Foliated are made of interlocking crystals, non-foliated are not.
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.
a banded texture
The classes of metamorphic rocks include foliated rocks, which have a layered or banded appearance due to the alignment of minerals, and non-foliated rocks, which lack a layered structure. Foliated rocks include slate, schist, and gneiss, while non-foliated rocks include marble and quartzite.
foliated and nonfoliated
Foliated or non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this feature.
At varying depths under the surface.
Examples of non-foliated metamorphic rocks are quartzite and marble.
A banded texture
Coal is a nonfoliated metamorphic rock. It does not have a planar arrangement of minerals and lacks the distinct layering seen in foliated rocks like slate or schist.
Nonfoliated metamorphic rocks do not have a layered or banded appearance like foliated rocks. Instead, they exhibit a uniform texture and lack the alignment of minerals seen in foliated rocks. Nonfoliated rocks are typically composed of minerals that have recrystallized without forming distinct layers.
A non-foliated texture is cataclastic: the result of mechanical fracturing of rocks by the application of directional strain. The texture is chararcterised by the presence of brecciated and bent minerals and rock fragments.
