The vitreous appearing components of coal, which in thin section are shown to have been derived from the woody tissues of plants--such as stems, limbs, branches, twigs, roots, including both wood and cortex--changed and broken up into fragments of greatly varying sizes through biological decomposition and weathering during the peat stage, and later flattened and transformed into coal through the coalification process, but still present as definite units.
