Sandstone is an sedimentary rock composed mainly of feldspar and quartz and varies in colour (in a similar way to sand), through grey, yellow, red, and white.
Sandstones are often relatively soft and easy to work which therefore make them a common building and paving material.
The principal mechanism for the formation of sandstone is by the sedimentation of grains out of a fluid, such as a river, lake or sea.
The Old RedSandstone is a rock formation of considerable importance to early paleontology.
Found in Wales and Scotland, in England where it borders those two, and in the area around Omagh, Northern Ireland, the Old RedSandstone is a huge set of sedimentary rocks (primarily brown and red, giving it its name) dating to the Devonian.
As a result, the Old RedSandstone is a rich source of marine fossils.
