Abstract
Lunar Prospector gamma-ray spectrometer spectra along with counting ra te maps of thorium, potassium, and iron delineate Large compositional variations over the lunar surface. Thorium and potassium are highly co ncentrated in and around the nearside western maria and Less so in the South Pole-Aitken basin. Counting rate maps of iron gamma-rays show a surface iron distribution that is in general agreement with other mea surements from Clementine and the Lunar Prospector neutron detectors.
