NG5636 : Oolitic Limestone

taken 6 years ago, near to Inverarish, Isle of Raasay, Scotland

Oolitic Limestone
Oolitic Limestone
When the ironstone was first worked, it was simply stripped off the surface. At the edge of the stripped area is a low cliff of the remaining limestone. Ooliths are formed in shallow seas, where the movement of the water results in the formation of tiny spheres, which are then deposited and lithified. Most oolitic limestone is calcium carbonate, but the Raasay ooliths contain chamosite, which is an iron silicate. You can see the speckled oolitic surface between the wild violets.
Ironstone Mining on Raasay

Between 1912 and 1916 iron ore was extracted from ironstones that outcrop in the southern part of the Isle of Raasay. Extensive ruins of the workings and associated buildings continue to disfigure the landscape of the island.
