Coal Formation [Athro, Limited: Geology: Gubik Trip]

The Coal Formation Process. Coal Formation starts with accumulation of organic matter (bits of dead plants) in a low oxygen setting such as a peat bog. The organic matter accumulates and forms a bed of peat. The peat bed gets buried by other sediments and under heat and pressure begins to transform to a low grade coal a Lignite.

Anthracite 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%), anthracite's combustion process is slow. Most anthracites have low-moisture content (about 3–6%) and their
