Types of shale
Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. Shale is the most common sedimentary rock. The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile … See moreFour common types of foliated metamorphic rocks, listed in order of metamorphic grade or intensity of metamorphism are slate, phyllite, schist (pronounced “shist”), and gneiss (pronounced “nice”).

However, variations in the type and degree of cementing agents cause sandstones to vary from hard, competent rock, to soft poorly cemented material. Sandstones are found in a broad arc across the northwestern and central parts of the state. Shale is formed in a process similar to that of sandstone, but deposition occurred further away from the ...
