| Description: | Oblique aerial view of the island of Ailsa Craig. Looking south towards the north end of the island. The island is a very prominent landmark in the Firth of Clyde formed of a microgranite boss. Ailsa Craig is formed of an arfvedsonite-aegirine-microgranite intruded by vertical dyke swarms of olivine to alkaline olivine-dolerite with basalt margins. Isotopic dating using the Rb/Sr isochron method dates the microgranite at 61.5 Ma. This makes it Tertiary in age. The remains of the castle can be seen on the skyline on the left. It was built on the orders of the Earl of Cassillis by Thomas Hamilton whose coat of arms may be seen on the walls. |
