Conodonts in Ordovician Biostratigraphy
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Archivio istituzionale della ricerca - Università di Modena e Reggio Emilia 1 Conodonts in Ordovician biostratigraphy STIG M. BERGSTRÖM AND ANNALISA FERRETTI Conodonts in Ordovician biostratigraphy The long time interval after Pander’s (1856) original conodont study can in terms of Ordovician conodont biostratigraphic research be subdivided into three periods, namely the Pioneer Period (1856-1955), the Transition Period (1955-1971), and the Modern Period (1971-Recent). During the pre-1920s, the few published conodont investigations were restricted to Europe and North America and were not concerned about the potential use of conodonts as guide fossils. Although primarily of taxonomic nature, the pioneer studies by Branson & Mehl, Stauffer, and Furnish during the 1930s represent the beginning of the use of conodonts in Ordovician biostratigraphy. However, no formal zones were introduced until Lindström (1955) proposed four conodont zones in the Lower Ordovician of Sweden, which marks the end of the Pioneer Period. Because Lindström’s zone classification was not followed by similar work outside Baltoscandia, the time interval up to the late 1960s can be regarded as a Transition Period. A milestone symposium volume, entitled ‘Conodont Biostratigraphy’ and published in 1971, 2 summarized much new information on Ordovician conodont biostratigraphy and is taken as the beginning of the Modern Period of Ordovician conodont biostratigraphy. In this volume, the Baltoscandic Ordovician was subdivided into named conodont zones whereas the North American Ordovician succession was classified into a series of lettered or numbered Faunas. Although most of the latter did not receive zone names until 1984, this classification has been used widely in North America. -

1 Revision 2 2 K-Bentonites: A Review 3 Warren D. Huff 4 Department of Geology, University of Cincinnati, Cincinnati, OH 45221 USA 5 Email: [email protected] 6 Keywords: K-bentonite, bentonite, tephra, explosive volcanism, volcanic ash 7 Abstract 8 Pyroclastic material in the form of altered volcanic ash or tephra has been reported and described 9 from one or more stratigraphic units from the Proterozoic to the Tertiary. This altered tephra, 10 variously called bentonite or K-bentonite or tonstein depending on the degree of alteration and 11 chemical composition, is often linked to large explosive volcanic eruptions that have occurred 12 repeatedly in the past. K-bentonite and bentonite layers are the key components of a larger group of 13 altered tephras that are useful for stratigraphic correlation and for interpreting the geodynamic 14 evolution of our planet. Bentonites generally form by diagenetic or hydrothermal alteration under 15 the influence of fluids with high Mg content and that leach alkali elements. Smectite composition is 16 partly controlled by parent rock chemistry. Studies have shown that K-bentonites often display 17 variations in layer charge and mixed-layer clay ratios and that these correlate with physical 18 properties and diagenetic history. The following is a review of known K-bentonite and related 19 occurrences of altered tephra throughout the time scale from Precambrian to Cenozoic. 20 Introduction 21 Volcanic eruptions are often, although by no means always, associated with a profuse output 22 of fine pyroclastic material, tephra. Tephra is a term used to describe all of the solid material 23 produced from a volcano during an eruption (Thorarinsson, 1944). -

Geobiologie, Goldschmidtstraße 3. 37077 Göttingen, Germany. E-mail: *[email protected] Abstract In this paper we describe four new fossil associations of “reef” and “reef”-like environments of the St. Cassian Formation (Ladinian-Carnian, Dolomites, NE Italy), based on thirty thin sections from 10 “Cipit boulders” olistoliths, which slided from the Cassian platform into coeval basin sediments. The fossil associations were determined by means of microfacies analysis using point-counting and visual estimation, as well as with aid of statistical methods, based on all fractions with a biotic significance (biomorpha and microbialites). Cluster Analyses in Q-Mode were performed, coupling three algorithms and two indices. In all samples, the main components of the framework are microbialite (average of 75%), and macrofossils (average of 20%), whereas cements and allochtonous components, such as allomicrite, do not represent a significant fraction. Based on both microbialite and fossil content, Chaetetid–microencruster Association, Microbialite–microencruster Association, Dual-type Microbialite Association and Microbialite–Terebella Association, were differentiated. -

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in terested institutions and specialists throughout the world.

Proceedings of the Indiana Academy of Science 83 (1993) Volume 102 p. 83-91 CONODONTS FROM COAL BALLS IN THE SPRINGFIELD COAL MEMBER OF THE PETERSBURG FORMATION (DESMOINESIAN, PENNSYLVANIAN) IN SOUTHERN INDIANA Carl B. Rexroad Indiana Geological Survey 611 North Walnut Grove Bloomington, Indiana 47405 ABSTRACT: A well-preserved and moderately diverse conodont faunule was recovered from five coal balls in the Springfield Coal Member of the Petersburg Formation from Peabody Coal Com- pany's Eby Pit, Lynnville Mine, in Warrick County, Indiana. The presence of Neognathodus roundyi and the other species recorded in this study is compatible with the middle Desmoinesian age of the Springfield. Idioprioniodus conjunctus is the most ecologically diagnostic of the conodonts and suggests organic-rich, quiet water with a low pH, which in turn suggests that the conodonts lived in a salt-water marsh bordered on one side by coal swamps and on another by near-normal marine waters. Apparently coal balls had multiple origins, and the origin of the conodont-bearing ones is uncertain. INTRODUCTION Because marine fossils are commonly associated with plant fossils in some coal balls, it is not surprising that conodonts have been reported from them. A half-dozen well-pre- served conodonts from Pennsylvanian coal balls from three different States were figured by Mamay and Yochelson (1962), but no other conodonts were figured; therefore, the overall conodont content in coal balls is unknown. To better understand the distribution of conodonts and their paleoecologic impor- tance in coal balls, samples were processed from coal balls of the middle Desmoinesian Springfield Coal Member of the Petersburg Formation from the Eby Pit of Peabody Coal Company's Lynnville Mine (SW'/4 , SWA, NE'A, Sec.
