The objective of proximate analysis indicates the percentage by weight of the Fixed Carbon, Volatiles, Ash, and Moisture Content in coal. The amounts of fixed carbon and volatile combustible matter directly contribute to the heating value of coal.
1 Coal is made of compressed plant debris and thus is a biochemical rock. However, since coal is often found interlayered with clastic rocks, we'll discuss coal with the clastic rocks.  Carbonate rocks include limestone, which is made of calcite (CaCO3), and dolostone , which is made of dolomite (CaMg(CO3)2).
