Metamorphic rocks are classified as being foliated or being non-foliated. Foliated metamorphic rocks have visible banding or sheet-like layering. Slate, phyllite, gneiss, and schist are foliated metamorphic rocks. Non-foliated metamorphic rocks do not display banding or layering. Marble and quartzite are non-foliated metamorphic rocks. Metamorphic rocks can also be classified as either regional metamorphic rocks or contact metamorphic rocks, depending on their method of formation.
They classify metamorphic rocks according to their parent rock or protolith.
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.
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.
Metamorphic Rocks
Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.

The three main categories into which geologists classify rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and lithification of sediments. Metamorphic rocks are created from the alteration of pre-existing rocks due to high temperature and pressure.

Scientists classify rocks into three main categories - sedimentary, igneous, and metamorphic - based on how they are formed. Sedimentary rocks are formed from the accumulation and solidification of sediments, igneous rocks are formed from the cooling and solidification of magma or lava, and metamorphic rocks are formed from the alteration of existing rocks through heat and pressure.

They classify metamorphic rocks according to their parent rock or protolith.
Scientists classify rocks based on their mineral composition, texture, and how they were formed. These classifications help geologists understand the history and properties of rocks. There are three main categories for classifying rocks: igneous, sedimentary, and metamorphic.
The rock cycle classifies rocks into three main categories: igneous rocks, formed from the solidification of molten rock; sedimentary rocks, formed from the compaction and cementation of sediments; and metamorphic rocks, formed from the alteration of existing rocks through heat and pressure.
