Coal: Types and characteristics. Coal is a complex agglomeration of organic and inorganic material originally deposited as a peat bog. The type of coal which is produced from peat is influenced by a number of factors including the final level of maturation (burial) of the coal, type of original vegetation and the degree to which the vegetable ...

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
