Caption: Ross of Mull granite, Mull, Argyllshire.
Description: The Ross of Mull granite varies in colour from pale to deep red and is an acid biotite-granite with a little muscovite. British Geological Survey Petrology Collection sample number MC 7337. The texture is coarse and fairly even without prominent feldspar phenocrysts. Several quarries were opened, their position determined by proximity to natural harbours. Ross of Mull granite was used in the construction of Blackfriars Bridge, the Holborn Viaduct and the Albert Memorial in London. Quarrying was last undertaken by the Shap Granite Company and the material was taken out by sea and rail to Westmorland to be polished.
