Caption: Limestone from Portsoy Marble Quarry, Banffshire.
Description: A greenish, streaky limestone with dark grey laminae from the Portsoy Marble Quarry, Banffshire. British Geological Survey Petrology Collection sample number MC 7659. Belonging to the Easdale Subgroup of the Argyll Group of the Dalradian Supergroup the Portsoy Limestone formation contains impersistent bands of limestone that have been worked for many years. Banffshire is one of the highland counties that are richly endowed with limestone and their exploitation for agricultural and other purposes has proceeded for hundreds of years. A key factor in early exploitation of limestones were location of limestones, situated in a prime arable agricultural area, limestones in plentiful supplies in Banff and not generally found in adjacent counties and the high cost of transport from centres of production further south.
