Amphibolite can be either foliated or nonfoliated.
Is marble a foliated or nonfoliated rock.
Regional contact and cataclastic.
Some examples of foliated rocks include slate phyllite schist and gneiss.
Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance.
Some non foliated rocks include marble amphibolite and quartzite.
The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase.
Generally metamorphic rock and the metamorphic processes can be divided into three categories.
Foliated metamorphic rocks which have layers and banding and non foliated metamorphic rocks which do not.
Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels.
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.
Some common types of metamorphic rocks that can be found in these two categories are.
Examples of foliated metamorphic rocks would be schist gneiss and slate.
