Book Synopsis Early Palaeozoic Biogeography and Palaeogeography by : D.A.T. Harper
Download or read book Early Palaeozoic Biogeography and Palaeogeography written by D.A.T. Harper and published by Geological Society of London. This book was released on 2014-01-27 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.

Book Synopsis Indian Geological Sequences by : Jai Krishna
Download or read book Indian Geological Sequences written by Jai Krishna and published by Elsevier. This book was released on 2024-06-18 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indian Geological Sequences: Salient Features and Major Events focuses on the first ever differentiation of the entire Indian record into a five tier hierarchical succession of geological sequences – five giga to 12 mega to 25 1st order to 68 2nd order to over 100 3rd order ones as its basic skeleton. Using the developed grid of sequence timelines, the diverse inter-disciplinary geological manifestations on the broad tectono-stratigraphically homogeneous supra-region of GTM (Gondwanian Tethyan Margin from Arabia to Australia) have been mutually integrated towards chronicling of events with precision never ever realized earlier. The giga-sequences GS-I to GS-IV comprising eight mega-sequences MS-I to MS-VIII deal with the Precambrian in brief. GS-V (¬ 635 ma onward) MS-IX (¬ 635-444 ma) and MS-XII (¬ 61.6 onward) include orogenies while MS-X (¬ 444-259 ma) and MS-XI (¬ 259-61.6 ma) are dominated by dismemberment tectonics. The prime focus is on the correlation of events across scores of sedimentary basins from outcrop to subsurface, onshore to offshore, marine to non-marine, shallow to deep water, plant to animal, micro to macro-fossils, and Proto-Paleo-Neotethys to Indian Ocean. Among the major Phanerozoic events time precised are the ¬ 500 ma Acantha Zone mega MFS accretion of the then alien TH to the Indian margin, and the ¬ 50 ma P8 Zone mega MFS impingement of India on Asia while the important dismemberment events include the ¬ 159 ma late Middle Oxfordian Orientalis Zone Schilli Subzone 1st order MFS initiation of the Indian Ocean which culminated in steps with oceanic separation of Sri Lanka from Antarctica at the ¬ 107 ma early Middle Albian Dentatus Zone mega MFS, ¬ 90 ma 1st order SB initiation of separation of Madagascar so also of Mascaranes basin, NER, Central Indian basin, Wharton basin, separation of Greater Seychelles from India at the ¬ 64.5 ma intra Danian 2nd order Quadratus Zone MFS and ¬ 24 ma Complanata Zone MFS thrusting due south of Greater Himalaya upon Lesser Himalaya. Indian Geological Sequences: Salient Features and Major Events is a valuable reference for researchers and scientists in the field of Earth Sciences. - Relates multi-dimensional geological events of one region to another in a vast supra-region through precisely dated sequence timelines - Links macro- and micro-evolutionary advent and extinction events to macro- and micro-geological events - Includes multidisciplinary data sources, from sedimentological, geochemical, and geophysical records

Book Synopsis An Australian Phanerozoic Timescale by : Gavin C. Young
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.
Book Synopsis The Great Ordovician Biodiversification Event by : Barry D. Webby
Download or read book The Great Ordovician Biodiversification Event written by Barry D. Webby and published by Columbia University Press. This book was released on 2004-04-14 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.

Book Synopsis Miospores and Organic-walled Microphytoplankton of Devonian-Carboniferous Boundary Beds (Bakken Formation), Southern Saskatchewan by : Geoffrey Playford
Download or read book Miospores and Organic-walled Microphytoplankton of Devonian-Carboniferous Boundary Beds (Bakken Formation), Southern Saskatchewan written by Geoffrey Playford and published by . This book was released on 1993 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Core samples obtained from five petroleum exploration wells in southern Saskatchewan provide the material basis for this first detailed palynological study of the subsurface Bakken Formation in the northern part of the intracratonic Williston Basin. The Bakken Formation is a holomarine unit that constitutes part of the organic-rich, predominantly black shale sedimentary sequence that accumulated around latest Devonian-earliest Carboniferous time in the Williston Basin and in the contiguous northern Rocky Mountains region of the Western Canada Basin. The Bakken is a distinctive stratigraphic marker because of its lithological consistency in toto and its three subunits, all of which were sampled for this investigation. The Bakken is economically important as a probable petroleum source (shale members) and because of its reservoir properties (arenaceous member).
