It comes from shale or at least at one time it was shale. So geologists say that shale is the parent rock. It is made up of clay minerals. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure. Schist has a greater degree of metamorphism than phyllite but less than gneiss.

Shale is one of the most common sedimentary rocks. It is composed of silt or clay that has been compacted or squeezed together to form a solid rock. Shale is usually found in thin layers. The silt or clay that composes shale is made of very small pieces of weathered rock. The pieces are from 1/16 to 1/256 of a millimeter in diameter.
