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.
