The reason we discussed these groups is that slate belongs to one of them. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. The Inuit used slate to make blades for ulus, a multi-purpose knife. It is the finest grained foliated metamorphic rock. In the early stages of slate's composition, mica sediments were compacted and water was forced out of the clay, forming shale. Different types of rocks have different properties.
