The index polygons represent the areas surveyed, typically between 100 and 200 square kilometres, for which individual reports and accompanying 1:25 000 scale maps were produced. The sand and gravel resources of the UK were surveyed on a regional basis by the Industrial Minerals Assessment Unit (IMAU) between 1968 and 1990. Each survey area was investigated through drilling and sampling of sand and gravel deposits, borehole logging, and particle-size analysis to determine the proportion of gravel, sand and fines. The accompanying maps categorise resources as exposed, present beneath overburden, or potentially not workable. In addition to sand and gravel, other industrial mineral resources were assessed during the same period, including celestite, limestone and dolomite, conglomerate, and hard rock resources. Selecting individual polygons provides details of the corresponding report, including title, report number, author(s), subtitle and publication date. The Mineral Assessment Report series was commissioned by the Department of the Environment and undertaken by the British Geological Survey.

Each report studied the sand and gravel resources of an area of between one hundred and two hundred square kilometres. Specially commissioned boreholes were used in conjunction with existing geological knowledge to make a resource level assessment of the volume and quality of sand and gravel resource available. A total of 12,563 boreholes were drilled, 53,721 Lithological units described and 54,128 samples collected and graded. This information is presented in the appendixes of the individual reports and as a single database.
