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.
Foliated rocks are distinguished by their texture, which shows a planar arrangement of mineral grains or structural features such as layering, banding, or alignment of mineral grains. This texture is typically a result of tectonic forces or pressure during the rock's formation, leading to a parallel alignment of minerals. Examples of foliated rocks include slate, schist, and gneiss.
Marble is a non-foliated metamorphic rock, meaning it does not have visible layers or banding. It is formed from the recrystallization of limestone under high heat and pressure.
Some examples of foliated rocks include slate, phyllite, schist, and gneiss. Amphibolite can be either foliated or nonfoliated. Examples of nonfoliated rocks include anthracite coal, hornfels, serpentinite, soapstone, quartzite, marble, and metaconglomerate.
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.
No banding or alignment of a metamorphic rock's minerals would be consider non-foliated.
Foliated rocks have layers in them. We often refer to the layers as Banding.
Foliated textures display visible layering or banding due to the alignment of mineral grains, while non-foliated textures lack this layering and display a more uniform appearance. Foliated rocks typically form under high pressure and temperature conditions, resulting in the alignment of minerals, while non-foliated rocks form under more uniform pressure conditions, leading to a more homogeneous texture.
No, foliated metamorphic rocks have mineral grains that are aligned in parallel layers or bands due to the pressure and temperature conditions during their formation. This alignment gives foliated rocks their characteristic layered appearance.

A metamorphic rock that has grains arranged in bands is said to be foliated. Foliated metamorphic rocks show distinct layering or banding due to the alignment of minerals under heat and pressure during formation. Examples of foliated rocks include schist and gneiss.
Foliated rocks form through regional metamorphism where intense heat and pressure create a banded or layered texture. They can also form through dynamic metamorphism, where deformation causes mineral alignment and banding in the rock.

Marble is a non-foliated metamorphic rock, meaning it does not have visible layers or banding. It is formed from the recrystallization of limestone under high heat and pressure.
Metamorphic rocks can be categorized into two main categories: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while non-foliated metamorphic rocks lack this layered structure.
