This dataset provides digital spatial information on the location of mineral resources across the onshore area of the United Kingdom 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 across the UK 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 UK dataset has been created by integrating mineral resource datasets originally produced for England, Scotland and Wales through a series of commissioned and grant-funded projects led by the British Geological Survey (BGS) between 1994 and 2010. These national datasets were developed separately, using a consistent geological evidence base and interpretation approach, and have subsequently been harmonised and merged to support UK-wide online spatial delivery. 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.
