marble and quartzite
Metamorphic rocks that are massive and lack banding include non-foliated types like marble and quartzite. Marble forms from the metamorphism of limestone and is typically composed of calcite or dolomite, while quartzite originates from the metamorphism of sandstone and consists primarily of quartz. These rocks exhibit a uniform texture and structure, making them distinct from foliated metamorphic rocks that show layering or banding.
Lack of banding
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Yes, metamorphic rock that lacks banding is referred to as non-foliated. Unlike foliated metamorphic rocks, which have distinct layers or bands due to the alignment of minerals under pressure, non-foliated rocks have a more uniform texture. Common examples of non-foliated metamorphic rocks include marble and quartzite. These rocks typically form under conditions of high temperature and pressure without significant directional stress.
In subject of metamorphic rocks, to be foliated is to have their grains arranged in parallel layers or bands. Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009
Marble and quartzite are two examples of metamorphic rocks that lack banding and are massive. The lack of banding may indicate that the metamorphism may be due to a greater factor of heat than of pressure.

nonfoliated rocks
Lack of banding
Foliated rocks have layers in them. We often refer to the layers as Banding.
Non-foliated
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
A type of rock with fine banding is known as foliated rock, which includes metamorphic rocks like slate, phyllite, and schist. These rocks have distinct layered structures due to the alignment of minerals during the rock's formation under extreme heat and pressure. The banding in foliated rocks can range from fine to coarse, depending on the intensity of the metamorphic processes.

Certain metamorphic rocks that do not exhibit foliation (banding, lamellar texture) like quartzite and marble are described as non-foliated.
