Many geological features of the Earth's lithosphere create variations in the Earth's magnetic field that can be detected by satellites. The resulting magnetic anomaly maps can provide new insights into the tectonic features and broad structures of the lithosphere. This book documents the acquisition, reduction and analysis of satellite magnetic field data in the study of the Earth's lithosphere. The text considers issues of interpreting data, summarizes various interpretation methods, considers rock magnetism concepts and sources of variation in magnetism, and provides a complete summary of published maps and the methods used to create them. Mapping and interpreting lithospheric fields from satellite magnetic data has resulted in the new subdiscipline of geomagnetism. Advanced students and researchers will find that The Magnetic Field of the Earth's Lithosphere provides a much needed review of this important topic.
