Book excerpt: Excerpt from The Mississippian Pennsylvanian Unconformity in Southern Illinois A systematic study of the mississippian-pennsylvanian unconformity in the southern part of the Illinois basin, using both surface and subsurface data, indicates that many factors were involved in the geologic history of the erosional surface. Criteria are presented for the recognition of the position of the unconformity in the subsurface and the rocks above and below the contact are compared and contrasted. An areal geologic map of the pre-pennsylvanian formations shows three major features: beveling of younger formations at the edges of the Illinois basin; beveling of small structures in the basin; and long, deep, narrow channels as features of the erosional surface. Several isopach maps indicate the configuration of the channel systems and the upland surface between channels. The geologic history of the unconformity started with uplift and withdrawal of the sea in late Chester time followed by a long period of subaerial erosion. A peneplain was formed across beveled minor structures and older Chester and Lower Mississippian formations at the structurally higher basin borders. After peneplanation and a subsequent second uplift a new cycle of erosion began that resulted in the incision of deep channels in the peneplain surface. In early Pennsylvanian time the topography was buried by detritus laid down by aggrading streams which later merged with coarse sediment advancing westward from the Appalachian geosyncline. During and after Pennsylvanian time the unconformity was warped, folded, and faulted to its present attitude. The unconformity between the Mississippian and Pennsylvanian systems is well below ground level throughout the area covered by this paper (fig. Thus only subsurface geologic methods could be used in mapping the unconformity. There are many published descriptions of the unconformity for areas where the mississippian-pennsylvanian contact is exposed; in fact, almost every areal geology report covering such areas in southern Illinois, southern Indiana, and western Kentucky includes some discussion Of the erosional surface, but there has been no integrated regional study Of the outcrops and no detailed study of the unconformity in the subsurface. Field work in the southern part Of the Eastern Interior basin has been helpful to the writer in interpreting the subsurface data.

Jeffrey Over and published by . This book was released on 2009 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Conodonts are extinct chordates resembling eels, known mainly from tooth-like microfossils called elements, found in Late Cambrian to Late Triassic fossil deposits (495 to 200 MYA). The nine manuscripts in this volume were, for the most part, first presented at conferences dedicated to conodont studies in 2006-2007 that each celebrated two milestones in conodont studies, the 150th anniversary of Christian H. Pander's 1856 paper that first described and illustrated conodonts, and the organization of the society for conodont enthusiasts that now bears his name in 1967. These papers cover a wide range of topics, times, and regions, illustrating the broad utility of conodonts, primarily as biostratigraphic tools, but also in studies of, although not limited to, geochemistry, paleobiology, paleogeography, and sequence stratigraphy."--Publisher's website.
