Abstract

A study of macerated coals from 3 wells in Mississippi which penetrated the Pennsylvanian section indicates that spores, which are potentially useful in correlation from one area to another, can be isolated from regular well cuttings. No definite correlations can be made between the coals from the 3 wells and the outcrop samples from Walker County, Alabama, on the basis of the spore assemblages of the coals chosen for this study, but spores present in the Alabama and Mississippi samples indicate that all the coals are Pottsville in age. The spores present in the lowermost coals of the Young-Henderson well provide information extending the stratigraphic range of several genera farther into the lower Pennsylvanian in North America. This information corresponds in most cases with information published by Potonie & Kremp from Europe and Asia.
