"The map covers the Nottingham-Humberside and East Anglian G-Base survey areas only. The dataset comprises 2374 analyses from a subset of G-Base surface samples (0-20cm depth) taken at a density of 1 sample per 2km2.

The texture data was captured for a joint research project between BGS, Rothamsted Research ( https://www.rothamsted.ac.uk/)and Nottingham University ( https://www.nottingham.ac.uk/geography/index.aspx), looking at methods of estimating particle size from geochemical analyses of topsoil. The work was originally published in the European Journal of Soil Science as a paper entitled "Estimating particle-size fractions of soil dominated by silicate minerals from geochemistry"( https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2389.2008.01112.x"" target=""_blank). The particle size analysis was carried out using laser granulometry and the data available in the viewer provides percentages (totalling 100%) of clay, silt and sand content. The map portrays the data in five simplified classes of soil. The European Soil Bureau code for the parent material underlying each sample is also provided."
