Reversals of the Earth's Magnetic Field
Reversals of the Earth's Magnetic Field
By measuring the direction and intensity of magnetism in rocks of different ages, a record of the Earth's magnetic field in the past can be obtained. This 1994 book deals with the particular case of reversals of the Earth's magnetic field. These have played a major role in the development of plate tectonics and in establishing a geological time scale. The magnetism of rocks is discussed in some detail with a warning of possible misinterpretations of the record. Observational results and theories are reviewed with special attention to the structure and geometry of the transition field. Changing conditions at the core-mantle boundary, their effect on reversals, the generation of plumes and the possible correlation of reversals with tectonic changes, ice ages or mass extinctions are thoroughly discussed, including suggested periodicities in the reversal record and in other geophysical data.
- Only text dealing specifically with reversals of the Earth's magnetic field

Reviews & endorsements
'The author writes lucidly and well, and the book offers a comprehensive overview of all things related to reversals … The book definitely belongs on the shelves of all researchers and graduate students working with aspects of reversals and should be purchased by all research libraries.'
