| Description: | North side of Carlingheugh Bay, 3.2 km. north-east of Arbroath, Angus. The barytes vein filling the fault line between the Lower Old Red Sandstone and Upper Old Red Sandstone, (Lower and Upper Devonian respectively). Barytes, (Barium Sulphate BaSO4) is the most common barium mineral, occurring mainly as a gangue mineral in metalliferous hydrothermal veins but as here, in veins or fault-related cavity filling in sandstones. The difference in weathering of the Lower and Upper Old Red Sandstone rocks either side of the fault is clearly visible. |
