WebRocks that have undergone metamorphism and deformation will likely have a foliation that is not perfectly parallel. This is because the deformation will have caused the rock to flow, and the foliation will be parallel to the direction of flow. Foliated rocks are often used in construction and engineering applications because of their strength ...
