Download or read book An Australian Phanerozoic Timescale written by Gavin C. Young and published by Oxford University Press, USA. This book was released on 1996 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a new global perspective on the Phanerozoic timescale, by bringing together extensive Australian and overseas research on biostratigraphy, geochronology, and magnetostratigraphy. For the first time, correlations are established between Australian and European biozonal schemes for the entire Phanerozoic, by integrating local and international biozones, isotopic ages, and magnetic polarity intervals. Tie points are based on tightly constrained isotopic and biostrastigraphic ages, and this is the first compilation for the whole of the Phanerozoic to apply results from the latest isotopic dating techniques, including the high resolution ion microprobe (SHRIMP) and variants of the (superscript 40)Ar/(superscript 39)Ar method. These have radically rescaled some parts of the geological column. An Australian Phanerozoic Timescale gives the essential framework for resource exploration, geologic modelling, and reconstruction of past environments and land-sea configurations during the last 545 million years of earth history.

Download or read book AGSO Phanerozoic Timescale 1995 written by P. J. Jones and published by Oxford University Press, USA. This book was released on 1996 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both Wallchart and Explanatory Notes are a compilation of the history and current status of the major subdivisions of the Phanerozoic Eon; they are derived from the detailed charts presented in the larger reference volume, An Australian Phanerozoic Timescale (eds. Young and Laurie, OUP, 1996).The Wallchart displays a linear timescale for the Phanerozoic taken to the level of stages; a non-linear scale for the Precambrian is included to show the fullness of geologic time. The Explanatory Notes describe briefly each time period: its history, definition of its base in terms of isotopic andbiostratigraphic data, and its subdivision into series and stages. AGSO Phanerozoic Timescale 1995 integrates standard European time units and Australian Cambrian and Ordovician stages. This scale is significant for global correlation of Phanerozoic sequences and their biotas. It will be attractiveand useful to resource exploration companies, geological surveys, university and school students, and individual professional and amateur geologists.

Download or read book History of the Australian Vegetation written by Robert S. Hill and published by University of Adelaide Press. This book was released on 2017-03-01 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Australian vegetation is the end result of a remarkable history of climate change, latitudinal change, continental isolation, soil evolution, interaction with an evolving fauna, fire and most recently human impact. This book presents a detailed synopsis of the critical events that led to the evolution of the unique Australian flora and the wide variety of vegetational types contained within it. The first part of the book details the past continental relationships of Australia, its palaeoclimate, fauna and the evolution of its landforms since the rise to dominance of the angiosperms at the beginning of the Cretaceous period. A detailed summary of the palaeobotanical record is then presented. The palynological record gives an overview of the vegetation and the distribution of important taxa within it, while the complementary macrofossil record is used to trace the evolution of critical taxa. This book will interest graduate students and researchers interested in the evolution of the flora of this fascinating continent.

Download or read book Biological Consequences of Plate Tectonics written by Guntupalli V.R. Prasad and published by Springer Nature. This book was released on 2020-11-23 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book recognizes and celebrates the contributions of Professor Ashok Sahni to the field of paleontology. Prof. Sahni established a School of Vertebrate Palaeontology at Panjab University, Chandigarh, India, where he trained many of today’s vertebrate paleontologists of India. The book covers topics on evolutionary patterns, macroevolutionary events, origination and radiation events, changes in physical environments & climate and their implications for biodiversity dynamics, intercontinental affinities and biogeographic connections in a plate tectonic framework. The book begins by exploring India in the age of the dinosaurs, discussing new fossil remains from the Jurassic Era, then moves through the Cretaceous and Eocene to provide a picture on faunal and floral changes in Gondwanaland in the context of plate tectonics. Furthermore, the book explores the evolutionary patterns and biotic dispersals that resulted from the northward drift of Indian plate during the Cretaceous and its collision with Asia in the Eocene. The respective chapters reveal the role of plate tectonics and climate in shaping the geographical distribution of plants and animals in Gondwana, specifically in India, as well as the post-India/Asia collision implications for biodiversity changes and biogeography in the region’s continental environments. Given its scope, the book will appeal to vertebrate paleontologists, evolutionary biologists, and paleobiogeographers.
Download or read book The Permian of Northern Pangea written by Peter A. Scholle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Permian was a remarkable time period. It represents the maximum stage of Pangean continental assembly, includes a major global climatic shift from glacial to nonglacial conditions (icehouse-greenhouse transition), and is ter minated by one of the most profound faunal/floral extinction events in the Earth's history. In addition, Permian oceans, although poorly understood, must have had some quite unique characteristics. Permian seas reached the most extreme values of carbon, sulfur, and strontium isotopic ratios ever achieved in Phanerozoic time, and the isotopic ratios of all three elements abruptly returned to more "normal" values at, or very close to, the Permo Triassic boundary. Finally, the Permian is marked by an abundance of important sedimentary mineral resources. It has large fossil fuel concentra tions (coal, oil, and natural gas), enormous phosphate reserves, and very extensive evaporite deposits, including gypsum, anhydrite, and halite, as well as a variety of potash salts. Study of the Permian has been hampered, however, by a number of factors. These include a scattered geologic literature (presented in a variety of languages), a confusing regional and global stratigraphic framework (based, in part, on inadequate type sections), and largely provincial, often poorly correlatable faunas. All have contributed to the sparsity and inadequacy of overviews of this critical geological interval. The two volumes attempts to bring together some of the widely scattered observations about these fascinating rocks, at least for the northern (pre dominantly nonglacial) parts of Pangea.
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.
Download or read book The Ecology of the Cambrian Radiation written by Robert Riding and published by Columbia University Press. This book was released on 2001 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambrian radiation was the explosive evolution of marine life that started 550,000,000 years ago. It ranks as one of the most important episodes in Earth history. This key event in the history of life on our planet changed the marine biosphere and its sedimentary environment forever, requiring a complex interplay of wide-ranging biologic and nonbiologic processes. The Ecology of the Cambrian Radiation offers a comprehensive and surprising picture of the Earth at that ancient time. The book contains contributions from thirty-three authors hailing from ten countries and will be of interest to paleontologists, geologists, biologists, and other researchers interested in the global Earth-life system.
