Geology of Britain viewer

The Geology of Britain viewer is a simple tool, aimed at the general public, which helps you explore the geology where you live.

The Geology of Britain viewer includes:

• borehole scans
• earthquake timeline
• 3D models

Pan and zoom to where you live, click on an area of interest and reveal the rocks beneath your feet.

Zoom to your area of interest by entering a postcode or place name using the Go to location button.

As you zoom into the map the scale changes from 1:625 000 scale (small scale) to 1:50 000 scale (medium scale).

Move the horizontal transparency slider to darken or lighten the colours of the geological map.

You can also change the basemap to show satellite photographs (Imagery) or various street maps.

Please note that we recommend the GeoIndex onshore or offshore viewers for professional users.
