BGS GeoSure data is provided as a series of layered themes. Depending on the scale of data chosen, up to five main themes are available.
Example dataset: Edale Valley, Derbyshire.
The upland moorland to the north of the area comprises sandstone and siltstone strata of the Carboniferous Millstone Grit Group. These rest on Carboniferous mudstone, sandstone and shale strata, which are exposed in the valley bottoms and along the southern margin of the sandstone outcrop. To the south of the area the mudstones and shale rest unconformably on massive Carboniferous limestone.
