The Regional Geochemical Atlases are the principal hard copy product of the British Geological Survey G-BASE (Geochemical Baseline Survey of the Environment) project. The majority of atlases are for stream sediment, with data on stream water and soil included where available. Separate stream sediment, soil and stream water atlases have been published for Wales. This dataset relates to the hard-copy atlases, which are available for Shetland, Orkney, South Orkney and Caithness, Sutherland, Hebrides, Great Glen, East Grampians, Argyll, Southern Scotland, Lake District, NE England, NW England and N Wales and Wales. The atlases were issued between 1978 and 2000. Each atlas comprises a set of separate interpolated heat-maps for each analyte, as well as descriptive and interperative information. The atlases provide an invaluable, systematic baseline of geochemical information for Great Britain, serving as a marker of the state of the environment against which to measure future change. Digital atlases and map products are also available for the Clyde Basin, central England, the London region and south-west England. National-scale digital atlas products are also available.
