Cave uphill from Corrie, Arran, showing Permian limestones full of enormous brachiopod fossils.
Mylonite at Corrie Sands, Islay, Scotland
Near Clachtoll, there is a nice groove cut into the 3.0 Ga Lewisian basement and filled with 1.2 Ga breccia at the base of the Clachtoll Formation of the Stoer Group.
The Stoer Group lies below the Torridonian. The unconformity surface here has a lot of relief on it.
Oldest fossils in the United Kingdom.
Unconformity between 3.0 Ga Lewisian gneiss and 1.0 Ga Torridonian siliciclastics.
Unconformable contact between the Lewisian gneiss (3.0 Ga) and the Torridonian Group (1.0 Ga).
Proterozoic siliciclastics. Spot the paleomag drill holes ("research vandalism")
Part of the Cambrian succession exposed north of Loch Assynt. Note the Skolithos trace fossils. Less obvious are small, cone-like Salterella.
