Geological formations and processes

2floras, inferred primarily from coal bed spore assemblages.Although the above characteristics of Carboniferous strata are presented independently, they are interrelated.When integrated, these characteristics must be consistent with the stratigraphic record.The stops on the trip were selected to illustrate such a consistency.We wish to thank the numerous institutions, agencies, and individuals that contributed to this field guide.The geologic mapping and stratigraphic analysis by Nick Fedorko and Bascombe (Mitch) Blake Jr., West Virginia Geological Survey, were essential to temporal and spatial correlations, and ultimately our paleoclimatic interpretations.Coal petrographic analyses by William Grady, West Virginia Geological Survey, defined petrographic criteria by which domed paleopeat deposits could be distinguished from planar paleopeat deposits.Both field descrip tion and X-ray diffraction studies of probable paleosols by Frank Dulong, U.S. Geological Survey, contributed the interpretations of base level change and pedogenesis.
