The conglomerate resources of the Sherwood Sandstone Group of the country east of Stoke-on-Trent, Staffordshire : description of 1:25,000 resource sheet SJ 94

The geological maps of the Institute of Geological Sciences, pre-existing borehole information and 6 boreholes drilled for the Industrial Minerals Assessment Unit, form the basis of the assessment of the conglomerate resources of the Sherwood Sandstone Group of the country east of Stoke-on- Trent, Staffordshire. All deposits of the Sherwood Sandstone Group in the district which might be potentially workable for aggregate have been investigated and estimates of their volume have been inferred. The 1:25 000 map is divided into five resource blocks containing between 0.3 and 5.6 km2 of Sherwood Sandstone Group outcrop. For each block the geology of the deposits is described while data from boreholes and natural and quarry exposures are discussed. The geology, the position of the boreholes and the outlines of the resource blocks are shown on the accompanying map.
