BGS Geology - 50k (DiGMapGB-50) Superficial version 8
Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:50 000 scale. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 2.58 million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by ice, water, wind and weathering. As such, the deposits are denoted by their BGS Lexicon name, which classifies them on the basis of mode of origin (lithogenesis) with names such as, 'glacial deposits', 'river terrace deposits' or 'blown sand'; or on the basis of their composition such as 'peat'. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The digital data includes attribution to identify each deposit type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volume 4). The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

The BGS Geology 50k dataset is a digital representation of the geology of Great Britain at 1: 50 000 scale (or 1:63 360 scale for areas surveyed and published prior to 1970). It is a compilation of digital tiles derived from previously published and unpublished maps, archive information and results of field mapping campaigns. The mapping, description and classification of rocks are based upon the interpretations and evidence available at the time of survey, or time of re-evaluation for modifications/correction. The data has been digitally captured from paper record, originally using Bentley MicroStation and latterly ESRI ArcGIS software. Post capture processing has occurred to combine geometry and attribution from existing BGS data resources. Quality control checks are run on individual data batches prior and subsequent to their integration into the main data mosaic. The source dataset is dynamic in nature with periodic comprehensive data releases.
