Scientific paper

The Lunar Prospector (LP) mission returned the first global elemental maps of major elements O, Si, Al, Ti, Fe, Mg, and Ca. The maps were submitted to the Planetary Data System (PDS) archive in June of 2002. Maps are provided for all of the elements at 5 spatial resolution, corresponding to 1790 equal area pixels. This resolution is sufficient to investigate large-scale compositional variations within major lunar terranes. Further work is underway to develop 2 and 0.5 maps for a subset of these elements, which will reduce the effects of instrumental mixing and will enable more meaningful comparisons to the sample collection. We believe that we have discovered a highland province that may contain an abundance of Mg-rich troctolitic or noritic materials. We are investigating several possibilities for the origin of this province, one of which is the exceptional abundance of late-stage Mgsuite intrusions at a high level in the lunar crust. We will use the entire Lunar Prospector elemental data set to investigate candidate hypotheses.
