Mineral resource information in support of national, regional and local planning : West Yorkshire (comprising Metropolitan Boroughs of Bradford, Calderdale, Kirklees and Wakefield and City of Leeds)

This report is one of a series prepared by the British Geological Survey for various administrative areas in England for the Office of the Deputy Prime Minister’s research project Mineral Resource Information in Support of National, Regional and Local Planning. The accompanying map relates to West Yorkshire, comprising the Metropolitan Boroughs of Bradford, Calderdale, Kirklees and Wakefield and the City of Leeds, and delineates the mineral resources of current, or potential, economic interest in the area and the sites where minerals are, or have been, worked. It also relates these to national planning designations, which may represent constraints on the extraction of minerals. Three major elements of information are presented: • the geological distribution and importance of mineral resources; • the extent of mineral planning permissions and the location of current mineral workings; and • the extent of selected, nationally-designated planning constraints. This wide range of information, much of which is scattered and not always available in a consistent and convenient form, is presented on a digitally-generated summary map on the scale of 1:100 000. This scale is convenient for the overall display of the data and allows for a legible topographic base on which to depict the information. However, all the data are held digitally at larger scales using a Geographical Information System (GIS), which allows easy revision, updating and customisation of the information together with its possible integration with other datasets. The information will form part of a Summary of the Mineral Resources of the Yorkshire and the Humber Region
