  • What Makes Metamorphic Rocks So Unique?

    The presence of mineral layers, called foliation, is an important feature for classifying metamorphic rocks. As strain increases, the foliation becomes more intense, and the minerals may sort themselves into thicker layers. The foliated rock types that form under these conditions are called schist or gneiss, depending on their texture.
