The sand and gravel resources of the country around Shrewsbury, Shropshire : description of 1:25,000 resource sheet SJ 41 and SJ 51

The assessment of the sand and gravel resources in the
Shrewsbury area, Shropshire, is based on the geological
maps and borehole records of the Institute of Geological
Sciences, records made available by the sand and gravel
industry, recent fieldwork and one hundred and seventy
three boreholes drilled for the Industrial Minerals
Assessment Unit.
All deposits in the area which might be potentially
workable for sand and gravel have been investigated
geologically and a simple statistical method has been
used to estimate the volume. The reliability of the
volume estimates is given at the symmetrical 95 per cent
confidence level.
The district has been divided into six resource blocks
containing between 10.0 and 22.1 km2 of sand and
gravel. For these blocks the geology of the deposits is
described and the mineral-bearing area, the mean
thickness of overburden and mineral, and the mean
grading of the mineral are stated. Detailed borehole data
are given. The geology, the position of the boreholes and
the outlines of the resource blocks are shown on the
accompanying map.
