BGS Geology - 625k (DiGMapGB-625) Bedrock version 5

Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:625 000 scale providing a simplified interpretation of the geology and may be used as a guide at a regional or national level, but should not be relied on for local geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. The bedrock geology of the UK is very diverse and includes three broad classes based on their mode of origin: igneous, metamorphic and sedimentary. The data includes attribution to identify each rock type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volumes 1-3 ). The bedrock has formed over long periods of geological time, from the Archean eon some 7500 million years ago, to the relatively young Pliocene, 58 million years ago. The age of the rocks is identified in the data through their BGS lexicon name (published for each deposit at the time of the original survey or subsequent digital data creation). For stratified rocks i.e. arranged in sequence, this will usually be of a lithostratigraphic type. Other rock types for example intrusive igneous bodies will be of a lithodemic type. More information on the formal naming of UK rocks is available in the BGS Lexicon of Named Rock Units. Geological names are based on the lithostratigraphic or lithodemic hierarchy. The lithostratigraphic scheme arranges rock bodies into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition using visible features such as texture, structure, mineralogy. 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 delivered free of charge under the terms of the Open Government Licence.

Supplemental Information
The geology was fitted to a relevant topographic base at the time of production. The associated superficial data was not created at the same time and care should be taken using the two sets of data together as variation in topography at time of production may result in a mismatch between the two sets of data.

Statement
A new 1:625 000 scale (5th edition) printed geological map of the United Kingdom, published in 2007, was prepared digitally and these data were then used to create the replacement DiGMapGB-625 Bedrock Version 5. The 1:625 000 Bedrock data were created from two main sources. The geology for England & Wales, Scotland and the Isle of Man is generalised directly from the 1:50 000 scale DiGMapGB-50 V3 data released in 2006 with ongoing revisions through to 2007 incorporating selective interpretations from new 50k maps, anticipating their release as V5 tiles in 2008. The data for Northern Ireland were derived by minor simplification from the 1:250 000 scale geological map of Northern Ireland, published in 2007. Holes in the 50k data were filled using information from other sources.
