In addition, the terms used for various coal ranks vary from country to country. Coal may be classified in rock types (or lithotypes) based on the presence of petrological components known as macerals. Based on maceral content and its appearance in a hand specimen, coal is classified into four principal types: clarain, durain, fusain, and vitrain.

What Are the Four Stages in Coal Formation? | Reference.com

The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.

What are the different types of coal? | American ...

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.

High-sulfur coal contains a lot of pyrite, which is a mixture of sulfur, iron, and traces of other minerals. As long as it is underground, this mixture causes no environmental problems. But when it is exposed to air through mining, the pyrite rusts and forms sulfate salts on the coal's surface that can contaminate water.
