This dataset provides a digital spatial representation of the Mineral Planning Authorities (MPAs) across the United Kingdom. Each polygon represents an administrative area responsible for mineral planning and regulation and is linked to the relevant onshore mineral resource maps and accompanying reports for that area. The Mineral Planning Authority areas broadly align with the administrative units used in the preparation of BGS mineral resource maps. In England and parts of South Wales, these maps were produced following a commission to BGS by the Office of the Deputy Prime Minister (now the Ministry of Housing, Communities and Local Government) through the research project Mineral resource information in support of national, regional and local planning. This work was completed in 2006 and resulted in a series of digitally generated mineral resource maps at a scale of 1:100 000, covering administrative areas across England and parts of South Wales. In Scotland, BGS was awarded funding from the Scottish Government Aggregates Levy Fund in 2007 to develop a comprehensive and accessible mineral resource information base for 18 local authorities within the Central Belt of Scotland. This work was co-funded through the BGS Sustainable Mineral Solutions project and was completed in March 2008. The project outputs included a guide to minerals information for the Central Belt and a series of digitally generated mineral resource maps at a scale of 1:100 000. In Wales, BGS was awarded funding from the Welsh Government-administered Aggregates Levy Sustainability Fund for Wales in 2009 to develop a comprehensive mineral resource information base covering Wales. The project was co-funded through the BGS Sustainable Mineral Solutions team, part of the Minerals and Waste Science Programme, and was led from the BGS Cardiff office. This work was completed in July 2010 and produced a series of six digitally generated mineral resource maps at a scale of 1:100 000, together with supporting mineral resource information for Wales. A primary objective of this work was to provide baseline mineral resource information in a consistent, updateable format to support mineral planning, including use in mineral development plan documents and regional spatial strategies. This Mineral Planning Authority spatial layer provides a framework for accessing these mineral resource maps and reports, supporting mineral planning, land-use decision making and resource management.
