Abstract:
Ninety-eight samples were collected for this study at 85 localities in 12 Indiana Counties. Percentage relationships of miospore genera and relative abundances of species were determined for these samples and can be used successfully in correlating coal beds within the Pottsville series (Pennsylvanian System).
Two formations, the Mansfield and the Brazil, constitute the Pottsville Series in Indiana. Miospore analysis revealed seven distinct spore assemblages for samples of coals from the Mansfield Formation and indicates the need for further detailed study of these coals. Samples from the Brazil Formation displayed eight distinct assemblages. These spore patterns are useful for dividing the Brazil Formation into eight zones and indicate that the formation may have more coal seams than geologists have previously thought.
