Anthracite coal is already a metamorphic rock.
Coal turns into a solid material called graphite when subjected to high heat and pressure over time. Graphite is a crystalline form of the element carbon, with distinct properties such as its lubricating ability and use in pencils.
Yes, under the right conditions of temperature and pressure, anthracite coal can metamorphose into bituminous coal. This process, known as coalification, typically occurs over millions of years and involves the transformation of organic matter in the coal.
It takes millions of years for peat to slowly transform into coal through a process called coalification. Peat is the earliest stage of coal formation and with continued pressure and heat over time, it can progress into lignite, then sub-bituminous coal, bituminous coal, and finally anthracite coal.
The five steps of coal formation are: Peat formation: Plant material accumulates in wet environments. Lignite formation: Compression and heat turn peat into lignite, a soft coal. Sub-bituminous coal formation: Further compression and heat transform lignite into sub-bituminous coal. Bituminous coal formation: Continued heat and pressure convert sub-bituminous coal into bituminous coal, a higher quality coal. Anthracite coal formation: The highest level of metamorphism forms anthracite coal, a very high-quality and hard coal.
Coal goes through several phases before it forms a diamond. First, it undergoes burial and becomes peat. Over millions of years of high pressure and heat, peat transforms into lignite, then into bituminous coal, and finally into anthracite coal. If the conditions are right, further heat and pressure can turn coal into graphite and eventually into diamond.

The rock that gets heat+pressure to turn into a metamorphic rock.
metamorphic rock.....
A metamorphic or Igneous rock
metamorphic
Metamorphic rock
Extrusive igneous rocks can turn into metamorphic rocks through the process of regional metamorphism, where they are subjected to high temperatures and pressures deep within the Earth's crust. This causes the mineral composition and texture of the rock to change, resulting in the formation of a new metamorphic rock.
Melting.
no it can't
yes. it can turn into either one
no, it can't
