Metamorphic rocks with a layered or banded look are referred to as foliated.

Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.

The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.

Foliated and nonfoliated are terms used to describe the texture of metamorphic rocks. Foliated rocks have a banded or layered appearance due to the alignment of minerals, while nonfoliated rocks lack this layered structure and have a more uniform texture.

When a metamorphic rock exhibits a layered or banded appearance, it is said to exhibit foliated texture. This texture is a result of the alignment of mineral grains or the presence of alternating light and dark layers. Examples of foliated metamorphic rocks include gneiss and schist.
Metamorphic rocks with a banded or striped appearance are called foliated rocks. These bands or stripes are formed due to the alignment of mineral grains or the presence of alternating layers of different minerals. Examples of foliated metamorphic rocks include gneiss, schist, and slate.
Gneiss, pronounced 'nice', is a coarse grained banded metamorphic rock.
Nonfoliated metamorphic rocks lack a layered or banded structure, unlike foliated rocks. Instead, they typically have a granular or crystalline texture. This texture results from the recrystallization of minerals without the development of preferred orientations, giving the rock a more uniform appearance. Examples of nonfoliated metamorphic rocks include marble and quartzite.
Gneiss is a metamorphic rock that forms from the recrystallization of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded texture and coarser grain size compared to other types of metamorphic rocks.
