Book excerpt: Excerpt from Upper Ordovician Ecology of the Central Appalachians State and regional geologic maps provided the stratigraphic base for the study. The surveys of Butts Cloos Rodgers Stose Gray (1960) and Calver (1963) were supplemented by a number of quadrangle reports dealing with north-central Virginia and southern Pennsylvania. Other central Appala chian literature was surveyed for reference to any previously known exposures of fos siliferous Upper Ordovician rocks. Many of these previously published stratigraphic sections were adequate only in so far as they gave some indication of the overall thick ness of the fossiliferous upper Reedsville strata. The total number of localities visited amounted to more than 200, but fossils were present and collected from only 164. About specimens from these 164 fossiliferous exposures provided the basis for the description of 31 species (and/or genera) that are incorporated into a systematics section at the end of this paper. At over 90 localities fossils were collected from well defined stratigraphic horizons, approximately 35 additional localities served, to some degree, as accurate stratigraphic control; the remaining 40 localities were of more limited value, for the exact order and thickness of the various rock units were not clear at these exposures. In this study data were gathered concerning bedding fea tures, lithologic type and relative abundance of species. Tentative field identifications of both rock and fossil materials were checked in the laboratory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2015-07-27 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Upper Ordovician Rocks of Kentucky and Their Bryozoa Sir: - I have the honor to herewith submit for publication a report on the Upper Ordovician Rocks of Kentucky and their Bryozoa, by Professor John M. Sickles. This is a contribution toward the proper classification of our geological formations, which, as has been stated in another report, is necessary for an intelligent and adequate understanding of their economic values. In order, for example, that we may be able to estimate the depth below the surface at which a known oil or gas-bearing stratum may be found, we must be able to identify the beds seen at the surface and know their relations to other beds in the series of which the oil-beariug stratum forms a member. The identification of particular beds or a groupof bedsiuaseries of stratified rocks largely depends upon a knowledge of their characteristic fossils. There is less general knowledge of bryozoa than of other fossil forms, and yet they are often the only trustworthy means for discriminating some of the minor divisions of a formation series. The Surrey has been fortunate in having the services of Professor Nickles in dealing with that difficult feature of our classification studies, as they relate to the Upper Ordovician or Cincinnatian rocks. The general study of the Cincinnatian series is in the hands of Professor Aug. F. Foerste. His report, which will include many plates, is in course of preparation. It seems well to here notice two suggestions made by Professor Nickles. Calling attention to the fact that the Eden beds are the ones that constitute the least fertile of the Ordovician lands, he suggests that a systematic replanting of timber in the Eden areas would be of exceeding value to the State.

This book was released on 2018-09-22 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geomorphology of the Central Appalachians The number, origin, age, and correlation of peneplains Within the area traversed present a problem concerning Which there is still much difference of opinion. Although a larger number of erosion levels may be represented, the evolution and topography of the Appalachian region will be described With reference to the five most prominent peneplains and to altitudes above and below them. These peneplains, named in the order Of their age, are the pre-triassic, the Fall Zone (jura-cretaceous), the Schooley (tertiary), the Harrisburg (probably late Tertiary), and the Somerville (possibly Pleistocene). The authors hope that this guidebook Will be regarded, not as a statement of facts to be accepted Without question, but merely as a guide to field dis eussions of problems encountered on the journey.

Available in PDF, EPUB and Kindle. Book excerpt: "The Ordovician period is a significant chapter in Earth's history that included the great Mid-Ordovician biodiversification event, the Hirnantian glaciation, and long-term greenhouse conditions. Ordovician rocks are widespread on most continents and the recent finalization of a modern chronostratigraphic classification of the Ordovician system now facilitates high-resolution correlations that allow for integrated multidisciplinary research. The diverse papers comprising this volume address orogenesis, paleogeography, climate modeling, sedimentation, biodiversity, and isotopic excursions; together they promote an integrated view of the Ordovician earth system."--Publisher's description.
