Members of the Arran Historical Society are pictured in Lochranza enjoying the scenery and learning about Hutton’s Unconformity.
Arran Historical Society members recently enjoyed a guided tour of Hutton’s Unconformity during a field trip to Lochranza which was attended by 24 members, writes Hugh Brown.
Meeting at the Lochranza Field Centre on a bright spring day, the guides directed the group along the shore, stopping on the way to see the metamorphic rocks of Dalriadian age. These were formed approximately 500 million years ago.
