This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Successions of carbonate to mixed carbonate/siliciclastic rocks of Middle Ordovician age were deposited in New York State and Ontario, Canada on the passive edge of the westward advancing Taconic foreland basin. The transition from carbonate to siliciclastic sedimentation is thought to record the critical change from a passive to active tectonic margin. In addition to tectonic change, it has been suggested that this stratigraphic interval also records an overall transgressive series (Tippecanoe megasequence Sloss, 1963) which is interrupted by shorter duration sea-level fall events (Holland & Patzkowsky, 1996, 1998). Holland & Patzkowsky (1996, 1998) delineated 6 sequences for the Mohawkian and correlated these sequences in the southern Appalachians, Nashville Dome, and Cincinnati Arch. However, the succession in New York and Ontario have not been equally evaluated within this framework. Herein, the upper Black River to lower Trenton groups are investigated in order to help understand the event and cyclic stratigraphic relationships of units recognized throughout the outcrop belt from southern Ontario, Canada, to northern New York State and to place these rocks into a sequence stratigraphic framework. Through the use of correlated event beds including K-bentonites, and other marker horizons it has been possible to delineate a series of 2 depositional sequences, with distinctive systems tracts, and small-scale parasequences (or PACs) that are correlatable across the New York-Ontario region. By establishing these correlations it has been possible to provide objective criteria for defining a new position for the Black River/Trenton Group lithostratigraphic boundary in this region, such that it also represents a significant chronostratigraphic boundary as well. In addition to establishing local to regional correlations, through the association of K-bentonites it has also been possible to infer the positions of two of Holland and Patzkowsky's (1996) sequences in the study region. Although the association of Holland and Patzkowsky's M4 and M5 sequences is preliminary, several key issues are raised that support the need for a revision of the North American chronostratigraphic nomenclature as applied outside the New York/Ontario type region.

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.
