Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.

∙ 13y agoCoal deposits that experienced melt due to contact with a magmatic intrusion would become part of the melt mix and would become a part of a body of solidified magma that is either intrusive or extrusive, the exact rock would depend on this and the chemistry of the solidified mineralized mix.

∙ 12y agoNo, most coal is sedimentary rock except anthracite which is metamorphic rock derived from sedimentary.

Is lignite a igneous rock?
Lignite is a kind of coal (brown coal).
What is a rock made from harden molten rock?
Bituminous or anthracite coal, is ignited to create heat.
When lava cools down does it turn into coal?
No, coal is not an igneous rock at all. Coal is made from sedimentary rock that is squeezed under the ground by great pressure.
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.
Coal felsic or mafic?
Neither. The terms mafic and felsic apply to silicate igenous rocks. Coal is neither igneous nor is it composed of silicates. Coal is an organic sedimentary rock.
Is lignite a igneous rock?
Lignite is a kind of coal (brown coal).
Is Anthracite coal igneous metamorphic or sedimentary?
Anthracite Coal is a metamorphic rock.
What is a rock made from harden molten rock?
Bituminous or anthracite coal, is ignited to create heat.
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 example of a extrusive igneous rock is?
coal
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)..
When lava cools down does it turn into coal?
No, coal is not an igneous rock at all. Coal is made from sedimentary rock that is squeezed under the ground by great pressure.
Is coal an extrusive igneous rock?
Coal is not a intrusive igneous rock but is instead a form of Carbon. The carbon is heated and pressured from low grade metamorphism. Coal is formed mostly from marshes or swamps millions of years ago, think of an environment like the everglades in Florida. A igneous rock would be something like a gabbro or granite.
Which type of rock can form deep below surface or above earths surface?
Igneous rock can form deep below the surface as intrusive igneous rock, or on or near the surface as extrusive igneous rock. X Answer is: Igneous
Both diamonds and coal are compressed of carbon but are they both minerals?
No, diamond is a mineral. Coal is an igneous rock; it can take years for coal to form.
Is coal an extrusive or an intrusive?
Coal is a sedimentary rock, except for anthracite, which is metamorphosed coal. Extrusive and intrusive are terms only applied to igneous rocks. Extrusive igneous rocks are solidified from lava at or near the surface, and intrusive igneous rocks are solidified from magma below the surface.
Is coal mafic or felsic?
It is neither mafic or felsic, as these terms refer to the composition of igneous rocks, whereas coal is a sedimentary rock.
