What are the different types of coal? PDF version. 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.
Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semianthracite, semibituminous and subbituminous. the anthracite is the oldest coal from a geological perspective.
