Rock, limestone and clay production

Rock has been the mainstay of the quarry industry. It has been especially dominant during booms in the construction of roads, dams and buildings. Clay has declined in importance over time with the closing of brickworks and the fall of the ceramics industry. Limestone is still important being used mainly for agriculture and the manufacture of cement.
