Map Symbols and Lithological Ornaments

The British Geological Survey has brought together in one document (Cartographic standard geological symbol index) a complete listing of all its geological cartographic symbols, linestyles and lithological ornaments in current usage.

They represent a British Standard. The symbols are used at all scales and are independent of ornament and colour. The symbols are indexed by geological classification and by description, and are illustrated by symbol reference name. These reference names are an abbreviated form of their description.

This report represents a revised version (3) of the first phase of a project to make BGS map symbols more widely available.
