Foliated metamorphic rocks which have layers and banding and non foliated metamorphic rocks which do not.
Is marble a foliated or nonfoliated rock.
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 can be either foliated or nonfoliated.
Some common types of metamorphic rocks that can be found in these two categories are.
Examples of nonfoliated rocks include anthracite coal hornfels.
Examples of foliated metamorphic rocks would be schist gneiss and slate.
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.
Regional contact and cataclastic.
Generally metamorphic rock and the metamorphic processes can be divided into three categories.
Some non foliated rocks include marble amphibolite and quartzite.
Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance.
Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels.
