Crustal Magnetic Model

A model of the magnetization of the earth's crust, based on measurements of the magnetic field made by NASA satellites Magsat, OGO-2, OGO-4, and OGO-6. This model was also designed to be consistent with other information on the crustal magnetic field such as the higher magnetizations found in areas underlain by rocks of Archean age and the contrast in the magnetic properties and thickness of continental and oceanic rocks.
