The integration of high-resolution biostratigraphy with high-resolution chemostratigraphy provides the scaffolding necessary to determine the precise order of events during this interval of Earth’s history. This study includes three separate manuscripts that integrate biostratigraphic and chemostratigraphic data to provide better correlation than either tool could on its own. The second chapter examines a core from the Moose River Basin in Ontario, Canada and utilizes conodont biostratigraphy and carbon (d13Ccarb) isotope chemostratigraphy to constrain the relative age and generate a chronostratigraphic framework for Llandovery (Silurian) strata in this cratonic basin. The integration of conodont biostratigraphy and carbon (d13Ccarb) isotope chemostratigraphy permits rock units that have been studied for more than a century to be correlated. The third chapter examines conodont biostratigraphic and carbon (d13Ccarb) isotope chemostratigraphic data from a core on the southeastern margin of the Algonquin Arch along the distal, northwestern margin of the Appalachian Basin. Data from this study permits the opportunity to correlate lithostratigraphic nomenclature utilized by the Ontario Geological Survey (OGS) and United States Geological Survey (USGS), and allows correlation of these Silurian (Llandovery and Wenlock global series) strata with the Niagaran Provincial Series. The fourth chapter examines the conodont fauna in the Appalachian Basin in central Pennsylvania. The conodont species of this fauna are long-ranging, limiting their utility for global biostratigraphic correlation. Integration of strontium (87Sr/86Sr) isotope chemostratigraphy permits chronostratigraphic correlation of this fauna limiting it to the Middle/Upper Ordovician boundary interval. These chapters together collectively demonstrate the importance of integrating multiple chronostratigraphic tools. Biostratigraphy can provide a unique answer for relative age, but it is often subject to poor yields or regional endemism. Chemostratigraphy does not provide a unique answer for relative age determination, but is not susceptible to poor yields or regional endemism. The integration of biostratigraphy and chemostratigraphy is an optimal tool for global chronostratigraphic correlation. 2014 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1408990404 http://rave.ohiolink.edu/etdc/view?acc_num=osu1408990404 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
