Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 354. One of the great geologic advances of the last 15 years has been increased recognition of global cycles of sea-level change, and their effects on the stratigraphic record and localization of economic products from the earth. Field Trip T354 for the 28th International Geological Congress will demonstrate the geologic effects of Paleozoic sea-level change in the Appalachian basin strata within 300 miles (500 kilometers) of the Congress headquarters site. Figure 1 shows the location of the Appalachian basin and other areas with great thicknesses of Paleozoic strata within the conterminous United States. The Appalachian basin contains one of the most nearly complete Paleozoic stratigraphic sections in North America, and this presents an opportunity for Congress participants to make detailed comparisons with sea-level history in regions more familiar to them.

"Dr. John M. Dennison spent his career studying the Appalachians, teaching and mentoring his students and professional colleagues, publishing papers, leading field trips, and presenting ideas at regional, national and international conferences. This volume is a collection of papers contributed by former students and colleagues to honor his memory. Learn about stratigraphy and paleontology ranging in age from Ordovician to Mississippian in Kentucky, New York, Tennessee, Virginia, and West Virginia; Devonian airfall tephras throughout the eastern United States; a Devonian lonestone; a Middle Eocene bentonite in North Carolina and its relationship to a volcanic swarm in western Virginia; and a 3D model of a ductile duplex in northwestern Georgia. The stratigraphic and geologic diversity of the papers reflect Dennison's many interests and relationships with a large group of geoscientists"--

"This volume summarizes new developments in understanding the longest-lived icehouse period in Phanerozoic Earth history, the late Paleozoic ice age. Resolving the Late Paleozoic Ice Age in Time and Space provides summaries of existing and new data from the various Gondwanan continental relics, and also reviews stratigraphic successions from the paleotropical and temperate regions of Laurussia that preserve an indirect record of glaciation. It addresses the extent to which records of glaciation indicate protracted, long-term climatic austerity, as opposed to fluctuating, more dynamic climate, and provides new constraints on the timing of glaciation. Additionally, it tackles questions of synchroneity of glaciation across the various Gondwanan continental relics, and timing relationships between near-field and far-field records at greater levels of resolution than has been possible previously. Results point toward a dynamic icehouse regime that is comparable to the Cenozoic icehouse, and away from traditional interpretations of the late Paleozoic ice age as a single, protracted event that involved stable, long-lived ice centers."--Publisher's website.

This volume presents results of a variety of case studies documenting the Late Palaeozoic climate changes and cyclicity of deposition. The collected papers cover many aspects related to palaeoenvironmental analysis with sedimentological, stratigraphic, palaeobiological, geochemical, and palaeomagnetic studies of the fossil record around the Late Palaeozoic Ice Age and soon after. They span a stratigraphic interval from Carboniferous to Permian–Triassic transition around the world. This book comprising results for a range of disciplines, is a valuable source for not only researchers who are actively working on specific aspects of the Late Palaeozoic and looking for an up-to-date reference on this inhospitable time in the Earth’s history. It is also of interest to climate modellers and the wider scientific community with an interest in the latest research on the decline of the Palaeozoic World.
