What are the different types of coal? | American Geosciences Institute

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...

The Differences between Bituminous Coal and Anthracite Coal

In general, anthracite is harder than bituminous coal. This is because it contains more carbon.
