Shale Rock Facts. Shale is the most common stone found in the sedimentary rock family. It makes up about 70% of the earth’s outer crust. Shale Rocks are commonly referred to as Claystone because they are composed of mud and clay sediments that have accumulated over a long period of time.Claystone - greater than half of the composition is clay-sized particles. Mudstone - hardened mud; a mix of silt and clay sized particles. The difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms.Claystone, hardened clay. Some geologists further restrict the term to a sedimentary rock that is composed primarily of clay-sized particles (less than 1256 millimetre in diameter) and is not laminated or easily split into thin layers; such rocks that show cleavage roughly parallel to the bedding The Meuse\Haute-Marne underground research laboratory: Mechanical behavior of the Callovo-Oxfordian claystone.
