Dataset description

A superficial thickness model covering England Scotland and Wales. The model is derived by direct modelling (natural neighbour interpolation) of BGS Borehole records and BGS Digmap. For the purposes of modelling, superficial deposits include sediments deposited during the Quaternary, subsequent Holocene rivers and coastal systems and also modern anthropogenic material. i.e. deposits that are less than 2.6 million years old. Grids are overprinted with a minimum value so that areas where no bore data is present, but superficial deposits are known to occur are given a minimum 1.5m thickness. The superficial thickness model has been created as baseline datasets for the BGS Information Products programme. The model provides only a simple, mathematical interpretation of reality with some phantom points that improve the model mainly in valley areas where lack of data was given different results as those expected by a geological interpretation of the area. The complexity of Superficial deposits in Great Britain is such that it is only possible to model indicative values of thickness and elevation. The models should never be used as a substitute for thorough site investigation.
