This afternoon 🚣‍♂️ rowed😊 to one of the smallest of the old Ross of Mull Granite quarries, at Rudh' nam Buthan, where around 1890, a rather greyish granite was worked to build the Baptist church in Bunessan. The church makes lovely use of this stone, combined with more normal pink Ross of Mull granite, and a basalt from an as-yet-unidentified source. #Mull #RossOfMullGranite #BuildingStones #Quarry

Stones in the wall of blackhouse at Suidhe. A big block of local Moine mica schist has been laid "on edge" so that the mica flakes relfect spectacularly. And below this, a block of Moine psammite containing a distinctive wee pale spotty calc-silicate layer with one dark margin has been broken in half by the builder, and the two pieces used next to each other. One has been rotated so that it is "upside down" relative to the other. #Mull #Bunessan #BuildingStones
