The sand and gravel resources of the country east of Solihull, Warwickshire : description of part of 1:25,000 sheets SP 17, 18, 27, 28

The assessment of the sand and gravel resources in the Solihull area, Warwickshire, 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 field work and fifty-eight 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 probability level. The district has been divided into three resource blocks containing between 11.3 and 13.1 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.
