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: Dundee, Scotland.
The area around Dundee is mainly underlain by sandstones, siltstones and mudstones of Devonian age. To the north-west, in the Sidlaw Hills, and to the south-east, along the southern shore of the Firth of Tay, volcanic rocks of similar age crop out. Small outcrops of intrusive igneous rocks occur under Dundee itself and between Dundee and the Sidlaw Hills.
