Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).

Metamorphic rocks can be categorized into two main categories: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while non-foliated metamorphic rocks lack this layered structure.
Metamorphic rocks are either foliated or non-foliated. Foliated metamorphic rocks will display banding or layering of its mineral constituents, non-foliated metamorphic rocks will not.
The lithosphere is primarily made up of two types of rocks: igneous and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma, while metamorphic rocks are rocks that have undergone a change in texture and composition due to heat and pressure.
Metamorphic Rocks
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
Metamorphic rocks are classified into two main groups: foliated and non-foliated. Foliated rocks have a layered or banded appearance due to the alignment of mineral grains during metamorphism, while non-foliated rocks lack this layered structure and typically consist of interlocking crystals.
