The Borrowdale Volcanic Group (BVG) exhibit ssignificant lateral and vertical variation . It is not practical to represent the whole of the Lake District BVG succession on a single table. In this case a representative section from a specific local area (the Caldera volcano) has been provided. CODES - BGS lexicon .
