NATURAL RESOURCES- Coal

The Carboniferous on Arran does not contain the abundance of coal that is seen on the mainland in rocks of this age. However, at Laggan the Limestone Coal Group of the Carboniferous does contain coal, and this was mined on the foreshore near Cock Farm towards the end of the eighteenth century. The scale of production must have been very small, with estimates of the extracted coal seam being no more than two and a half feet thick. The coal was chiefly mined for the manufacture of salt in salt pans located in the same area, as well as being mined for the burning of limestone.
