What else can I help you with?
When mineral grains in a metamorphic rock do not form layers the rock has what texture?
no texture
Where is Anthracite rock found mostly and why?
In metamorphosed coal deposits, usually in mountain forming regions.
Is coal extrusive igneous rock?
No, coal is a sedimentary rock composed mostly of the remains of ancient vegetation (except for anthracite coal which is a metamorphic rock, see image above)..
What texture does and extrusive igneous rock have?
fined grain texture
What can anthracite be classified as?
Anthracite is a type of coal.
What is the texture of anthracite?
Anthracite is a form of coal. It is hard black and shiny.
Is anthracite an igneous metamorphic or sedimentary?
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
What coal has a hard brittle texture?
Anthracite coal has a hard and brittle texture. It is the highest ranking type of coal and is known for its high carbon content and low moisture content.
Is Anthracite coal igneous metamorphic or sedimentary?
Anthracite coal is a type of metamorphic rock. It forms from the transformation of bituminous coal under increased temperature and pressure over time.
Metamorphic rock formed from coal?
anthracite
Is anthracite a sedimentary rock?
No it is not but bituminous coal is
What metamorphism does coal produce?
Coal undergoes low-grade metamorphism, transforming into a type of metamorphic rock known as anthracite. This process involves the heating and pressurizing of coal over millions of years, resulting in a higher carbon content and a more compact, harder texture compared to the original coal.
What is a metamorphic rock commonly known as coal?
Anthracite
Is coal a igneouse rock?
No. It is considered a sedimentary rock, except for the variety anthracite, which is considered a metamorphic rock.
Is anthracite a sedimentary or a igneous rock?
Anthracite is a metamorphic rock, not a sedimentary or igneous rock. It forms from the metamorphism of bituminous coal, under high pressure and temperature conditions deep within the Earth's crust.
What metamorphic rock does anthracite coal turn in to?
Anthracite coal, a type of coal with a high carbon content and low impurities, can turn into metamorphic rock called graphite under high heat and pressure. Graphite is a soft, crystalline form of carbon that is a good conductor of electricity.
