National Bedrock Fence Diagram of Great Britain (GB3D_v2014)
In 2011 the British Geological Survey (BGS) decided to begin the assembly of a National Geological Model (NGM) from its existing and on-going geological framework models , comprising integrated national crustal, bedrock and Quaternary models. The bedrock component is the most advanced of these themes and comprises both the calculated models and a complementary network of cross-sections that provide a fence diagram for the bedrock geology of Great Britain. This fence diagram, the GB3D_v2014 dataset is available in a variety of formats from the BGS website www.bgs.ac.uk as free downloads, it supercedes the earlier 2012 version. The model complements the existing 1:625 000 scale mapsheets published by BGS utilising the same colour schema and geological classification. The component cross-sections extend to depths between 1.5 and 6 km; they have an aggregate length of over 25,000 km, and they are snapped together at their intersections to ensure total consistency. The sections are based on the existing BGS geological framework models where they cut through them together and incorporate around 300 deep stratigraphic boreholes across England and Wales. The sections also take account of the vast wealth of published data on the subsurface structure of Britain both from BGS and in the scientific literature. Much of this is in the form of cross-sections, contour maps of surfaces, and thicknesses (isopachs). The fence diagram has been built in the Geological Surveying and Investigation in 3D (GSI3D) software. It is envisaged that this dataset will form a useful educational resource for geoscience students and the general public, and also provide the bedrock geology context and structure for regional and catchment scale studies. The fence diagram has been built in stages between 2009-14 using funding from the BGS National Capability Programme the Environment Agency of England and Wales, and the Nuclear Decommissioning Authority. Some 16 expert regional geologists compiled the sections.

The fence diagram has been frozen in July 2014, it is anticipated that it will be enhanced further in terms of detail and depth in future years. Probably updated every two years and released as new versions. We recommend that this dataset should be used for general and geoscience education to illustrate of national and regional bedrock geology of Great Britain (from the available download), Illustrating national or regional bedrock geology overviews for scientific publications for widespread and/or non specialist use and regional GIS projects including the extents (x,y) of individual geological units (generated for GIS in GSI3D). We recommend that this dataset should not be used for Detailed geological assessments of any kind, e.g. borehole, site or linear route prognosis, resource-reserve estimation and exploration of any kind and any representation or use outside the intended regional to national (250K-1M) resolution.

The initial fence diagram build in 2009-10 was funded by the Environment Agency of England and Wales (EA). This phase of the development comprised 41 cross-sections with a total linear length of 5,500 km confined to England and Wales. In 2011 this initial network was extended to Scotland, and the earlier coverage was densified. Additional sections were also aligned along the coast to bound the coverage and provide the easily recognisable outline of Great Britain paving the way for offshore expansion of the model. Sections in northern Scotland were continued across the Minch to the Outer Hebrides and similarly to Orkney but at present Shetland has not been incorporated. In 2012, with further funding from the EA, a few additional sections were inserted into the framework for England and Wales, whilst others were extended in length or deepened in key sedimentary basins. This enhancement comprised part of a study to provide a risk screening tool for the EA to help them gauge possible impacts of shale gas extraction on aquifer security. In 2013-14 the fence was extended further in England and Wales by the realignment of some sections to around 300 deep stratigraphic boreholes using funding provided by the Nuclear Decommissioning Authority.
