The 2nd edition of the coal geology volumes includes 600 images relating to exploration, mining, coalbed natural gas (CBNG), and megascopic coal geology. The coal petrology volume includes 489 sets of images pertaining to macerals and minerals in coals.
The geographic coverage of both volumes is worldwide, but with a decided emphasis on the United States (it being the primary base of operation for the compilers for each volume). The examples are provided as somewhat generic examples of geological occurrences, maceral assemblages, etc. and are not meant to imply that a certain example is necessarily typical of all such occurrences from that location, or, in the case of the coal petrology volume, typical of a certain age or rank.
