| Corncockle Sandstone | Corncockle Sandstone was sourced from quarries around the town of Lochmaben, in Dumfriesshire. The stone consisted originally of wind-blown sand that was deposited as sand dunes in a desert environment during the early part of 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. Corncockle Sandstone has been used locally, regionally and nationally, mainly to form masonry. Corncockle Sandstone is not quarried for building stone today. | Corncockle Sandstone — Building Stone Database Scotland (bgs.ac.uk) |
