On a correlation between surface remanent magnetism and chemistry for the lunar frontside and limbsImage-processing techniques applied to orbital data have revealed an inverse correlation between lunar surface remanent magnetism and surface concentrations of Fe and Th on a scale of 250 km and greater. The effect can be understood in terms of the implantation of magnetism early in the history of the moon, coupled with the chronological sequence of highland-mare crustal differentiation. The exception seen at the Fra Mauro region suggests the presence of a source of magnetization sometime within 0.3-0.6 b.y. after formation of the moon.
