Abstract
The definition and nature of coal macerals is presented in terms of some current research. Recent work on the nature of several precursors of the liptinite maceral groups are discussed and compared to the corresponding liptinite macerals. The importance of separating macerals is considered, and some recent results using the density gradient centrifugation method of maceral separation is briefly reviewed. It is demonstrated that vitrinites are complex mixtures, not simple macerals.
