The UK Sand and Gravel Database was compiled during the production of the Industrial Mineral Assessment Reports. The Department of the Environment commissioned this Report series from the British Geological Survey. Data collection extended from the first IMAU report in 1969 to the last report in 1990. The dataset is complete and is derived from reports with some additional boreholes that were never published. Standard procedures were adopted for whole project. Each report studied the sand and gravel resources of an area of between one hundred and two hundred square kilometres. Specially commissioned boreholes on a one kilometre grid basis 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. Data collection is complete. Only factual corrections to the data are occasionally made. The dataset includes the borehole location, total depth, unit thickness, unit lithologies, and grading information.

An important paper archive of a wide variety of miscellaneous geological information organised on the basis of its location within 1:10 000 scale geological map sheet areas in Great Britain. The majority of the data has been produced or collected from a wide variety of sources by BGS staff since 1835. Mainly acquired as part of the mapping programme new information is added on a regular basis. The data may not fit into any of the main collections, but is valuable for future projects and answering enquiries.

This Web service provides the BGS heat flow dataset as a Web Map Service (WMS). The British Geological Survey (BGS) heat flow model (United Kingdom) is derived from a catalogue of legacy heat flow data points and ground-heat modelling. The model portrays heat flow as a continuous modelled surface, interpolated between observation and estimation points. Heat flow data is typically used to determine temperatures beneath the ground surface, and model how much thermal energy may be recovered from or stored within.

This dataset shows the geographic extents of Mineral Assessment Reports covering sand and gravel resources and selected other industrial minerals across the United Kingdom. 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.
