Examples of nonfoliated rocks include anthracite coal hornfels.
Is marble a foliated or nonfoliated rock.
Some common types of metamorphic rocks that can be found in these two categories are.
Amphibolite can be either foliated or nonfoliated.
Foliated metamorphic rocks which have layers and banding and non foliated metamorphic rocks which do not.

Examples of foliated metamorphic rocks would be schist gneiss and slate.
The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase.
Amphibolite argillite cataclasite eclogite gneiss greenstone hornfels marble migmatite mylonite phyllite and schist.
Some non foliated rocks include marble amphibolite and quartzite.
