The continental drift controversy. 2, Paleomagnetism and confirmation of drift /
Resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revol...

- Cover ; THE CONTINENTAL DRIFT CONTROVERSY: Volume II: Paleomagnetism and Confirmation of Drift; Dedication; Title; Copyright; Contents; Foreword; Acknowledgments; Abbreviations; Introduction; Note; 1: Geomagnetism and paleomagnetism: 1946-1952; 1.1 Breaking the impasse: the three main paleomagnetic groups; 1.2 Blackett and Runcorn begin their years together at the University of Manchester (1946-1949); 1.3 Blackett's fundamental or distributed theory of the origin of the geomagnetic field and Runcorn's introduction to it.
- 1.4 Elsasser develops a self-exciting dynamo in Earth's core as the source of the geomagnetic field1.5 Runcorn and colleagues carry out the mine experiment and discriminate between fundamental and core theories; 1.6 Blackett and Runcorn become interested in paleomagnetism; Runcorn accepts a position at the University of Cambridge; 1.7 Work at the Carnegie Institution in Washington and the case for a geomagnetic field without gross changes; 1.8 Graham develops field tests of stability; 1.9 Graham and others at the Carnegie Institution abandon the fold test.
- 1.10 Graham opts for self-reversals rather than field reversals1.11 Igneous baked contact test of stability; 1.12 Hospers arrives in Cambridge, 1949: his early education and commencement of Iceland surveys; 1.13 Hospers' first results from Iceland, 1950-1951, and genesis of Fisher's statistics; 1.14 Consistency or dispersion as a test of paleomagnetic stability; 1.15 Runcorn arrives in Cambridge, 1950, decides to work on paleomagnetism, and hires Ted (E.) Irving, 1951; 1.16 Irving's early education and undergraduate years.
- 1.17 Irving and Runcorn's first work, July through December 1951: only red beds give coherent results1.18 Irving devises a paleomagnetism test of continental drift, autumn 1951; 1.19 Realization in 1943 by Sahni that paleomagnetism could be used to test continental drift; 1.20 Irving initiates his test of motion of India; 1.21 Why Runcorn and Irving did not immediately redirect all their work to test continental drift; 1.22 Reaction of Blackett and Runcorn to Irving's work; 1.23 Summary; Notes.
- 2: British paleomagnetists begin shifting their research toward testing mobilism: summer 1951 to fall 19532.1 Outline; 2.2 Blackett initiates and Clegg leads the paleomagnetic group at Manchester; 2.3 Clegg builds a new magnetometer at Manchester; 2.4 The Manchester group expands and focuses on the Triassic redbeds; 2.5 Irving investigates the origin of magnetization of the Torridonian and begins magnetostratigraphic survey; 2.6 Irving completes magnetostratigraphic survey of the Torridonian; 2.7 Fisher defends mobilism.
