Mudstone

A species of Sedimentary

This sedimentary rock is unusual for its superfine grains (usually clay or silt) which give it a nearly smooth appearance. Mudstones don’t have many industrial uses, as they tend to be quite soft and breakable. One variety of this stone, shale, can be used decoratively and has also been used as a roofing material for millennia. If you see a stone-tiled roof, there’s a good chance it's made of mudstone!
