What is recorded here

The Sound of Iona is a strait separating the Isle of Iona from the mainland of Scotland, characterized by basaltic and metamorphic rock formations. These rocks are part of the Dalradian Supergroup, dating back to the Neoproterozoic to early Paleozoic era (approximately 800 to 500 million years old), and were formed through regional metamorphism and igneous activity associated with ancient mountain-building events. The area is notable for its geological link to the Caledonian Orogeny and its proximity to historically and culturally significant sites on Iona.
