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.
