Book Synopsis The Carboniferous Timescale by : S.G. Lucas
Download or read book The Carboniferous Timescale written by S.G. Lucas and published by Geological Society of London. This book was released on 2022-04-26 with total page 1012 pages. Available in PDF, EPUB and Kindle. Book excerpt: The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.

Book excerpt: This trip backward in time capsulizes in a general way the geologic development of the area that is now northern Alaska. The Cretaceous through Recent history is predominantly one of erosion of the ancient Brooks Range and filling of the Colville Geosyncline under processes like those in Operation today. All the rocks older than Jurassic, however, were deposited far from their present sites. One of the intriguing tectonic puzzles involves the geographic positions and relative timing of events that occurred during the orogeny that built the Brooks Range. I suggest that pre-Cretaceous deposition took place far to the north along the western margin of the Caledonides. Subsequently, the region that is now northern Alaska moved southward and impinged upon a northward moving plate, or plates, from the Pacific region. Interactions between these two major parts of the earth's crust produced the Brooks Range during the Jurassic. Later developments reflect continuing readjustments of the northern third of of thrust Alaska as southward movement was dissipated in diverse systems faulting and lateral displacement. ACKNOWLEDGMENTS I am indebted to many colleagues who, during the past 30 years, shared with me the excitement and pleasures of exploring the geology of northern Alaska. Among these are W. P. Brosge, H. N. Reiser, R. L. Detterman, A. K. Armstrong, A. L. Bowsher, E. G. Sable, I. L. Tailleur, C. G. Mull, M. D. Mangus, A. H. Lachenbruch, M. C. Lachenbruch, R. L. Morris, C. J.

Available in PDF, EPUB and Kindle. Book excerpt: Prior to the 3rd International Symposium on Fossil Algae, held in Golden, Colorado in August of 1983, a 3-day fieldtrip concentrating on Recent algal distribution in southern Florida was led by Robert N. Ginsburg and his associates from Miami. A post-symosium fieldtrip to the West Texas-southern New Mexico region was led by Don Toomey and Jack Babcock. This fieldtrip examined Precambrian and Paleozoic algal carbonates in a region characterized by superb outcrop exposures, and included the famous Permian Reef complex. The Toomey-Babcock fieldtrip resulted in a unique fieldguide published by the Colorado School of Mines (1983), and issued to all participants of the symposium. The symposium itself was held from August 15 through Augsut 17 on the campus of the Colorado School of Mines where Professor J. Harlan Johnson, to whose memory this volume is dedicated, spent so much of his career studying fossil algae. The symposium sessions were held for 3 days, and during that time 40 papers were presented and discussed. A I-day fieldtrip, led by John L. Wray, to examine Late Paleozoic phylloid algal carbonates exposed in the nearby Rocky Mountains, concluded the formal meetings.
