Composed of or arranged in thin layers or leaves; having leaves or leaf-like structures; in geology, describing rock with visible layered mineral structure.
From Latin 'foliatus' (having leaves) plus the past participle '-ed,' describing a state achieved through foliation or a natural structure composed of layers.
Foliated rocks like schist and slate split into sheets because minerals crystallized in layers—you can actually peel them apart like stone leaves, which is why ancient peoples used them for roofing!
