dc.description Indiana Geological Survey Report of Progress 4 en
dc.description.abstract In this report the significance of spores in plant life cycles is discussed briefly. The term “miospore” is proposed for fossil spores and spore-like bodies under 200 micra in size. Sampling and coal preparation are outlined, the stratigraphy of the Alleghenian series in Indiana is sketched in broad strokes, and the underlying principles of the theory of coal correlation are discussed. Percentage relationships of miospore genera have been established for the nine known coal seams of the Alleghenian series in Indiana, and some unknown coal beds have been identified on the basis of the relative abundance of certain genera. en
