Apstrakt

Cancels and replaces the first edition (1984). Specifies a method of determining the proportions of the maceral groups (and the minerals if desired) in coals. Concerned only with determinations made on polished particulate blocks using reflected white light. Not concerned with the determination of the proportions of naturally occurring maceral associations.
