A comprehensive introduction to palaeomagnetism offering a comprehensive treatment of theory and practice. Written in a clear and concise style that will be understandable to undergraduate students and researchers alike, it analyzes the palaeomagnetic record over the whole of geological time, from the Archaean to the Cenozoic, and goes on to examine the impact of past geometries and movements of the continental crust at each geological stage. Topics covered include theory of rock and mineral magnetism, field and laboratory methods, growth and consolidation of the continental crust in Archaean and Proterozoic times, Palaeozoic palaeomagnetism and the formation of Pangaea, the geomagnetic fields, continental movements, and configurations and mantle convection since Archaean times, and more.
