Abstract:

Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:250 00, providing a generalised geology. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. 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 Great Britain 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 (RCS) (volumes 1-3). The bedrock has formed over long periods of geological time, from the Archean Eon, some 3500 million years ago, to the relatively young Pliocene, 58 million years ago. The age of the rocks is identified in the data through their name in the BGS Lexicon of Named Rock Units (published for each deposit at the time of the original survey or subsequent digital data creation). For stratified rocks, i.e. those 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 rocks or 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 available under BGS data licence.

statement:

Each 100 x 100 km digital tile is based on the latest BGS 1:250 000 scale UTM (Universal Transverse Mercator projection) bedrock or ‘solid’ geological map. This series was originally published between 1977 and 1993. Most of the onshore areas were compiled in the 1980s and are based, primarily, on earlier more detailed 1:50 000 (and one-inch to one-mile) geological maps published in the preceding decades and dating from the 1870s through to the 1980s. The source 1:250 000 published maps have a chronostratigraphical classification but were reclassified, as far as possible, with a lithostratigraphical nomenclature for the digital data. Some changes were made to the published lines to correct errors, improve the fit between maps, add formational boundaries or remove purely chronostratigraphical ones. The sources of information specific to each digital tile are available. The generalised geological lines were fitted to topographical bases compiled from Ordnance Survey 1:250 000 maps and Ministry of Defence, Joint Operations Graphic (JOG) sheets. The UTM series sheets were scanned and re-projected to OS British National Grid for digitising. For version 4 (release 2005), the digital data were re-tiled into 100 km squares and re-fitted to the OS Strategi coastline, and RCS (BGS Rock Classificiation Scheme) codes were added.
