Limestone Coal Formation Sandstone

Limestone Coal Formation Sandstone was sourced from numerous quarries in many parts of central and southern Scotland, including Ayrshire, Dunbartonshire, East Lothian, Edinburgh, Fife, Glasgow, Lanarkshire, Midlothian, Peeblesshire, Renfrewshire, Stirlingshire and West Lothian. The stone consisted originally of sand that was deposited by rivers during the early part of the Carboniferous Period (c. 329 million years ago), when Scotland was at roughly the same latitude as southern Ethiopia is today. Limestone Coal Formation Sandstone was used locally and regionally, mainly to form masonry but also for other purposes including paving and furnace hearths. Limestone Coal Formation Sandstone is not quarried for building stone today.
