Book Synopsis Magnetic Methods and the Timing of Geological Processes by : Luigi Jovane
Download or read book Magnetic Methods and the Timing of Geological Processes written by Luigi Jovane and published by Geological Society of London. This book was released on 2013 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetostratigraphy is best known as a technique that employs correlation among different stratigraphic sections using the magnetic directions defining geomagnetic polarity reversals as marker horizons. The ages of the polarity reversals provide common tie points among the sections, allowing accurate time correlation. Recently, studies of magnetic methods and the timing of geological processes have acquired a broader meaning, now referring to many types of magnetic measurements within a stratigraphic sequence. Many of these measurements provide correlation and age control not only for the older and younger boundaries of a polarity interval, but also within intervals. Thus, magnetostratigraphy no longer represents a dating tool based only on geomagnetic polarity reversals, but comprises a set of techniques that includes measurements of geomagnetic field parameters, environmental magnetism, rock-magnetic properties, radiometric dating and astronomically forced palaeoclimatic change recorded in sedimentary rocks, and key corrections to magnetic directions related to geodynamics, palaeocurrents, tectonics and diagenetic processes --
Book Synopsis Rock Magnetic Cyclostratigraphy by : Kenneth P. Kodama
Download or read book Rock Magnetic Cyclostratigraphy written by Kenneth P. Kodama and published by John Wiley & Sons. This book was released on 2014-10-06 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock magnetic cyclostratigraphy merges environmental magnetism, in which rock magnetic measurements are used to detect past environmental change, and cyclostratigraphy, in which cyclic variations of lithology or a sedimentary rock’s physical properties are related to astronomically-forced paleoclimate change. In addition to providing paleoclimate data, cyclostratigraphy can establish high-resolution chronostratigraphy for a sequence of sedimentary rocks, even at distant times in Earth’s history. This book provides an overview of concepts underlying these two techniques, recipes for the time series analysis of cyclostratigraphy, and case studies to illustrate the variety and breadth of problems addressed by rock magnetic cyclostratigraphy. New Analytical Methods in Earth and Environmental Science Because of the plethora of analytical techniques now available, and the acceleration of technological advance, many earth scientists find it difficult to know where to turn for reliable information on the latest tools at their disposal, and may lack the expertise to assess the relative strengths or limitations of a particular technique. This new series will address these difficulties by providing accessible introductions to important new techniques, lab and field protocols, suggestions for data handling and interpretation, and useful case studies. The series represents an invaluable and trusted source of information for researchers, advanced students and applied earth scientists wishing to familiarise themselves with emerging techniques in their field. All titles in this series are available in a variety of full-colour, searchable e-book formats.

Book excerpt: This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.
Book Synopsis Exploring the Earth under the Sea by : Neville Exon
Download or read book Exploring the Earth under the Sea written by Neville Exon and published by ANU Press. This book was released on 2017-10-24 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the Earth under the Sea brings to life the world’s largest and longest-lived geological research program, which has been drilling over many decades at many locations deep below the ocean floor to recover continuous cores of sediment and rock. Study of these materials has helped us understand how the Earth works now, how it has worked in the past and how it may work in the future. The cores are a wonderful source of information on the dynamic processes that form and reform the Earth, both beneath the ocean and on land. The results have revealed climate and oceanographic change on different time frames, the history of life in the sea and on land including global mass extinctions, the extraordinary story of the great masses of ‘extremophile’ microbes that live beneath the sea bed, the nature of the giant earthquakes and tsunami generated at the trenches where tectonic plates collide, and the nature of submarine volcanoes and metalliferous deposits. This book outlines the technology and enduring international partnerships that underlie the scientific ocean drilling accomplished by the first phase of IODP, currently involving 23 countries. It highlights the important role of Australian and New Zealand scientists in the program, and the great scientific benefits we have derived from our partnership since joining IODP in 2008. As well as the scientific summaries, there are personal accounts by shipboard scientists of how they found life at sea on two-month expeditions, working 12-hour shifts on a noisy drill ship.

Book Synopsis Palaeomagnetism by : Donald H. Tarling
Download or read book Palaeomagnetism written by Donald H. Tarling and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeomagnetism and archaeomagnetism are fascinating specialized studies because they are applicable to such a wide range of problems in geology, archaeology and geophysics. They can also be undertaken cheaply, when compared with most other geophysical techniques, and, at first sight, simply. In fact, real comprehension of the magnetic processes that have occurred in rocks and other types of material over several thousands or many millions of years is still extremely difficult to assess and measure. On this basis, this book cannot explain all such features, nor can it attempt to cover all the actual and potential applications of the method. All that can be attempted is to give an impression of the ways in which such techniques can be used in a wide variety of fields, and how these techniques are usually applied. The magnetization of rocks is, in fact, one of the earliest of the true sciences, but we are still not in a position to answer many of the problems posed. Consequently some of the examples given of applications are, essentially, state-of-the-art comments, rather than being a review as such. The changing position of the geomagnetic poles with time is still not adequately defined, for example, and some of the more recent conventional views are given, although the emphasis is placed on more subjective, probably more controversial, evaluations.

Book Synopsis History of Terrestrial Mammals in South America by : Thomas Defler
Download or read book History of Terrestrial Mammals in South America written by Thomas Defler and published by Springer. This book was released on 2018-12-19 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a non-technical approach in covering the evolution of South American mammalian fauna throughout geological history, and discusses how South America has changed due to mammalian invasions. Unlike other works on the subject, this book attempts to answer several crucial questions that often go unmentioned together in one cohesive monograph. What was the fauna like before the American interchange? What were the origins of the now-extinct groups when northern species arrived and out-competed them? How did the modern mammalian fauna come into being with such disparate animal groups? This information is given from a historical perspective throughout the book's 15 chapters, and is presented in an easily graspable fashion by mostly avoiding technical language. The book is written for academics, scientists and scholars engaged in paleontology, zoology and evolutionary biology, but may also appeal to a larger audience of general readers interested in mammalian evolution. The book begins with an introduction, describing the tools necessary to interpret the evolutionary history of South American mammals in geological terms and some of the early people who helped found South American mammalian paleontology. Chapter 2 describes the Mesozoic first mammals of Gondwana and what we are learning about them, dominant before the K/T extinction event. Then chapters 3 through 8 cover the Cenozoic, or "Age of Mammals", highlighting the major mammalian groups of South America that replaced the earlier mammals of Gondwana. These groups include the marsupials, native ungulates, the xenarthrans (armadillos, anteaters, sloths), the caviomorphs (rodents), and the platyrrhine monkeys. Chapters 9 and 10 address the Antarctic La Meseta fossils and the Colombian La Venta fossil faunal assemblages. Chapter 11 discusses the neotropical mammals that invaded the Caribbean Islands, and illustrates the influence South America has had on adjacent faunas. Chapter 12 describes the origin of the Amazon River and the role it has played in the evolution of the mammals and other flora and fauna. Chapter 13 tells the story of the Great American Biotic Interchange (GABI), and chapter 14 follows this up with a discussion of the Pleistocene mammal communities and their eventual extinction. Chapter 15 concludes the text by discussing the modern mammals of South America, and how despite the extensive Pleistocene extinctions there is still a lot of mammalian diversity in South America.

Book Synopsis Induction Soundings of the Earth's Mantle by : Vladimir Semenov
Download or read book Induction Soundings of the Earth's Mantle written by Vladimir Semenov and published by Springer. This book was released on 2017-07-27 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the heart of this book is the generalized theoretical approach that is applied to investigate the geoelectrical structure of the Earth’s mantle. It also analyzes the results of regional and global induction sounding of the Earth’s mantle and compares them with the results obtained by other geophysical methods. The generalized theoretical approach employs the Induction Law as a basis for identifying extended relations between magnetic field components, including their plane divergence, impedances and spatial derivatives. The estimations of impedance values and spatial derivatives are performed using the theory of stochastic processes. The book also considers the external sources of magnetic fields used for sounding the Earths mantle from the modern theory perspective, as well as the problem of coincidence of magneto-variation and magnetotelluric methods. Further, it discusses secular variations in the Earth’s resistance caused by non-induction sources, factors that are correlated with the number of earthquakes in the region and shifted in time with global indexes. It is a valuable resource for scientists applying deep induction soundings or interested in the structures of and processes in the Earth’s interior.
