Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.
No, coal is not an igneous rock. Coal is a sedimentary rock that forms from compacted and altered plant material in swampy environments over millions of years, whereas igneous rocks form from the cooling and solidification of magma or lava.
Coal 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.
No. It is considered a sedimentary rock, except for the variety anthracite, which is considered a metamorphic rock.
No, most coal is sedimentary rock except anthracite which is metamorphic rock derived from sedimentary.

Is lignite a igneous rock?
No, lignite is not an igneous rock. Lignite is a type of coal formed from compressed peat. Igneous rocks are formed through the solidification of molten magma or lava.
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.
What is a rock made from harden molten rock?
A rock that is formed from hardened molten rock is called an igneous rock. Igneous rocks can be formed from the cooling and solidifying of magma or lava. Examples of igneous rocks include basalt, granite, and obsidian.
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.
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 lignite a igneous rock?
No, lignite is not an igneous rock. Lignite is a type of coal formed from compressed peat. Igneous rocks are formed through the solidification of molten magma or lava.
Is coal an extrusive igneous rock?
No, coal is not an extrusive igneous rock. Coal is a sedimentary rock formed from the remains of plants that lived millions of years ago. Extrusive igneous rocks are formed when magma cools and solidifies on the Earth's surface.
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.
What is a rock made from harden molten rock?
A rock that is formed from hardened molten rock is called an igneous rock. Igneous rocks can be formed from the cooling and solidifying of magma or lava. Examples of igneous rocks include basalt, granite, and obsidian.
Is coal an igneous rock sedimentary rock or metamorphic rock?
Coal is a sedimentary rock. It forms from the accumulation of plant material that is buried and subjected to heat and pressure, eventually transforming into coal.
Is bituminous coal igneous sedimentary or metamorphic?
Bituminous coal is a type of sedimentary rock that is formed from the accumulation and compaction of plant material over millions of years. It is not igneous or metamorphic in nature.
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.
What type of rock is coal?
Coal is not a rock; it is a black or brown sedimentary rock that forms from partially decayed plant matter. It is classified as an organic sedimentary rock rather than an igneous or metamorphic rock.
Is coal mafic or felsic?
Coal is neither mafic nor felsic, as these terms are typically used to describe igneous rocks based on their silica content. Coal is a sedimentary rock that forms from the accumulation and burial of plant material.
Is graphite igneous sedimentary or metamorphic?
Graphite is a metamorphic rock. It is formed from the metamorphism of organic sedimentary rocks, such as coal, under high temperature and pressure.
