Geological Heritage of County Mayo Exhibition

Mayo's geological heritage spans nearly two billion years of Earth's history. Its coastal regions are home to some of the oldest rocks visible in Ireland. The powerful force of geomorphological and geological processes is visible in the county's landscapes and landforms. Unique exposures of bedrock exhibit well-preserved fossils, minerals and erosional features.

This exhibition is based on the book Reading the Rocks - Exploring Mayo's Geological Heritage, by Prof Martin Feely and Dr Ronan Hennessy.
