Sapropelic coals are described in terms of such characteristics as proximate analysis, hardness, lustre, petrographic analysis and total organic content (TOC). Sapropelic coals from North America, Europe, Russia, Africa, Asia and Oceania feature in the book. Sapropelic coals have for several centuries been used to make such things as ornaments and statues, and this is discussed in the book with several illustrations. In the coverage of North America the pre-eminence of Kentucky as a source of sapropelic coals is emphasised.
