✦ Synopsis

Various methods of identifying and classifying macerals are evaluated on the basis of literature references and our own experimental results. Comparison of the diagrams H/C vs O/C, atomic C/H ratio vs weight percentage of carbon, and atomic C/H ratio vs atomic percentage of carbon demonstrates the advantages of the characterization of maceral composition by means of the atomic carbon percentage, which is a function of the content of all five organogenic elements that enter into the composition of the combustible matter of caustobioliths. Illustration by means of maceral analyses from the same seam, of results from pyridine extraction, and of humic acid composition further confirms this view.
