Which process is anthracite coal formed from bituminous coal?
metamorphism
What metamorphism does coal produce?
The metamorphic rock anthracite is metamorphosed coal.
By which process is anthracite coal formed from bituminous coal?
In the US, the anthracite coal seam exists primarily in Eastern Pennsylvania. Across the Appalachian Mountains begins Bituminous coal in the geological area called the Pittsburgh Coal Seam-- - an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Metamorphosis transforms anthracite coal, a hard coal, to Bituminous coal, a soft coal.
What is harder lignite or anthracite coal?
Anthracite coal is harder than Lignite.
What metamorphic rock does anthracite coal turn in to?
Anthracite coal is already a metamorphic rock.
Which process is anthracite coal formed from bituminous coal?
metamorphism
What metamorphism does coal produce?
The metamorphic rock anthracite is metamorphosed coal.
What is the original form of anthracite coal?
Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
What is anthracite used for?
Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
How anthracite forms?
Anthracite, also known as anthracite coal, is formed through metamorphism. Anthracite needs pressure to form, as well temperatures of at least 250 degrees Celsius.
What type of coal has undergone the greatest change?
Anthracite coal has been through low-grade metamorphism to become the highest grade of coal. This type of coal has the highest carbon count and the fewest impurities of any other type of coal.
By which process is anthracite coal formed from bituminous coal?

Metamorphosis transforms anthracite coal, a hard coal, to Bituminous coal, a soft coal.
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 anthracite coal used for?
Anthracite coal is used for steel making.
Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
Is Anthracite coal igneous metamorphic or sedimentary?
Anthracite Coal is a metamorphic rock.
What is harder lignite or anthracite coal?
Anthracite coal is harder than Lignite.
