Bituminous coal is considered a sedimentary rock and therefore would not be foliated or non-foliated, terms which are used to describe metamorphic rock.
Coal is a nonfoliated metamorphic rock. It does not have a planar arrangement of minerals and lacks the distinct layering seen in foliated rocks like slate or schist.
Bituminous coal, or soft coal
Bituminous coal can be used for both metallurgical and steam coal applications. Metallurgical coal is used in the steelmaking process to help create coke, while steam coal is used as a fuel source for generating electricity.
Bituminous coal is a type of coal that is commonly used for energy production and heating. It has a higher carbon content than lignite and sub-bituminous coal, making it a more efficient fuel source. Bituminous coal is known for its relatively high heat content and is often used in industrial processes and electricity generation.
When bituminous coal reacts with vinegar, there is no significant reaction. This is because bituminous coal is mostly carbon in nature and is inert to weak acids like vinegar.

foliated
Marble is non-foliated.
Slate is a foliated metamorphic rock.
Graphite is a foliated metamorphic rock originating from Bituminous Coal.
No. Phyllite is definitely foliated.
Rock salt is not foliated.
Soapstone is a nonfoliated metamorphic rock. It forms from the metamorphism of protoliths such as dolomite or steatite and does not exhibit the characteristic layering or banding of foliated rocks like slate or schist.
Foliated are made of interlocking crystals, non-foliated are not.
Bituminous coal, or soft coal
Foliated and nonfoliated are terms used to describe the texture of metamorphic rocks. Foliated rocks have a banded or layered appearance due to the alignment of minerals, while nonfoliated rocks lack this layered structure and have a more uniform texture.
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.
