Soil Texture

The map covers Great Britain and integrates geology and soil characteristics at a scale of 1:50 000 (visible at higher zoom levels), with a 1km resolution version available for regional overview.

The simplified texture classifications are derived from measured soil textures (%clay, %Silt and %Sand) taken from archive GBASE and geotechnical samples held by BGS. The samples are compared with a simplified soil-texture triangle used for mySOIL and are grouped by their underlying soil-parent material type to show a map of distribution of the classes; expert judgment has been used to estimate a texture class where sample data is not available). Note that the map uses terms that refer to: Sandy soils, Silty soils, Clayey soils and Loamy soils with additional indicators for the presence of Chalk fragments (Chalky) and Peat (Peaty). Most parent materials generate a broad range of soil textures so these terms should be regarded as 'indicative'. Further information is available from the mySOIL resource page. The GBASE laser granulometry dataset (used in this map later) is also available in the UKSO map viewer.
