  • coal classification Types & Facts Britannica

    The most common classification is based on rank, referring to the degree of coalification that has occurred. The rank of a coal is determined primarily by the depth of burial and temperature to which the coal was subjected over time. With increasing temperature, peat is converted to lignite, a very soft, low-rank coal.

  • What are the types of coal? USGS.gov

    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. Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal
