Black Slate

Black Slatestone is a fine-grained metamorphic rock that shows no obvious compositional layering, but can easily be split into thin slabs and plates. It is usually formed by low-grade regional metamorphism of mudrock. This is in contrast to the silky cleaved surfaces of phyllite, which is the next higher grade of metamorphic rock derived from mudstone. The direction of cleavage is independent of any sedimentary structures in the original mudrock, reflecting instead the direction of regional compression.
