Reversals of the Earth's magnetic field

Reversals of the Earth's Magnetic Field
Measurement of the direction and intensity of magnetism in rocks of different ages produces a record of past changes in the magnetic field of the Earth. Of particular interest are reversals of the magnetic field.
In this authoritative book, Professor Jacobs reviews the details of reversals and discusses the results of recent investigations, including their implications for an understanding of the source of the terrestrial magnetic field, and their role in helping to establish a geological timescale. He also presents a critical discussion of the recent theories which attempt to relate geomagnetic field reversals to past climate and to the extinction of faunal populations in previous geological epochs.
The synthesis of the latest observational results with current geomagnetic theory makes this text a timely contribution to an important field, which has previously been covered only by scattered review articles and particular studies in... Tovább

The synthesis of the latest observational results with current geomagnetic theory makes this text a timely contribution to an important field, which has previously been covered only by scattered review articles and particular studies in research journals.
Reversals of the Earth's Magnetic Field will be a welcome reference work for postgraduate and advanced undergraduate students in the earth sciences, and an invaluable addition to the libraries of all research workers concerned with palaeomagnetism.
Cover: the cover illustration shows the magnetic reversal chronology for the last 80 Myr laid out alongside the Hawaii-Emperor island chain. Further details are given in chapter 3 (courtesy: Elsevier Scientific Publishing Co).

JOHN ARTHUR JACOBS has been Professor of Geophysics at the University of Cambridge since 1974, and is a Fellow of Darwin College. Sometime Professor at the University of British Columbia and Killam Memorial Professor of Science at the University of Alberta, he holds the Gold Medal of the Canadian Association of Physicists and the Centennial Medal of Canada. His previous publications include Physics and Geology (with J T Wilson and R D Russell), The Earth's Core and Geomagnetism, Geomagnetic Micropulsations, A Textbook on Geonomy and The Earth's Core.
Professor Jacobs delivered the 1983 Sir Harold Jeffreys lecture to the Royal Astronomical Society on Reversals of the Earth's Magnetic Field. Vissza
