COALIFICATION MICRO-ENVIRONMENTS AND DIFFERENTIAL COALIFICATION OF DESMOCOLLINITES

The desmocollinites occured inspectively in and around the iron sulfide concretions in the same sample showed the differential characteristics of both reflectance and composition,which suggested that there exsited the differential coalification between the same kind of the coal macerals in the same sample as the results of the difference of the coalification micro-environments such as the stress micro-field and the catalyzation from same organic elements.
