Abstract:

The British Geological Survey (BGS) was awarded a grant from the Welsh Assembly Government Aggregates Levy Fund in 2009 to provide a comprehensive, relevant and accessible information base to enhance the sustainability of mineral resources for Wales. BGS co-funded this project through its Sustainable Mineral Solutions project. This work was completed in 2010. This dataset comprises the digital GIS files which were produced through this project. The major elements of minerals information presented on the maps are; the geological distribution of all onshore mineral resources in Wales, the location of mineral extraction sites, the recorded occurrences of metallic minerals, the recorded location of former slate quarries and significant areas of slate waste and the recorded location of historic building stone quarries. 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.

Supplemental Information:

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 inferred boundaries shown are, therefore, approximate. Mineral resources defined in the data delineate areas within which potentially workable minerals may occur. These areas are not of uniform potential and also take no account of planning considerations that may limit their working. The economic potential of specific sites can only be proved by a detailed evaluation programme. Such an investigation is an essential precursor to submitting a planning application for mineral working. The individual merits of the site must then be judged against other land-use planning issues. Extensive areas are shown as having no mineral resource potential, but some isolated mineral workings may occur in these areas. The presence of these operations generally reflects very local or specific situations. The pattern of demand for minerals is continually evolving due to changing economic, technical and environmental factors. 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. Criteria used to define resources, for example in terms of mineral to waste ratios, also change with location and time. Thus a mineral deposit with a high proportion of waste may be viable if located in close proximity to a major market, but uneconomic if located further away. These criteria vary depending on the quality of the information available. The extents of mineral resources shown in these data are generally the inferred surface expression of the resource. However, users should note that workable minerals may extend beneath overburden which is adjacent to the outcrop area shown. Bedrock resource for the commodity may exist underneath where a superficial deposit for the same commodity is shown. Bedrock deposits are not shown underneath the superficial deposits for the same commodity type to ensure that the commodity layer is topologically correct (i.e. polygons do not overlap) and can be used in a GIS system for analysis. The Mineral Resource dataset has been developed at 1:50 000 scale and must not be used at larger scales. Digital map data should therefore be used at about the same scale as their original compilation; for example 1:50 000 scale data should not normally be blown up and used at 1:10 000 scale. Most geological maps were originally fitted to a particular topographic base and care must be taken in interpretation, for example when the geological data are draped over a more recent topography. All spatial searches against the data should be done with a minimum 50 m buffer. Mineral resources defined in the data delineate areas within which potentially workable minerals may occur.

statement:

[1] BGS DiGMapGB-50 version 5 geology polygons were clipped to the county boundary. [2] A list and map of the geological lithologies for each county were supplied to the Economic Geologist for interpretation of which bedrock and superficial geological formations might now, or in the foreseeable future, be of economic value. [3] Interpretations are then extracted from the derived from DiGMapGB-50 version 5 and given a mineral resource attribute and colour. [4] Maps were re-supplied to the Economic Geologist for correction. Small areas of resources were deleted when considered to be uneconomic/unworkable. [5] Drafts of the finished maps taken to stakeholders for comment. [6] Maps approved and digital data, collated for each map, sent to GIS specialist for dataset preparation and cleaning. [7] Data produced for each map was merged together to produce regional files based on resource commodity. [8] Mineral commodity and name attributes are correctly assigned using the legend supplied by Economic Geologist. [9] Polygons dissolved based on name attribute, removing all county boundaries. [10] Remove sliver polygons (created as a result of geological sheet boundaries) where possible and re-dissolve. [11] Multipart to single part operation conducted on each dataset. [12] Redundant attributes removed. [13] Repair geometry operation to clean the dataset. [14] Economic Geologist approves final resource dataset.
