Caption: Weathered limestone from Balachullish, Argyllshire.
Description: Limestone from Balachullish weathered to a deep yellow with a honeycomb structure. The yellow will be iron oxide or iron carbonate. British Geological Survey Petrology Collection sample number MC 7549. The rock belongs to the Appin Phyllite and Limestone Formation belonging to the Dalradian Supergroup (Precambrian). This is probably from the distinctive 'tiger rock' which consists of regularly-spaced 5 to 10 cm. layers of deep yellow-weathering dolostone and dark phyllite. Limestones are in plentiful supply in Argyllshire. They occur in the Precambrian, in both the Dalradian, the Loch Tay, Tayvallich, Appin, Shira, Lismore and Islay limestones, in the Precambrian Lewisian such as the marbles on Iona and in the much younger Jurassic of Loch Aline and Ardnamurchan.
