Crustal structure interpreted from magnetic anomalies

Reviews of Geophysics
By: , and 



In this review, we discuss publications during the last quadrennium (1987–1990) that used aeromagnetic data, marine magnetic data, satellite magnetic data, and rock magnetic and petrologic data to provide information on the sources of magnetic anomalies. Abstracts and papers by non‐U.S. authors are not described.

The publications reviewed reflect increased integration of rock magnetic property and petrologic studies with magnetic anomaly interpretation studies, particularly in deep crustal magnetization, exploration for hydrocarbons, and inversion of marine magnetic anomalies. Interpretations of aeromagnetic data featuring image display techniques and using the horizontal gradient method for locating magnetization boundaries became standard. The magnetic anomaly map of North America appeared, the first such map of an entire continent. MAGSAT data contributed to the development of a new model for the magnetization of the oceanic crust. Forward modeling of sources of magnetic anomalies contributed to a wide range of geologic investigations on land, and inverse magnetic modeling techniques became popular for marine geologic investigations.
