Coal-bearing formations underlie about 300,000 square kilometres, almost half of Alberta. In 2014, nine mine sites produced approximately 30.8 million tonnes (Mt) of marketable coal. Subbituminous coal accounted for 78% of the total, metallurgical bituminous coal the remaining 22%. Six surface mines produce subbituminous coal.

Therefore, coal can be found as lignite, subbituminous coal, bituminous coal, or anthracite, which is the final metamorphic stage that contains the highest amount of carbon [39]. However, coal chemistry at its various rank stages is also related to the biopolymers existed in its plants' precursors that have been partially or totally altered via the coalification mechanism [40] .
