Description: Quarry at Damheads, 366 m. west by north of Damheads, 2.4 km. south-south-west of Portsoy. Banffshire. Close-up of deep opencast excavations along talc veins. Mass of serpentine left as barriers. Note the pit props used to stabilize the faces. The rock is a variegated foliated serpentine shattered by numerous crushes into large lens-shaped masses coated thickly with white talc. In slice the rock is an olivine-serpentine with wisps of talc along shear-lines. Talc is another hydrated magnesium silicate. Serpentine is also a hydrated magnesium silicate. They occur mainly in altered ultrabasic rocks where they are derived from olivine or enstatite.
