Abstract

A study of the sclerotioids from the two coal seams of Permian age, reveals considerable variation in the petrography and reflectance. Discrete bodies of both chanelled and vesiculated sclerotioids occur characterized by much variation in morphology, hardness, relief, and reflectance. The sclerotioids show the largest reflectance span of all other components of coal. Only those sclerotioids with lower reflectance indicate a slight influence of coalification, which decreases as the reflectance increases.The considerable variation in the properties indicate diverse origin of the sclerotioid bodies with varying response to the process of coalification.
