Geological mapping

GSNI has produced a number of geological maps that provide information on the composition of bedrock and superficial deposits at a range of scales:

• 1:250 000
• 1:50 000 (including six inch to one mile series)
• 1:25 000
• 1:10 000-scale field maps and standards (including 1:10 560 series maps)

These products are available in paper and digital format; the latter can be accessed through the GSNI Data Catalogue and GSNI GeoIndex.
