Although most plant matter decomposes where it falls, when plant life containing cellulose-rich stems and leaves is highly abundant and special conditions exist, the plant matter does not totally decompose and is preserved in fossilized form. Coal Analysis. Most, if not all, coals are tested prior to being used. Some markets require specific quality characteristics for the process in which the coal is used, and environmental regulations also require knowledge of a coal’s quality. Some products also require analysis of physical characteristics of coals for handling or processing.
