NJ5866 : Serpentinite

taken 3 years ago, near to Portsoy, Aberdeenshire, Great Britain

The greenish rock making up these two pinnacles is of great interest to geologists. It is serpentinite, made up of a mineral called serpentine, which is formed when rocks with a high Iron-magnesium content are altered by hot fluids circulating in the crust of the Earth. These rocks are originally from the mantle, deep below the crust, and they have been lifted many kilometres to outcrop on the surface. It is this serpetinite that has long been quarried and used as ornamental stone, called (inaccurately) marble, and marketed at Portsoy Marble.
