Abstract

Lunar Prospector gamma-ray spectrometer spectra along with counting rate maps of thorium, potassium, and iron delineate large compositional variations over the lunar surface. Thorium and potassium are highly concentrated 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 measurements from Clementine and the Lunar Prospector neutron detectors.

摘要

“月球勘探者号”伽马射线光谱仪的光谱，以及钍、钾和铁的计数率图，描绘出了月球表面巨大的成分变化。钍和钾高度集中在近月面西侧的月海及其周围，而在南极艾特肯盆地则较少。铁伽马射线的计数率图显示的表面铁分布，总体上与“克莱门汀号”及“月球勘探者号”中子探测器的其他测量结果一致。
