[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13603141] These are scanned and georeferenced raster versions of the 1400 Ministry of Housing and Local Government (MHLG) Mineral Planning Permissions Maps (see associated metadata). The 1:25000 scale maps recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). The mineral planning permission polygons recorded on the maps have been digitised to create vector GIS polygons (see associated metadata for MHLG Planning Permission Polygons).

A collection of approximately 1400 Ordnance Survey 1:25 000 paper maps upon which the former Ministry of Housing and Local Government (MHLG) recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). Priority was placed on areas that had given rise to then current casework issues, so at the time when the maintenance of the maps ended, some authority information had been updated recently whereas other areas had not been visited for many years. Therefore, the variable completeness of the data should be kept in mind when the material is being used. Both the maps and the card index have been used to create the digital mineral planning permissions polygons (see metadata for MHLG Planning Permission Polygons). Polygons for worked ground have not been captured.

A card index storing supplementary information regarding name, operator, dates and commodity worked for each planning permission boundary recorded (drawn) on the Ministry of Housing and Local Government (MHLG) Mineral Planning Permissions Maps (see associated metadata). Information on the cards has been used to attribute the Ministry of Housing and Local Government (MHLG) Mineral Planning Permission Polygons (see associated metadata for MHLG Planning Permission Polygons).

'Archive' collection of c.3,000 records of the former Industrial Minerals Assessment Unit (IMAU) relating to sand and gravel assessment projects in Scotland, 1978-88. Includes borehole and trial pit records, grading and resource assessment data and aggregate tests.

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. Data collection extended from the first IMAU report in 1969 to the last report in 1990. The dataset is complete and is derived from reports with some additional boreholes that were never published. Standard procedures were adopted for whole project. Each report studied the sand and gravel resources of an area of between one hundred and two hundred square kilometres. Specially commissioned boreholes on a one kilometre grid basis 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. Data collection is complete. Only factual corrections to the data are occasionally made. The dataset includes the borehole location, total depth, unit thickness, unit lithologies, and grading information.

This dataset provides digital spatial information on the location of mineral resources in England at a scale of 1:50 000. The term ‘mineral resources’ has a definition under international standards that includes both an economic and geological dimension. These data are based primarily on mapped geology with limited assessment of economics. Therefore, the term ‘mineral resources’ is used here in a broad sense. The dataset allows users to visualise the extent and distribution of mineral resources and to relate them to other forms of land-use (such as urban areas or designated environmentally sensitive areas) or to other factors (such as transport infrastructure and conservation information). The dataset is derived from a set of commissioned projects to prepare a series of mineral resource maps based on counties or amalgamations of counties. Maps for England were commissioned by the central government department with responsibility for mineral planning at the time (Department of the Environment (DoE), Department of the Environment, Transport and the Regions (DETR), Department for Transport, Local Government and the Regions (DTLR), Office of the Deputy Prime Minister (ODPM), and the Department for Communities and Local Government (DCLG) between 1994 and 2006. Each map produced (with an accompanying report describing the mineral resources depicted on the map) is available to download, as a PDF file from the BGS-hosted website: www.MineralsUK.com. During 2011-2012 revisions were made to areas of the resource linework. These changes were made as a result of new research and release of a new version of DiGMap (v5). This work was on an ad hoc basis but affects all resource layers. In 2020 minor revisions to geometry and attributes were made in in response to minor corrections that were required. The paper maps were not re-released with these data updates. The BGS Mineral Resource data does not determine mineral reserves and therefore does not denote potential areas of extraction. Only onshore, mainland mineral resources are included in the dataset. This dataset has been produced by the collation and interpretation of mineral resource data principally held by the British Geological Survey. The mineral resource data presented are based on the best available information, but are not comprehensive and their quality is variable. The dataset should only be used to show a broad distribution of those mineral resources which may be of current or potential economic interest.

This mineral resource data was produced as part of the Mineral Resource Map of Northern Ireland via a commission from the Northern Ireland Department of the Environment. The work resulted in a series of 21 data layers which were used to generate a series of six digitally generated maps. This work was completed in 2012 with one map for each of the six counties (including county boroughs) of Northern Ireland at a scale of 1:100 000. This data and the accompanying maps are intended to assist strategic decision making in respect of mineral extraction and the protection of important mineral resources against sterilisation. They bring together a wide range of information, much of which is scattered and not always available in a convenient form. The data has been produced by the collation and interpretation of mineral resource data principally held by the Geological Survey of Northern Ireland and was funded via a commission from the Northern Ireland Department of the Environment. These layers display the spatial data of the mineral resources of Northern Ireland. There are a series of layers which consist of: Bedrock: Clay, Bauxitic clay, Coal & Lignite, Coal – lignite proven, Conglomerate, Dolomite, Igneous and meta-igneous rock, Limestone, a 100m buffer layer on the Ulster White Limestone, Meta-sedimentary rocks, Perlite, Salt, Sandstone and Silica Sand. Superficial (unconsolidated recent sediments) : Sand & gravel and Peat. The data except for the salt and proven lignite resource layers was derived from the 1:50 00 and 1:250 000 scale DigMap NI dataset. This version of the data retains the internal geological boundaries which are dissolved out in the accompanying dissolved version. A user guide 'The Mineral Resources of Northern Ireland digital dataset (version 1)' OR/12/039 describing the creation and use of the data is available.

The original version of this dataset contained lithologies interpreted as representing a mineral resource for mineral extraction. Collated on a County by County basis as part of the former Office of the Deputy Prime Minister (ODPM) Mineral Resource Information in support of National Regional and Local Planning between 1994 and 2006. A primary objective is to produce baseline data in a consistent format that can be updated, revised and customised to suit planning needs, including Mineral Local Plans and Regional Planning Guidance, as well as those of industry. The BGS Mineral Resource data does not determine mineral reserves and therefore does not denote potential areas of extraction. Only onshore, mainland mineral resources are included in the dataset. This dataset has been produced by the collation and interpretation of mineral resource data principally held by the British Geological Survey. The mineral resource data presented are based on the best available information, but are not comprehensive and their quality is variable. The dataset should only be used to show a broad distribution of those mineral resources which may be of current or potential economic interest. The data should not be used to determine individual planning applications or in taking decisions on the acquisition or use of a particular piece of land, although they may give useful background information which sets a specific proposal in context.

The map show the broad distribution of the industrial, including construction, mineral resources of Britain and the main sites where these are worked. Over extensive areas bedrock is covered by superficial deposits, including economically important sand and gravel resources. These superficial deposits are not shown on the map. Resources have been defined by dominant lithology (rock type). The map is a synthesis of the mineral resources and mineral working data held by the BGS in 1996. The published (paper) map has not been superseded however the digital mineral resources and mineral workings data has since been superseded. The map is logically consistent throughout.
