Description
Dunbar is built on a coastal headland or promontory with a complicated geology. Small volcanic necks, igneous dykes and beds of volcanic tuff (now cut into cliffs by wave action) cut through sedimentary deposits that become more obvious to the east and west of the town.
All these rocks are more than 300 million years old.
The distant island is known as the Bass Rock. It is a volcanic plug of phonolitic trachyte rock of Carboniferous (Dinantian) age. The island is host to the largest colony of the Northern Gannett (Morus bassanus).
