Which type of metamorphic rock is mined from earth and burned as fuel?
Anthracite coal is a type of metamorphic rock that is mined from the earth and burned as fuel. It is a hard and premium type of coal known for its high carbon content and low impurities, making it a popular choice for heating and energy production.
What is the name of the original rock metamorphic rock?
The original rock that undergoes metamorphism to form a metamorphic rock is called a protolith or parent rock.
Is coal a metamorphic rock?
Coal when subject to mild metamorphism turns into Anthracite, in which the carbon content is between 92% and 98%. If squeezed and heated still further, the coal will transform into graphite and of cause if the taken to extremes diamond will be produced, but that would require the coal to be taken deep into the earth's mantle.
What is a very had rock that burns with a high heat and little smoke a metamorphic rock formed from coal?
Anthracite is a very hard rock that burns with high heat and little smoke. It is a metamorphic rock formed from coal through intense pressure and heat. It is known for its efficiency as a fuel source due to its high carbon content.
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.
What metamorphic rocks is commly known as''coal''?

What metamorphic rock is commonly known as coal?

Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
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.
Is coal metamorphic?
Most coal is sedimentary, but anthracite is bituminous coal that has undergone metamorphosis to become a metamorphic rock.
What is the parent rock for anthracite coal?
Peat (not much of a rock).
Why is coal still a rock?

anthracite
Is coal an igneous rock sedimentary rock or metamorphic rock?
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.
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.
