dated and may therefore not now agree with the 1:625 000 geology shown here.

Because of the generalisation and simplification used in the compilation of this map, it should not be used to determine the detailed geology of any specific sites. It is best used to provide a basic understanding of the geology of the country in general, and for showing the geology of large regions where broad trends are more important than specific details.

Bedrock 1:625 000 scale

The 'bedrock' shown on the GeoIndex map comprises the bedrock geology, which represents the outcrops (at surface) and subcrops (at near-surface, beneath superficial deposits) in England and Wales, Scotland and part of Northern Ireland. It is based on the third edition Solid 1:625 000 scale Geological Map of the United Kingdom published in 1979 as two sheets, North and South. These sheets are available from the BGS Internet Shop.
