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 insights into the tectonic features and broad structures of the lithosphere. This book, which was originally published in 1998, 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, summarises various interpretation methods, considers rock magnetism concepts and sources of variation in magnetism, and provides a summary of published maps and the various methods used to create them. Mapping and interpreting lithospheric fields from satellite magnetic data has resulted in the sub-discipline of geomagnetism. Advanced students and researchers will find this book to be of interest.
