1:250 000 Geological Maps (UTM Series)

Geological maps for some parts of the United Kingdom are available at smaller scales than the main 1:50 000 geological maps.

Maps in this series show three sorts of geological information:

• Solid 'bedrock' geology (S)
• Quaternary or 'drift' geology (Q)
• Sea-bed Sediments (Ss)

These are usually presented as separate sheets, although sea-bed sediments and Quaternary geology, or sea-bed sediments and solid geology may be shown on the same sheet. Other data may also be shown as figures or diagrams.

Quaternary geology maps provide information for offshore areas only; onshore territory is not covered unless otherwise stated.
