What are the types of coal? | U.S. Geological Survey
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …

Coal explained
Coal takes millions of years to form. Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.

The Types of Coal: Composition, Usage, and Energy Value
Coal releases thermal energy or heat when it is burned, along with carbon and ash. Ash is made up of minerals such as iron, aluminum, limestone, clay, and silica, as well as trace elements such as arsenic and chromium. The stored energy potential within coal is described as the "calorific value," "heating value," or "heat content.".
