Summary

Assessment of British sand and gravel resources

The sand and gravel resources of the UK were surveyed by the IMAU on a regional scale from 1968 to 1990. For each area surveyed a report was issued describing and quantifying the resources of sand and gravel, with an accompanying 1:25 000 map. The survey included drilling and sampling of the sand and gravel resources, logging of the borehole material and particle-size analysis to determine the proportion of gravel, sand and fines present. The maps categorise the sand and gravel resources as: exposed, present beneath overburden or potentially not workable.

Assessment of other industrial mineral resources

In addition to the sand and gravel resources, other industrial mineral resources were surveyed during the same period including: Celestite, Limestone and Dolomite, Conglomerate and hard rock resources.
