How is anthracite coal formed?
Understand the Problem
The question is asking about the process of formation of anthracite coal, which is a high-grade coal known for its carbon content and energy output. This question seeks an explanation of the geological and chemical processes involved in the transition from peat to anthracite.
Answer
Anthracite coal forms when bituminous coal undergoes very low-grade metamorphism and structural deformation.
Anthracite coal forms when bituminous coal undergoes very low-grade metamorphism and structural deformation.
Answer for screen readers
Anthracite coal forms when bituminous coal undergoes very low-grade metamorphism and structural deformation.
More Information
Anthracite is the highest rank of coal characterized by its high fixed carbon content and the fewest impurities.
Tips
Confusing anthracite coal formation with other types of coal formation processes, such as lignite or bituminous coal, which involve different grades of metamorphism and conditions.
