Committee-EMD Coal
Coal is a solid, brittle, combustible, carbonaceous rock formed by the decomposition and alteration of vegetation by compaction, temperature, and pressure. It varies in color from brown to black and is usually stratified. The source of the vegetation is often moss and other low plant forms, but some coals contain significant amounts of wood.

High-Rank Coal - an overview | ScienceDirect Topics
Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism.Anthracite is shiny black, hard and brittle (see Figure 2.8) and has the highest fixed-carbon content (approximately 86–98%).Due to its low volatile matter (2–12%), anthracites combustion process is slow. Most anthracites have low-moisture content (about 3–6%) and their ...
