Formation • The transformation of the vegetable debris to coal takes place in two stages: (a) Biochemical or peat stage: During this stage, the plant materials were attacked by various micro organisms. (b) Chemical stage or metamorphism: In this stage, the peat deposit buried under sedimentary deposits lose moisture and volatile components under the effect of high temperature and ...
Coal is a nonclastic sedimentary are the fossilized remains of plants and are in flammable black and brownishblack tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal on the type of plant material, varying degrees of ...
