OR/14/050 Modelled volume, purpose and scale

Monaghan, A A. 2014. Model metadata report for BGS - DECC shale study model, central and eastern Midland Valley of Scotland. British Geological Survey Internal Report, OR/14/050.

Figure 1    Extent of the model as illustrated by a map showing the outcrop position of the regional-scale faults included, together with the main structural features, using the base of the West Lothian Oil-Shale unit (in feet) depth map from Monaghan (2014) © DECC.

The modelled surfaces cover the central and eastern areas of the Midland Valley of Scotland with the corner coordinates being approximately SW 238000, 641000 to NE 365000, 722000. The model scale is approximately 1:250 000 and the Z range of modelled surfaces is from +350 to -5870 m relative to Ordnance Datum.

The purpose of the model was to form a regional scale geological framework on which to calculate gross rock and net mature shale volumes. Only the largest, regionally important faults were included.
