Geological Survey maps, 1840s-1940s

National geological map series by the Geological Survey.

We have scanned all our out-of-copyright holdings of geological maps of England, Scotland and Wales. This includes a detailed set of six-inch to the mile maps, focusing just on areas with economically valuable geology, as well as less detailed one-inch to the mile maps. There are also a set of Horizontal and Vertical Sections for areas in Scotland.
