| Locharbriggs Sandstone | Locharbriggs Sandstone was sourced from a cluster of quarries around the town of Locharbriggs, in Dumfriesshire. The stone consisted originally of wind-blown sand that was deposited as sand dunes in a desert environment during the Permian Period (c. 285 million years ago), when Scotland was at roughly the same latitude as southern Ethiopia is today. A tiny proportion of iron, which is in an oxidised (‘rusted’) state, gives the stone a rich orange colour. Locharbriggs Sandstone has been used locally, regionally, nationally and internationally, mainly to form masonry. Today, Locharbriggs Sandstone is extracted for building stone at one quarry. | Locharbriggs Sandstone — Building Stone Database Scotland (bgs.ac.uk) | |
