: carbon aromaticity; : layers of the microcrystal; : numbers of benzene ring; : size of stacking of basic structural units; : extension of basic structural units; : the spacing among monolayers of aromatics; : the aliphatic spacing; : radical density. Broad horizontal lines in the table distinguish TDCs formed in different metamorphic and deformational environments; narrow horizontal lines distinguish tectonically deformed coals of different deformational series. Parts of Table 3 are the same.
