iHydrogeology shale and aquifer surfaces (vertical separation maps and data)

These maps provide an overview, at the national scale, of the spatial relationships between principal aquifers and some of the major shale and clay units in England and Wales. The data comprises a series of occurrence maps shows the distribution of rock units that form the principal aquifers and some major shale and clay units in England and Wales. In addition, a series of separation maps show the vertical separation between pairs of shales or clays and overlying aquifers. If shale gas resources are to be developed in the UK, the implications for groundwater will need to be considered as part of any risk assessment. A step in such an assessment will be to understand and quantify the spatial relationships between the potential shale gas source rocks (including both shales and some clay units) and overlying aquifers. The datasets used to produce the aquifer maps, the shale and clay occurrence maps and the separation maps are available to download for your own use. As with other BGS data sets available for download, this will enable you to work offline to develop your own systems and methodologies using BGS data. The data used to produce the aquifer, shale and clay maps are available below as ESRI GIS and KML files.

Supplemental Information
These surfaces have been developed by the British Geological Survey as part of the iHydrogeology project (a co-funded project between BGS and the Environment Agency). It was developed, in partial fulfilment of work package 3 of the iHydrogeology project, with the aim of providing a tool to visualise regional-scale spatial and depth relationships between Principal Aquifers in England and Wales and potential shale gas source rocks.

Statement
The original surfaces were derived from the National Geological Fence Model. Data from crossections was extracted and interpolated in order to create the surfaces. The top surfaces of the shale gas source rocks were produced from the GB 3D fence diagram (v2012) using GSI3D and GOCAD software. The top of the shale gas units were identified from the cross-sections and grouped based on information provided by Geologists, e.g Upper Jurassic Clays. The cross-section correlation lines from the sections were exported as pline files from GSI3D and imported into GOCAD. Using a combination of the DigMap 1:625 000 Bedrock Map (V5) to constrain the units at outcrop and the correlation points from the GB 3D cross-sections, surfaces were generated using the Discrete Smoothing Interpolation in GOCAD. The subcrop was constrained by the spatial extent of these units identified in cross-section. Surfaces were exported and converted to ESRI grids at 3000 m cell size.
