Peat Accumulation and Compaction in a Connecticut Coastal Marsh. Acta Geologica Polonica, 58, 455—471. Journal of Microscopy 109, 75—83. Petrographic analyses of 25 coal balls from well-studied paleobotanical profiles in the Middle Pennsylvanian Herrin Coal Westphalian D, Illinois Basin and five select coal balls from university collections, indicate that Herrin Coal-ball peats were permineralized by fibrous and non-fibrous carbonates. Revision of Nomenclature of the Springfield No. In the immediate vicinity of plant cell walls, non-fibrous carbonates cut across fibrous carbonates as a secondary, neomorphic phase attributed to coalification of plant cell walls.,,IBS 5.
