Sheet working of rock outcrops in the upper part of Drinneevar Quarry

Granite is often fractured into sheets, or "beds", that lie more or less parallel to the surface of the ground. Most sheets exposed at the surface are a foot or less in thickness; deeper down they increase in thickness. Sheeting is generally attributed to upward and sideways expansion of the granite as the overlying Silurian measures were gradually eroded away.
