Shale is made of clay-sized particles that have been
compressed and cemented together. 
Shale has a tendency to split in layers and so it is fissile. 
Generally the split surface is more bumpy and irregular
than slate with which it is commonly confused. 
Colors depend largely on iron and carbon content.
