Glenvale Sandstone Formation

Computer Code: GEF Preferred Map Code: notEntered
Status Code: Full
Age range: Late Devonian Epoch (DU) — Late Devonian Epoch (DU)
Lithological Description: Brown, red, purple, yellow and cream coloured feldspathic sandstone, commonly containing bands of red siltstone and pebbles of silty mudstone, but no siliceous pebbles.
Definition of Lower Boundary: The boundary is gradational, and is drawn at the base of the brown, yellow, red, purple or cream sandstones of the Glenvale Sandstone Formation, where it rests conformably on the red or purple pebbly sandstones of the Burnside Sandstone Formation.
Definition of Upper Boundary: Drawn at the probable conformable upward passage from brown, yellow, red, purple or cream sandstones of the Glenvale Formation to the white or cream sandstones of the Knox Pulpit Sandstone Formation. In the Cupar area, the Dura Den Member intervenes.
Thickness: Up to 350 m thick in the Lomond Hills area.
Geographical Limits: The Fife and Kinross area of the Midland Valley of Scotland, sheets 40, 48 and 49.
