Possible Fossil Lunar Magnetism Inferred from Satellite Data

Abstract

Magnetization of selected nonmare areas, principally on the moon's far side, is inferred from positive disturbances in the magnitude of the magnetic field exterior to the magnetic signature of the lunar cavity observed in magnetometer data from the lunar orbiter Explorer 35. A less favored model for the field perturbations involves variations in the thickness of the low-conductivity crustal layer of the moon.
