Some common types of metamorphic rocks that can be found in these two categories are.
Is marble a foliated or nonfoliated rock.
Examples of foliated metamorphic rocks would be schist gneiss and slate.
Examples of nonfoliated rocks include anthracite coal hornfels.
Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels.
Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance.
Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance.
Amphibolite can be either foliated or nonfoliated.
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.
Generally metamorphic rock and the metamorphic processes can be divided into three categories.
