Free geological map viewer
Our Map Library has an almost complete collection of geological maps of Great Britain, many of which are available on four-week loan. However, if one of our maps is out on loan or the sheet you require isn’t yet part of our collection, try the excellent BGS maps portal.
The BGS maps portal allows you to view over 7000 high resolution images of almost all the small and medium scale maps produced by the British Geological Survey. This includes digital facsimiles of all the most recent 1:50,000 scale publications, so this could be handy if you’re desperate to view the horizontal section through your study area but the necessary map isn’t available. The site also includes hydrogeological maps and regional geochemical atlases.
