Palynological assemblage resemblance in the Croweburg coal of Oklahoma


, : Palynological assemblage resemblance in the Croweburg coal of Oklahoma. Oklahoma Geology Notes 24(6): 138-143

To test and apply to palynology Simpson's (1960) technique, the Croweburg coal, a widely distributed Pennsylvanian seam, was chosen because of its uncertain stratigraphy, remarkably uniform thickness, and well known palynology. This coal shows three stages of spore succession so it is necessary to sample carefully the complete seam at each outcrop. Also, the samples must be processed essentially alike; the lithology of samples should be as nearly identical as possible, and the taxonomy of the fossils in the assemblages must be known. Correlation with the Colchester coal of Illinois shows 21 species in common, or 51.2 percent of the taxa at specific rank, and six species restricted to the two coals.
